Synopsis

Securing EAS Through Message Authentication

While the security measures that we require radio and television stations, cable television systems, satellite radio and video services, and other entities required to participate in the EAS (collectively, “EAS Participants”) to implement in the accompanying Report and Order are necessary to prevent bad actors from exploiting poor security hygiene by EAS Participants, they are not sufficient to prevent our nation's adversaries from originating false alerts. To better secure EAS against cyberattacks, we propose to require EAS Participants to reject Common Alerting Protocol (CAP) EAS messages that do not include a valid digital signature. Digital signatures work by encrypting a hash or “fingerprint” of data with a “private [encryption] key” known only by the signer. The corresponding “public key”—typically made publicly or semi-publicly available—can decrypt a message encrypted using the “private key.” Thus, the “public key” ensures that a message encrypted using the corresponding “private key” is authentic (since only the entity that possesses the “private key” could have produced that encrypted message). Effective key management ensures that this process functions properly by controlling the issuance, distribution, and revocation of both public and private keys so that both originator and receiver have the correct valid keys. Public keys are issued as “digital certificates,” typically by certificate authorities that issue and manage certificates for public, private, and government entities. For CAP alerts sent through the Integrated Public Alert and Warning System (IPAWS), IPAWS maintains the public keys for all alert originators including itself. Because IPAWS digitally signs all alerts it issues, EAS devices acquire IPAWS's digital certificate (with the IPAWS public key) to authenticate alerts issued by IPAWS. While digital signatures are currently required by IPAWS, EAS Participants are only required to reject EAS messages that include an invalid digital signature. Our rules still allow EAS Participants to transmit EAS messages with no digital signature at all.

Digital Alert Systems, Inc. (DAS) believes that “the FCC's rules should be amended to require authentication and digital signatures for every CAP message received by an EAS CAP device, not just those received from FEMA IPAWS,” and advocates for “harden[ing] authentication/authorization throughout the system, to prevent spoofing and maintain confidence in alerts.” Washington State Emergency Management Division asserts that “[s]ystems should incorporate end-to-end authentication to prevent spoofing, tampering, or false alerts[,] [includ[ing] digital signatures, secure handoffs between IPAWS and carriers, and safeguards to ensure the alert received by the public matches exactly what the originator sent.” These comments reinforce the Communications Security, Reliability, and Interoperability Council (CSRIC) VI's finding that “[t]he importance of high confidence in sender authenticity is especially apparent in a public safety context,” and its recommendation that EAS Participants should not be permitted to transmit CAP messages that lack a digital signature. We agree with these commenters and believe that our proposal represents a major step forward in securing CAP EAS alerts. We seek comment on this view. Do alerts that lack digital signatures pose a high risk to EAS, and what kinds of harm could they cause? Are there any other public safety benefits that would arise from all EAS CAP alerts being authenticated? We believe that compliance with this requirement would be technically straightforward for EAS Participants because their EAS equipment already must authenticate signed CAP EAS messages. We seek comment on this view.

We seek comment on how this requirement would affect alerting authorities that originate CAP EAS messages. When the Commission required EAS Participants to reject alerts with invalid digital signatures in 2018, it declined to mandate digital signatures for all transmitted CAP EAS alerts because many state and local alerting authorities were not yet using IPAWS or CAP-based digital signatures. Currently, however, we understand that there are more than 2,000 federal, state, local, tribal and territorial alerting authorities that use IPAWS, which requires digital signatures for alerts distributed through its system. Does this mean that most state and local alerting authorities would be unaffected by this requirement since they are already signing alerts for distribution through IPAWS? We seek comment on the extent to which state and local CAP systems other than IPAWS support digital signatures and whether this proposal would undermine the ability of those systems to send alerts. To the extent that these systems do not support alert authentication, we seek comment on the steps that would be required to enable that functionality and how long those steps would take to complete.

While there are numerous benefits to alert authentication, there may also be risks. According to CSRIC VI, these risks include delaying alert message delivery and increasing the chance that a valid alert will be rejected as invalid. Have those risks materialized since the Commission required the rejection of CAP EAS alerts with invalid digital signatures in 2018? Have there been any notable cases in which valid alerts have been erroneously delayed or rejected? If we were to require the rejection of CAP EAS alerts that lack digital signatures, would that level of risk stay the same or materially increase? For example,

during the 2023 nationwide EAS test, only 23 EAS Participants reported problems related to the CAP EAS alert's digital signature, which is a very low percentage of the 20,682 EAS Participants that took part in the test. Is there any reason to expect that there would be significantly more failures during future tests if we were to adopt our proposal? Are the risks to non-IPAWS EAS CAP messages any different than for IPAWS messages? Should we take any steps to mitigate risks, including the possibility of key management and authentication failures?

We also seek comment on the feasibility, effectiveness, and costs of requiring EAS Participants to authenticate (
i.e.,
digitally sign) legacy EAS alerts, which are sent via the EAS Protocol. As explained by CSRIC VI, a digital signature requires two things: (1) a “hash” of the message to be signed, and (2) access to the public key used to decrypt that encrypted hash. Hashing refers to a process of scrambling data according to any one of many algorithms designed for that purpose. Hashed data cannot be altered, which ensures the authenticity of the hashed data. When CSRIC VI examined this issue in 2018, it determined that legacy EAS may be vulnerable to attack, but also determined that it faces technical challenges in implementing digital signatures. Unlike CAP alerts, legacy EAS is severely limited in how much data it can convey because the data that comprises the alert is converted into audio for transmission over broadcast. Adding the data necessary for a digital signature would delay alert message transmission and, in turn, delay the public's receipt of emergency alerts. According to CSRIC VI, adding a digital signature with a key length of 2048 bits would add 8.6 seconds, if sent twice with the header code strings, to the time required to validate and process the alert's header code strings. This delay could be significant because unlike CAP alerts received from IPAWS, legacy alerts may be relayed from one EAS Participant to another, and all entities sending the alert would need to create a hash of the alert using their digital signature before repackaging it for rebroadcast. In the legacy EAS “daisy chain” in which EAS Participants monitor one another as sources of alerts, the time it takes to authenticate an alert would likely be multiplied for each EAS Participant in the chain. We seek comment on the extent to which the public's receipt of EAS messages could be delayed as a result of an authentication requirement for legacy EAS. According to CSRIC VI, “[t]o fully implement a digital certificate/hash validation schema, every potential issuer of an EAS message would need to obtain (and be accredited) for an alert origination digital certificate[, which] could include many EAS Participants themselves.” CSRIC VI adds that “[p]resuming the FEMA IPAWS digital certificate was used for this purpose, both FEMA and the broadcast industry would be presented with a requirement to obtain, and maintain, these additional digital credentials.”

CSRIC VI also raised issues with reliance on the internet for checking the required public and private encryption key certificates, encryption key management related to managing signing keys for all participants, and interoperability with existing consumer equipment. For the digital certificate/hash validation schema to function properly, the EAS device would require the digital certificate for every EAS Participant and alert originator from which it might receive an alert. Digital certificates typically are valid for one year and therefore are constantly being renewed. Acquiring such certificates requires internet access and would require regular checking for renewed certificates. Accordingly, loss of internet access could prevent acquisition of current digital certificates necessary for alert validation involving an alert originator or EAS Participant relaying an alert whose certificate has been updated since the last version stored in the EAS device. We seek comment on how to address these challenges, including the non-conformity of legacy equipment that is no longer supported by software updates. Would the National Weather Service (NWS), which originates the vast majority of EAS alerts, be able to digitally sign the alerts it issues over the air via National Oceanic and Atmospheric Administration (NOAA) Weather Radio (NWR)? Would inclusion of a digitally signed hash in a legacy alert impact the operability of the embedded base of consumer and enterprise emergency radios that trigger off of the EAS protocol header codes? Would the audio portion of an EAS message remain susceptible to attacker manipulation and replay attacks even if the alert header itself were to be authenticated? Is the threat that our nation's adversaries may exploit the weaknesses of legacy alerts likely and severe enough to outweigh the difficulty, limitations, and effect on availability associated with solutions?

If we were to require EAS Participants to only transmit digitally signed legacy EAS alerts, we seek comment on how to best implement that requirement. Where should the digital signature be placed in relation to the header codes? Could it replace part of the attention signal? What elements of the header code string should be covered by the signature? Could we add the four-digit year to the elements covered by the signature without adding them to the header codes as transmitted? Assuming the data rate of the current AFSK (Audio Frequency-Shift Keying) encoding of the header codes is too slow to include the signature without unacceptable delay of the audio alert, how should the signature be encoded and how many seconds would it take? What specific protocols and standards would need to be developed or modified to add digital signatures to legacy EAS and how long would it take to develop them? How would these changes impact existing systems like consumer, first responder, and enterprise emergency and weather radios, and Alert FM receivers? Are there solutions that would minimize these impacts? Should the Commission take any actions to promote effective management of the key infrastructure needed to digitally sign legacy EAS messages? Sage states that, if the Commission were to require authentication for legacy EAS, every EAS Participant and alerting authority would require its own digital signature to maintain the same capabilities as the current system. Is that accurate, or are there more efficient approaches through which key distribution and updates can be managed? One approach to streamline and simplify key management could be to limit the ability to sign legacy EAS alerts to only certain entities within each state. Could this approach work, and if so, to which entities should it be limited? What is the likelihood that access to signing certificates could be compromised during widespread disaster conditions, widespread IP disruption (
e.g.,
route hijacking, ransomware, or router table poisoning), or during routine use? Is that risk distinct from similar risks to signing certifications for CAP EAS alerts, and if so, how? What, if any, role should the Commission have in mitigating these risks? In the event that we allow EAS Participants to use EAS software, would that create a unique opportunity to introduce legacy EAS authentication at a time when costs could be lowest? To what degree should we consider the potential impact of future quantum computers on any authentication requirement we impose, and should we account for that risk through post-quantum cryptography? If

so, how should that be reflected in our rules?

We seek comment on whether there are any alternative ways to address the vulnerability of legacy EAS alerts while preserving the resiliency of EAS and its assurance of availability under widespread outages of normal communications paths. Are there any other common sense, technically feasible steps that we should take to secure EAS?

Bolstering the Reliability of Emergency Alerts

In the 2025 Notice of Proposed Rulemaking (
Alerting Modernization NPRM
) that commenced a ground-up review of the nation's alerting systems, the Commission sought comment on the goals of emergency alerting, which commenters agree should include providing authorities with a reliable way to rapidly notify the public of emergencies that may put them at risk. Commenters emphasized that reliability is fundamental to achieving the core goals of the nation's alerting systems. As Xperi Inc. observes, “[d]uring emergencies, the public needs timely, accurate, and actionable information” to help protect lives and property. Similarly, Washington State Emergency Management Division explains that, in their view, “[a]lerts must be accurate, consistent, and non-duplicative to avoid fatigue and maintain public trust.” The issues we seek comment on, and the rules we propose today aim to improve the reliability of the nation's alerting systems to ensure that they meet our core goals and provide enhanced protections to the public.

Preventing Duplicate Alerts Through a Universal Identifier.
When we sought comment on alert originators' expectations for delivery of alerts, several commenters explained that both alert originators and the public expect that alerts will be presented to the subscriber once and that the subscriber will not receive duplicates. As the Washington State Emergency Management Division writes, “[a]lerts must be . . . non-duplicative to avoid fatigue and maintain public trust.” We agree, and tentatively find that the goals of the nation's alerting systems are undermined when the public receives duplicate alerts and that EAS and WEA should be designed to better detect and suppress duplicate alerts.

To reduce confusion and alert fatigue, we propose to require Participating Commercial Mobile Service (CMS) Providers to identify whether an alert is a duplicate through the use of a common message identifier, or “universal alert message ID,” that will be assigned to each WEA message they receive and transmit. Even though § 10.500(g) of the Commission's rules already requires WEA-capable mobile devices to detect and suppress duplicate WEA messages, the Commission still frequently receives complaints that members of the public receive duplicate alerts. In investigating this issue, we have learned that Participating CMS Providers use carrier-specific identification numbers to determine whether an alert already has been received by a mobile device. This means that a mobile device that receives and displays an alert on one provider's network and then later receives the same alert while roaming on a different provider's network will display a duplicate alert. We have also learned that one Participating CMS Provider uses different WEA identification numbers on each generation of wireless network technology it has deployed. When this provider transmits a WEA message, its subscribers are at risk of receiving duplicate alerts when they move between generations of wireless network technology within their own home network. We identified this as a potential source of some of the duplicate alerts during the 2025 Los Angeles County wildfires, which caused confusion and complaints during the height of a life-threatening emergency. We believe that using a universal alert message ID would eliminate many duplicate alerts that are currently received by subscribers. If a WEA message contained the same unique identifier, irrespective of the Participating CMS Provider network from which it was transmitted, mobile devices would be better equipped to identify and suppress duplicates. Would the use of a unique identifier prevent duplicate WEA alerts caused by changes from one generation of equipment to another, or if the mobile device received the alert from a cell repeater? We believe that the introduction of a universal alert message ID will lead to an increase in the public's trust in WEA messages and help prevent consumers from opting out of WEA. We seek comment on this analysis. Are there other situations in which a universal alert message ID could help prevent duplicate alerts? For example, do hybrid satellite-terrestrial networks pose new alert duplication risks that arise from the transmission of alerts from different sources?

We seek comment on what the source of a universal alert message ID should be. We believe that universal alert message IDs can be derived from unique identification numbers that IPAWS already assigns to each CAP message it receives. We understand, however, that this unique ID is very long and would add significant data overhead to WEA message transmittals if it were to be included in WEA metadata. We seek comment on whether IPAWS' unique identification number can be shortened in a manner that does not add significant data overhead to WEA message transmittals and yet enables mobile devices to determine if an alert is a duplicate. Are there other uniquely identifying CAP fields that should be used instead or in addition to IPAWS' unique identification number? We believe that it would be feasible to use an appropriate hashing function to generate a fixed-size identifier suitable for use from one or more CAP fields. We seek comment on hashing functions that could do so with minimal collisions (duplicate values for two different inputs) and on the acceptable size of the hash value. In the alternative, we seek comment on other methods that could be used to generate a universal alert message ID that remains truly unique over the twenty-four hour retention period of WEA messages.

We seek comment on whether IPAWS should be responsible for creating this universal alert message ID and passing it on to Participating CMS Providers. Are there any technical or practical challenges that weigh against the identifier being created by IPAWS? Alternatively, would it be feasible and more efficient for Participating CMS Providers to receive the existing identifier from IPAWS and use the same technique to shorten it as part of their processing of alerts? Should the universal alert message ID originate in alerting authorities' alert origination software, and if so, how can the identifier be designed to ensure that alerts originating from different sources are not duplicating the identifier? Should the design of the universal alert message ID be determined by the Federal Emergency Management Agency (FEMA) or through a collaborative standards development process? We seek comment on any alternatives to a universal message ID that Participating CMS Providers could implement to prevent the presentation of duplicate alerts and how those alternatives could be implemented.

We also seek comment on whether the use of a FEMA-IPAWS generated identification number would help enable other lifesaving developments in the alerting ecosystem. For example, would a universal alert message ID help the NWS implement “Threats-in-Motion” alerting that could allow NWS to continually update the target area and

message content without generating duplicate alerts or causing alert fatigue? The Alliance for Telecommunications Industry Solutions (ATIS) notes that there are some scenarios that are challenging for WEA, notably “complex, multi-stage emergencies that require dynamic updates at brief intervals due to ongoing changes in the threat itself of the location impacted. . . . [where] updates presented to consumers in a short period of time that are similar in nature may be perceived as duplicates.” We seek comment on whether a universal alert message ID could aid in solving this issue. Are there other ways in which a universal alert message ID can expand WEA's potential?

We seek comment on whether the universal alert message ID could also be implemented in EAS, and if so, whether it would be useful. For example, could a universal alert message ID help prevent duplicate EAS messages? Today, EAS equipment performs a byte-by-byte comparison between EAS messages to detect duplicates. If any relevant information in the EAS message header is different than the previously received and stored messages, it will not be deemed a duplicate. This can cause duplicate alerts in several scenarios, including when the location codes in legacy EAS alerts and EAS CAP messages do not match. Would using a universal alert message ID to identify duplicate alerts, rather than a byte-by-byte comparison of the relevant information in EAS message headers, help alert originators like NWS prevent the transmission of duplicate alerts? What, if any, other changes would be necessary for EAS to realize the benefits of a universal alert message ID? Would legacy EAS need to be updated to rely solely upon the universal alert message ID for duplicate suppression? What, if any, other benefits would a universal alert message ID have for EAS? We seek comment on whether a universal alert message ID could help realize DAS's “One message, many paths,” vision, wherein alert originators can compose a single alert that is distributed to WEA, EAS, and NOAA Weather Radio. What would be the most efficient way to implement a universal alert message ID in EAS? What specific characteristics would the universal alert message ID need to have to minimize implementation costs?

Ensuring the Consistent Transmission of WEA Messages.
To ensure that alerting authorities can rapidly notify the public of emergencies, emergency alerting must be resilient and must not unnecessarily delay the public's receipt of alerts. To better support this goal, we seek comment on whether to require Participating CMS Providers to rebroadcast WEA messages at least once every sixty seconds throughout an alert's active period. The Commission has long been concerned that Participating CMS Providers' inconsistent WEA transmission practices threaten the timely delivery of WEA messages and WEA's resiliency. Among major Participating CMS Providers, one broadcasts each WEA messages every minute throughout the duration of the alert's active period, some only broadcast each WEA message a single time, while still others broadcast each WEA message a limited number of times after a delay of several minutes. We believe that requiring consistent transmission of WEA messages, as recommended by several commenters, will make WEA more resilient to ephemeral service disruptions that may result in mobile devices not receiving the initial transmission of an alert, as well as ensure that people entering an alert's target area after the initial transmission have a chance to receive it. We seek comment on this belief and the tentative conclusions that support it. Will the routine rebroadcast of WEA messages improve the rate at which people within an alert's target area receive messages that are intended for them? Will it improve the rate at which people entering the target area after the alert's initial transmission receive WEA messages? Will it improve WEA's resilience to ephemeral service disruptions that may coincide with an alert's transmittal?

Is at least once every sixty seconds the right periodicity for the rebroadcast of WEA messages, balancing the need for timely, reliable alert delivery against the potential network load? The fact that at least one Participating CMS Provider already rebroadcasts each WEA message every sixty seconds supports our belief that compliance with this requirement would be both technically feasible and reasonable. Previous comments in PS Docket Nos. 15-91 and 15-94 support a sixty second interval. ATIS favored rebroadcasting alerts at regular, one-minute intervals, as did Verizon, although Verizon expressed a preference to apply this policy only for “the first 15 minutes of an alert's active period” to “provide alert originators and consumers alike a more consistent experience across different service providers while enabling wireless networks to efficiently manage multiple inbound alerts from” IPAWS. How do Participating CMS Providers that rebroadcast WEA messages every sixty seconds manage bandwidth resources on the control channel on which they transmit WEA messages, particularly when they receive multiple inbound alerts in quick succession? Are there any circumstances in which Participating CMS Providers should be allowed to retransmit WEAs at a periodicity other than at least once per minute throughout an alert's active period?

To further mitigate the risk of duplicate alerts, we seek comment on whether Participating CMS Providers should cease retransmission of WEA messages with a 24-hour active period five minutes before the end of that period. We are aware of incidents in which the transmission of WEA messages near the end of a 24-hour active period has resulted in mobile devices displaying duplicate alerts. In these circumstances, differences between how the CMS network and mobile devices determine the age of an alert can cause devices to purge their memory of 24-hour-old alerts too early and therefore “forget” that they have already displayed an incoming alert to the user. Is stopping retransmission of a WEA message before the end of its active period the best or only way to mitigate this risk of duplicate messages? Is it appropriate for us to permit Participating CMS Providers to implement a buffer period at the end of their retransmission of WEA messages with a 24-hour active period, and if so, is five minutes the right length for that buffer? We seek comment on any public safety or technical concerns that this approach may implicate.

Improving the Accuracy of Alert Geotargeting

As part of our reexamination of EAS and WEA, we sought comment on which transmission capabilities were needed for an alert and warning system to meet its objectives. Commenters widely recognize that accurate geotargeting is “critical” to accomplishing alerting systems' goals, and they overwhelmingly support improving those capabilities. King County comments that “[w]e strongly agree that geographic targeting is a necessity for a modern alerting system.” Sonoma County Department of Emergency Management comments: “Geographic targeting is also critical. Alerts should be as precise as possible to reach only those at risk.” Art Botterell writes that “[m]embers of the public rarely object to a warning that is relevant to them, at their location and in their circumstances. . . . The best mitigation is to improve the targetability of warning alerts to minimize alert

delivery to people for whom the alerts are not relevant.”

Commenters also suggest that problems with geographic accuracy unfortunately may be undermining alerting objectives, with the Harris County, Texas Office of Homeland Security & Emergency Management (Harris County) observing that the public is being “inundated with messages that are not relevant to them.” While the California Governor's Office of Emergency Services states that “[t]his [problem] is particularly evident in cities, where there can be overshoot of messages in densely populated areas,” Alaska resident Shawn Williams observes that geotargeting overshoot can be equally pernicious in rural areas. When people are inundated with alerts and warnings that they do not perceive as relevant to them, it can “dilute urgency,” “trust can erode,” and “alert fatigue” can occur. Consequently, people may ignore EAS and WEA messages that are intended for them or disable WEA warnings altogether. APCO International states that “alert originators are less likely to use alerting systems” because of the negative consequences of poor geotargeting. The New York City Emergency Management Department's comment stands for the corollary premise that “the more precise . . . [emergency alerting] can be, the more it will be used by alert originators.” Similarly, the Sonoma DEM states that the geotargeting of “[a]lerts should be as precise as possible to reach only those at risk, while allowing modest overshoot to capture travelers entering hazardous areas.” In light of these concerns, in the sections below, we propose and seek comment on measures to improve the accuracy of geotargeting for both WEA and EAS.

Strengthening WEA Geotargeting by Eliminating Outdated Exceptions.
Commenters offer several suggestions on ways to improve WEA geotargeting. We propose to implement these suggestions by eliminating the existing exceptions to the Commission's WEA geotargeting requirements that allow more than 0.1 of a mile of overshoot in some circumstances. While Participating CMS Providers are required to deliver WEA messages to “100 percent of the target area with no more than 0.1 of a mile overshoot,” our rules allow for exceptions for “network infrastructure [that] is technically incapable of matching the specified target area.” The Commission has provided a non-exhaustive list of circumstances in which a Participating CMS Provider's network may be considered to be “technically incapable” of matching the target area, including legacy networks and legacy mobile devices and mobile devices with location services disabled. The other listed “exception” is for “when the target area is outside of the Participating CMS Provider's network coverage area.” Unlike the exceptions for legacy infrastructure and devices, and locations services being disabled, which allow for overshoot that goes beyond 0.1 of a mile, the exception for “when the target area is outside of the Participating CMS Provider's network coverage area” addresses a separate aspect of the geo-targeting requirement, that WEA messages be delivered to “100% of the target area.” Although included as an exception, it would not be reasonable to expect a Participating CMS Provider to deliver WEAs outside its service area. In our proposed rules, we maintain the idea that Participating CMS Providers are not expected to deliver WEAs outside of their coverage areas by limiting the delivery and display requirement to “100 percent of opted-in WEA-capable mobile devices that are connected to its network and located in the Alert Message's target area.” Even though technically incapable networks are nonetheless required to deliver WEA messages to their best approximation of the target area, the Commission and its federal partners frequently receive complaints that WEA messages are being received outside of the target area. As discussed above, this causes alert fatigue and diminishes the usefulness of EAS and WEA. We believe that eliminating these exceptions will reduce overshoot and make WEA more accurate, which, in turn, will make WEA a more predictable tool that will provide greater confidence to alert originators that alerts will be seen by, and only by, the intended audience. We seek comment on these views.

Exemptions for Legacy Networks and Devices.
We propose to eliminate the geotargeting exception for legacy networks and devices. When the Commission adopted the current geotargeting requirements in 2018, it expected that these exceptions would be time-limited as legacy networks shut down and older devices were churned out of the market. We understand that many Participating CMS Providers either have already retired or are actively retiring their 2G and 3G networks. Which, if any, currently deployed networks cannot support geotargeting as currently described in our rules? To what extent do Participating CMS Providers and their subscribers continue to rely on these networks for the delivery of WEA messages? If any Participating CMS Providers continue to rely upon networks that still cannot be upgraded to support today's WEA geotargeting requirements, we seek comment on those providers' timelines for sunsetting those networks. To what extent have mobile devices that do not support today's geotargeting requirements already churned out of the market?

Exemption for Disabled Location Services.
We propose to eliminate the geotargeting accuracy exception for devices with location services disabled. As currently implemented, disabling location services on a WEA-capable mobile device will prevent the device from conducting a geofence and will therefore cause it to present every WEA it receives to the subscriber, even if the device is located far outside of the target area. Participating CMS Providers use device-based geofencing to comply with the geographic targeting requirements of § 10.450(a), which limits overshoot to 0.1 miles on technically capable infrastructure and devices. Device-based geofencing compares the mobile device's location with the coordinates included in the WEA message. If the device is within the target area, the device will present the alert. If not, the device will suppress presentation of the alert. If, however, location services are disabled, the device cannot determine its location and cannot perform a geofence. If a geofencing-capable device receives an alert, and it cannot perform a geofence, it will present the alert. When the Public Safety and Homeland Security Bureau (Bureau) partnered with 37 emergency management agencies across the country to conduct localized WEA tests in 2022, it found that more than two thirds of geofencing-capable devices failed to correctly suppress the alert. The Bureau also found that at least some of these failures likely occurred because devices had location services disabled. Wireless providers confirmed to Bureau staff that the main cause of overshoot in devices that were capable of performing a geofence was the devices' location services being disabled. Are disabled location services a primary cause of targeting failures on devices that are otherwise technically capable of geofencing, as this evidence suggests? If not, what else could account for these failures? Alternatively, is it possible that device-based geofencing, as widely implemented by original equipment manufacturers and Participating CMS Providers, is not capable of consistently meeting the Commission's accuracy requirement?

To reduce the number of geotargeting failures, the King County Office of Emergency Management recommends

“that location services should be forced on when a device receives a WEA—the same as for 911 calls—to determine whether an alert is applicable to the device holder.” We believe that this approach would greatly improve the accuracy of WEA overall and would better align with the expectations of consumers, who likely expect WEA to be accurate regardless of their device's location settings. We seek comment on this view. Would requiring mobile devices to force location services on when a WEA is received reduce WEA overshoot? When users purchase a geofencing capable device and disable location services, do they expect to receive accurate, geographically relevant alerts? Similarly, do purchasers of WEA-capable mobile devices who disable location services have an expectation of privacy that precludes the use of that information for purposes of public safety? Are subscribers aware that turning off location services may result in them receiving WEAs that were not intended for them? Could receiving such geographically irrelevant alerts cause subscribers to opt out of receiving WEA messages? How would mobile devices need to be technically modified to support the ability to turn on location services when a WEA is received?

Previously, several commenters raised privacy concerns related to eliminating this exception. ATIS states that “[u]nlike 9-1-1, WEA is not a user-initiated request for assistance at the time of the event. . . . consumer trust and privacy, are considerations on always requiring location services to be enabled that may result in consumers' choosing to opt-out of WEA.” The Electronic Frontier Foundation echoes this concern, stating that “[a]n individual's ability to opt-out of geolocation services and thus be able to move about daily life without being systematically tracked is also a matter of safety.” According to King County Office of Emergency Management (King County), however, “[i]f those location services data are not shared off the device, there would be no privacy concerns.” We believe King County is correct that mobile device location data is never shared outside of the device for the purpose of WEA geofencing. Can these concerns be addressed by placing limitations on how location information that is collected for WEA can be used? For example, we propose that when the receipt of a WEA message turns on a device's locations services, the acquired location information would be prohibited from being used for any purpose other than WEA. We also propose to prohibit Participating CMS Providers from transmitting this location information over their networks. We propose that any location information collected to perform a geofence be deleted immediately after the geofence was performed. If WEA were to be able to turn on and access location services even for those people who have disabled location services on their devices, should we require location services to be disabled immediately after the location information was made available for WEA? When users disable the location services on their mobile device, should they receive a disclosure that doing so will reduce the geotargeting accuracy of WEA messages? Would these measures be sufficient to balance the public safety value of ensuring that location information is always available to WEA while protecting consumers' privacy? Are these measures technically feasible? Are there any additional or alternative measures we should consider to protect the privacy of subscribers and balance those privacy concerns against the benefits of getting accurate WEA messages? For example, should consumers be provided with the option to turn on location services solely for WEA? Should consumers receive a disclosure upon switching location services off on their devices letting them know that it may result in them receiving WEA messages that are not relevant to them?

We seek comment on any other technical feasibility concerns attendant to receipt of a WEA prompting mobile devices to obtain a fresh location fix. CTIA states that “such an approach may not be technically feasible given differences in the way [9-1-1 and WEA] operate.” What specific technical differences between how WEA and 911 operate pose a challenge? Could these challenges be overcome through appropriate standards and mobile device software updates? Apple airs an additional concern about the implication of location services always being on for mobile device battery life, stating that “GPS usage—particularly in areas with weak signals—can be very power intensive” so “if an emergency involves power outages, a consumer might reasonably choose to conserve device battery life over the ability to receive more targeted alerts.” We seek comment on whether our proposal to require location services to be disabled immediately after the location information was made available for WEA would address this concern. We seek comment on any refinements to our proposal that might be appropriate to preserve mobile device or network resources while improving WEA geotargeting's performance.

Exemption for Geocodes.
We propose to require WEA messages that geotarget alerts by using Federal Information Processing System, Codes for States and Counties (FIPS) codes, which are also referred to as “geocodes,” to achieve the same level of accuracy as alerts sent using a polygon or circle. Today, if an alerting authority targets an alert using a FIPS code instead of a polygon or circle, the Commission's rules do not require the alert to comply with the 0.1 mile limit on geographic overshoot. As a result, according to CTIA, “the alert will not contain the geographic coordinates necessary to activate [device-based geofencing]. . . .” The result will be that any mobile device that receives such a WEA message will present the alert to the subscriber, even if the device is far outside the target area. Requiring WEA messages that use FIPS codes to be as accurately targeted as alerts that use circles or polygons would greatly reduce instances of geographic overshoot, making WEA a more useful tool for alert originators and better ensuring that subscribers only receive alerts that are relevant to them. We seek comment on these views.

We believe that it is technically feasible for WEA messages that use FIPS codes to be as accurate as messages that use circles or polygons. When the Commission adopted the enhanced geotargeting requirement, it was persuaded that mobile devices could not yet perform a geofence using a county code because there was no authoritative mapping of U.S. counties to polygon coordinates and because of technical concerns related to the transmission of polygon coordinates that track geocodes and the conversion of geocodes to polygons at the mobile device. Since then, the U.S. Census Bureau has published a mapping of county codes to polygon coordinates. This freely available database may enable IPAWS or participating wireless providers to translate a geocode into a polygon before it reaches a mobile device so that the mobile device can use it for the purpose of geofencing using available polygon smoothing techniques. Would increasing the limit on the number of vertices that can be used to describe a polygon, as requested by the NWS and Colorado 911 Authorities and Public Safety Agencies, facilitate converting geocodes into coordinates, as well as make it easier for alert originators to use polygons? What challenges or drawbacks to increasing the number of vertices exist and how could they be addressed? Alternatively, polygons relevant to the user's location could be

automatically retrieved, stored locally on mobile devices, and used when a WEA message is received that includes a FIPS code that matches a stored polygon. Would these approaches be successful at improving the accuracy of WEA messages that use FIPS codes? Could available polygon smoothing, simplification, encoding, or compression techniques address any concerns about fitting polygons derived from geocodes in WEA transmissions? How much mobile device storage would be required to maintain a mapping of county geocodes to corresponding polygons? Could industry take steps to minimize this burden, such as by retrieving polygons for geocodes specified in a WEA message upon receipt of the message or as a background task when a mobile device moves into a new region? Are there any additional methods that could be implemented to improve the accuracy of WEA messages that use FIPS codes? What are the benefits and trade-offs of these approaches. Should we require Participating CMS Providers to implement a specific method for improving the accuracy of WEA messages that use FIPS codes, or should we remain agnostic to how accuracy is improved so long as these messages are no longer received more than 0.1 miles outside of the target area?

We seek comment on any other causes of geographic overshoot that arise from the design or technical implementation of WEA. What steps can we take to eliminate or mitigate these other causes of geographic overshoot? Are there any additional or alternative steps that we can take to reduce or eliminate instances of geographic overshoot?

Incentivizing EAS Geofencing.
We propose to improve the accuracy of EAS geotargeting by permitting, but not requiring, EAS Participants to take advantage of detailed location information that is often available in CAP EAS messages. Because EAS Participants are currently restricted to targeting alerts by using county codes, it can be difficult for them to identify alerts that are targeted to very small geographic areas. Even if they could identify these situations, EAS Participants transmit EAS alerts to facilities' entire service areas, which are often large. As DAS comments, “[b]y design, once an EAS alert is issued, everyone watching that channel receives it.” As REC Networks states, “since EAS was originally intended for national messages, more localized messages are just an afterthought.” Alerting authorities and EAS equipment manufacturers take the view that EAS is being underutilized because of these limited geotargeting capabilities. For example, during the January 2025 Los Angeles County wildfires alerting authorities did not use EAS to transmit evacuation orders to avoid delivering the alert to people for whom it was not intended, which could have caused unnecessary panic and potentially moved people into—rather than out of—harm's way. King County Office of Emergency Management “would like to see similar [WEA-like geotargeting] capabilities developed for EAS. Currently sending an EAS in our area would alert six counties, theoretically reaching over 8,000 square miles and 4.5 million people. This is far too broad for any practical purpose.” DAS states that improvements to EAS geotargeting “could reduce alert fatigue and make alerts more relevant.” Because many CAP EAS messages include WEA-supported circles or polygons in addition to county codes (legacy EAS messages do not contain geo-targeting information more accurate than the county codes), we believe that the most immediate approach to improving EAS geotargeting would be to allow EAS Participants to use those circles and polygons as an alternative to county codes.

We believe this approach will allow EAS Participants to more precisely identify the geographic area to which a given CAP EAS alert is relevant and be better informed as to whether it makes sense to transmit the alert to their audiences. This helps EAS Participants strike a balance between transmitting EAS messages to affected communities while minimizing the deleterious effects of alert fatigue. We seek comment on this view. Do EAS Participants have an interest in using circles and polygons when making decisions about which state or local alerts to transmit? How would EAS Participants integrate circular and polygonal targets into their decision-making about whether to transmit an alert? Will permitting targeting via polygons encourage innovation and lead to the deployment of new capabilities that can potentially make alerts more accurate? If so, what kinds of capabilities might be developed? Can circles and polygons assist EAS Participants in delivering alerts to only a portion of their audience instead of all of it, and if so, are there types of EAS Participants that are better positioned to accomplish this than others? Do EAS equipment manufacturers believe that there is sufficient interest in these capabilities to financially justify bringing those capabilities to market? Do the proposed changes to our rules provide sufficient flexibility to EAS Participants that may want to consider using the coordinates in a CAP message to determine whether to broadcast an EAS alert? If not, what alterations are necessary to facilitate and encourage EAS Participants to take advantage of the coordinate information in CAP-based EAS alerts? As an alternative approach, should the Commission require, instead of merely allow, EAS Participants to use circles and polygons when targeting alerts?

Several commenters tout the broadcast television standard ATSC 3.0 as a means of improving emergency alert geotargeting. When the Commission authorized ATSC 3.0 as the next generation broadcast television standard in 2017, it observed that the standard would offer enhanced geotargeting of emergency alerts and required ATSC 3.0 broadcasters to comply with the EAS rules. The Advanced Warning and Response Network (AWARN) Alliance, ATSC: The Broadcast Standards Association, Sinclair, Inc., the National Association of Broadcasters (NAB), and the Oregon Department of Emergency Management advocate for increased use of ATSC 3.0 as a way to transmit geotargeted emergency alerts. Would our proposal improve the ability of EAS Participants relying on ATSC 3.0 to more accurately target alerts to audience members in specific geographic areas? If so, how would these EAS Participants conduct this targeting?

Improving Target Area Descriptions in EAS Alerts—Partial County Alerting.
We propose to delegate authority to the Public Safety and Homeland Security Bureau to consider and adopt new EAS location codes that will make EAS messages more understandable to local communities. NWS has expressed concerns that existing location names can be potentially confusing or misleading to the public. For example, in Monroe County, Florida the “southwest” subcounty code might be used for alerts relevant to Key West. People in Key West, however, would be confused by an EAS message that described the target area as “Southwest Monroe County” because they may not associate that description with Key West. To provide greater flexibility to alerting authorities, additional location names could be encoded and transmitted in legacy EAS messages using currently unused combinations of EAS location codes. For example, the American National Standards Institute (ANSI) standard for FIPS codes and the Commission's EAS rules establish that the code for Monroe County, Florida is “12087.” The code “12088,” on the other hand, is currently unused and

could potentially be assigned to “Key West” for EAS purposes.

We expect that this approach will increase the authoritativeness and effectiveness of EAS messages by providing alerting authorities with a more flexible list of locations for targeting alerts. More commonly used location names would be less likely to confuse alert recipients about whether an alert is intended for them and would likely provide greater certainty about whether a received alert is intended for the recipient. We seek comment on our proposal and these views. In what other scenarios might it be beneficial for alerting authorities to be able to use more flexible location codes? Are these scenarios common enough to justify creating a streamlined process for adopting new location codes? What risks arise from creating location codes for EAS in this fashion? Should we consider an alternative technical implementation, such as expanding the county subdivision character of six-digit geocodes to allow the use of letters, which could then be assigned to specific locations? Are there more effective ways to reduce consumer confusion about the locations to which EAS messages are targeted that we should consider?

We believe that delegating authority to the Bureau to seek comment on and adopt new EAS location codes will promote efficiency. Under this process, alerting authorities or State Emergency Communications Committees would request that the Bureau create a new EAS code for a particular location. We propose that request would be required to include a map with a circle or polygon to identify the geographic area to which the new code would apply, provide reasons why the new code should be created, and explain why the existing location codes are inadequate for members of the public that would receive alerts in that location. The Bureau would request comment on these requests by way of a Public Notice and act upon each request based on the merits presented. We seek comment on this approach.

Enhancing Alert Effectiveness

In the
Alerting Modernization NPRM,
we sought comment on the kinds of information the nation's alerting system should convey to the public to ensure people take appropriate protective actions, and asked whether there are changes that should be made to how alerts are presented to make them easier for people to understand. We believe that emergency alerts will be most effective when they provide people with information that they can quickly and easily understand. Harris County is “strongly in favor of allowing for the inclusion of visual media in WEA messages [as recommended by CSRIC IV because they] enhance understanding and help bridge accessibility gaps.” Several other commenters generally support enhanced emergency messaging that includes visual media and recognize its public safety value, which provides additional information, expands accessibility, and improves understanding of how to stay safe, but note that speed and security must come first. The Snohomish County Department of Emergency Management cautions that creating and transmitting multimedia content could delay alert delivery.

We agree with commenters that using modern technology to enhance alert message content beyond traditional text and audio will benefit public safety but also agree that these enhancements should not come at the expense of other important aspects of emergency alerting. Accordingly, we take a modest first step toward enhanced media emergency alerting by seeking comment on whether to require EAS and WEA messages to include a simple, easily recognizable symbol representing the underlying emergency event. We also seek comment on the U.S. Geological Survey's (USGS) recommendation that the receipt of a WEA earthquake alert should trigger an announcement of the alert message text using text-to-speech. USGS is the Federal agency responsible for monitoring and notification of earthquakes, volcanic activity, and landslides in the United States and is tasked with providing public warnings of imminent strong earthquake shaking. USGS provides earthquake emergency notices through its earthquake early warning (EEW) system called ShakeAlert® in the states of Washington, Oregon, and California with plans to expand to system to Alaska. In addition to being sent through their proprietary system, ShakeAlert earthquake alerts are also sent via WEA.

Promoting the Use of Symbols for Alerts.
We seek comment on whether to require EAS and WEA messages to display standardized symbology that identifies the threat type. We expect that the use of symbols could potentially improve comprehension for people with disabilities and people with limited English reading proficiency, hasten public reactions to alerts, and reduce milling. For example, Notify NYC & Cornell Tech have previously found that the use of incident-specific symbols doubled participant comprehension and literacy. We seek comment on these views. The Language & Accessibility for Alerts & Warnings Workgroup, the Oregon Department of Emergency Management, North Carolina Emergency Management et al., and NWS support the inclusion of standardized symbology in EAS and WEA messages. DAS acknowledges that while EAS and WEA function effectively, additional features could enhance the systems and “the Commission should rather look at steps towards including more modest multimedia resources with alerting . . . [which] could consist of further introducing standardized symbology/iconography to accompany EAS and WEA alerts, as well as basic images and graphics that may be carried on an optional basis by appropriate services.” DAS further states that “EAS modernization should include supplemental lightweight visuals, such as static graphics, such as the [Visually Integrated Display Symbology (VIDS)] iconography, which add clarity. Static VIDS graphics and symbology offer the greatest increase in relevance for the least additional expense” and that its “experience demonstrates that these enhancements are technically feasible; DASDEC devices already aggregate media and support symbology.” FEMA has previously argued that the use of graphical symbols could improve alert message interpretation by individuals with limited English proficiency.

DAS and the State Broadcasters Associations recommend a voluntary approach to applying symbols to emergency alerts. DAS believes multimedia enhancements, including standardized symbology, should remain optional in order to preserve the timeliness and reliability of emergency alerts. We seek comment on whether the inclusion of symbols in EAS or WEA messages would necessarily delay or potentially prevent the public's receipt of those messages and, if so, to what extent. Are there implementation approaches to supporting symbols in EAS and WEA messages, such as having them preloaded on end-user devices rather than transmitted along with message text as NWS and Verizon have suggested, that are technically feasible and that could mitigate latency and reliability concerns? The State Broadcasters Associations state that “comments [filed in this proceeding] demonstrate that the broadcast industry is continuing to evolve its emergency communications capabilities . . . perhaps in ways alert originators do not yet know or anticipate. These innovations have the potential to add pictorial or video content to broadcast EAS alerts and emergency messages . . .” They recommend the broadcast

industry be allowed to evolve public alerting capabilities through continued industry innovation, rather than rulemaking. We seek comment on any innovations EAS Participants or Participating CMS Providers have implemented that may contribute to the potential to include emergency alert symbols in EAS and WEA messages. On what timeframe do EAS Participants and Participating CMS Providers believe that the display of symbols or multimedia content alongside alert messages will become widespread?

If we were to require EAS and WEA to integrate a standardized symbol set, we seek comment on which symbol set we should rely upon. For example, should EAS and WEA symbols be based on the National Alliance for Public Safety GIS (NAPSG) Foundation symbol library, which is publicly available at no cost and is supported by FEMA? What other symbol sets should we consider? What are the benefits and drawbacks of each? The Rehabilitation Engineering Research Center for Wireless Inclusive Technologies previously found that, among sixteen “people who were Deaf and primarily used ASL for communication,” the presence of NAPSG symbology did not improve the participants' understanding of either the event or the recommended protective action. Is this representative of what we should expect for the effect on the public generally? We invite commenters to submit into the record any other studies conducted about the use of symbols or iconography in emergency alerts.

We also ask commenters to address presentation guidelines for symbols in EAS and WEA, respectively. Is there value in creating a common look and feel among EAS and WEA messages such that the same or similar presentation guidelines should apply to both systems? Or are EAS and WEA so technologically distinct that a similar look and feel for symbols presented via these systems would be impracticable to achieve? We seek comment on how emergency alert symbols should be presented along with EAS and WEA messages. Where should emergency alert symbols be located relative to the display and the alert message text? What size should the symbols be relative to the display? Should symbols have some transparency, particularly for EAS, where the programming content behind them could otherwise be unnecessarily obscured? For how long should an emergency alert symbol persist on an emergency alert display? How should symbols be displayed when there are different types of emergencies pending for the same geographic area simultaneously? Should symbols appear with alert message text and disappear at the end of the visual crawl or when the user dismisses the message? Or should a symbol persist on the display for the entirety of an alert's active period in a discrete but visible location, such as in the corner of the television screen or on a mobile device's lock screen or home screen? We seek comment on whether the persistent presentation of an emergency alert symbol could bring the existence of an emergency condition to the awareness of people that could otherwise miss it, such as television viewers that tune in during an EAS message's active period but after the EAS visual crawl has already completed and the broadcast has returned to regularly scheduled programming.

We seek comment on technical considerations relevant to the presentation of emergency alert symbols. Could this functionality be enabled on WEA-capable mobile devices through a software update? What EAS Participant systems would be involved in the process of displaying an EAS-related symbol on a television screen, and how would those systems display it? What steps would need to be taken for these systems to support this capability? Would any changes to standards be needed to enable symbols to persist on-screen for the duration of the alert's active period?

Amplifying WEA Earthquake Alerts.
The faster the public understands an alert, the faster they can react. This is particularly important during events that occur without prior notice or predication. Accordingly, we seek comment on USGS's recommendation that the receipt of a WEA earthquake alert should trigger a verbal announcement using text-to-speech. While WEA's attention signal and vibration cadence are intended to quickly grab subscribers' attention, no information about the nature of the underlying emergency event is communicated during that time unless a subscriber accesses their device to read the text of the message. Having additional seconds to react can make a significant difference in public safety outcomes during the most time-sensitive, no-notice emergencies, such as earthquakes. USGS believes a text-to-speech verbal announcement of imminent earthquake shaking would provide the fast, actionable information consumers need to take protective action during an earthquake. In support for this view, USGS identifies precedent for spoken emergency alerts from the National Fire Alarm and Signaling Code, which requires in-building private mass notification system emergency alerts (
e.g.,
fire alerts) to include an intelligible audio message along with a visible notification recommendation. USGS argues that social science supports the finding that people respond to speech-based auditory icons and text-to-speech faster than they respond to attention sounds that are not based on speech, which USGS says is key for effective earthquake warnings. We seek comment on USGS's recommendation. If spoken emergency alerts hasten protective actions relative to a generic attention signal in response to in-building fire alerts, does it stand to reason that spoken emergency alerts would similarly hasten protective actions in response to WEA messages? Should we consider requiring additional types of WEA messages to be automatically spoken by default, such as the most common and most imminent WEA messages, for which we have created standard templates?

Can text-to-speech produce speech that is accurate, audible, and comprehensible to most listeners? Earthquake alerts may be a good candidate for text-to-speech functionality because they always contain the same, authoritative text: “Earthquake! Expect shaking. Drop, Cover, Hold On. Protect yourself now.—USGS ShakeAlert.” We seek comment on this belief. USGS states that, in addition to hastening protective actions for all alert recipients, text-to-speech provides critical information to people with access and functional needs (
e.g.,
visual impairments). How should WEA text-to-speech interact with mobile devices connected to screen readers or other accessibility tools? Are there other discrete consumer groups that would benefit from the availability of text-to-speech for WEA messages, such as people with limited literacy skills? We also invite commenters to address whether Participating CMS Providers could support this functionality in English, Spanish, and other languages. If so, should we require WEA earthquake alerts to include text-to-speech announcements in Spanish and other languages? Would text-to-speech make WEA messages more effective or less effective for subscribers in crowded environments wherein several devices may receive an alert at the same time? Would text-to-speech for earthquake alerts lead consumers to opt out of WEA?

We seek comment on the technical implementation issues around text-to-speech for WEA. To what extent do WEA-capable mobile devices already support text-to-speech? Can consumers already enable text-to-speech for WEA

on certain makes and models of devices, and if so, how? What, if any, technical changes would be required to enable mobile devices, whether or not they are already capable of text-to-speech, to automatically use text-to-speech to read WEA messages, including earthquake alerts? If we were to require Participating CMS Providers to support text-to-speech for earthquake alerts, should the presentation of that speech begin immediately after a mobile device's presentation of the WEA audio attention signal, or should it replace the audio attention signal? Should users receive that speech by default or should we require that they would need to affirmatively opt in to receive WEAs via text-to-speech, either through their mobile device settings or through an option presented along with the text of the message itself?

In addition, we seek comment on USGS's recommendation that we require a unique audio attention signal to accompany earthquake alerts, rather than the standard common audio attention signal associated with all WEA messages. We seek comment on how consumers would react to a unique audio attention signal for earthquake alerts. Is the danger posed by earthquakes unique enough to warrant a specialized attention signal? Would consumers respond to an alert with a unique attention signal more quickly, or would it cause consumer confusion? Social science suggests that people's understanding of emergency alerts is generally low, and significant public education would be required to teach people to recognize a distinct attention signal for earthquake early warnings. We seek comment on these findings. We also seek comment on whether the addition of a new attention signal may increase consumer frustration with the alerting system as a whole by generating an additional form of an audio signal that they already find to be intrusive. If we were to require the use of a unique audio attention signal, what should that signal be?

Removing Unnecessary Alerting Requirements

In the
Alerting Modernization NPRM,
we sought comment on ways the Commission should modernize the nation's alerting systems to improve their usefulness and better leverage modern technology while minimizing burdens on stakeholders. Many commenters argue that removing unnecessary alerting requirements is an essential step in ensuring that alerting remains efficient, reliable, and aligned with the core objectives of alerting. With respect to WEA, for instance, The Competitive Carriers Association (CCA) encourages the Commission to “take actions to reduce the cumulative regulatory burdens of the program on smaller and rural providers” in particular, because “simplify[ing] the WEA program . . . [will] promote maximum participation in the program.” CCA asks that this proceeding build upon the Commission's Delete, Delete, Delete proceeding. Similarly, with respect to EAS, NTCA—The Rural Broadband Association (NCTA) argues that “it is time to comprehensively reexamine alerting, including the regulatory obligations for cable operators and other EAS Participants, to better reflect modern technology and consumer preferences.” ACA Connects likewise urges the Commission to “reduce, rather than expand, the burdens of participation in EAS for smaller cable operators,” to reduce the risk that unfunded mandates will drive small cable operators out of the cable video business. In light of these concerns, we advance the following proposals to reduce burdens on EAS and WEA participants while ensuring that these systems continue to advance with modern technologies and consumer expectations. We also respond to the March 31, 2025, Petition for Rulemaking filed by the National Association of Broadcasters (NAB) requesting that the Commission clarify or modify its rules to allow EAS Participants to support EAS through software-based technology instead of dedicated physical equipment.

Approving the Use of EAS Software.
We grant NAB's Petition for Rulemaking to initiate a rulemaking proceeding on its proposal to permit use of software for EAS alert processing as an alternative to the requirement to use dedicated hardware. The petition has made the showing required for such petitions, and we find that it discloses sufficient reasons in support of the action requested to justify the institution of a rulemaking proceeding. At the outset, we observe that among the core purposes that Congress established for the Commission are “promoting safety of life and property through the use of wire and radio communications,” promoting “rapid [and] efficient” wireline and wireless services, and “encourag[ing] the provision of new technologies and services to the public.” Today, EAS still depends heavily on stand-alone hardware located outside the core processing systems that broadcast, cable, and satellite services now use daily. We believe that as the industry shifts toward IP-centric architectures, it is important that the Commission consider whether there is an opportunity to modernize EAS processing to better support public safety and to improve operational efficiency for EAS Participants.

We agree with the majority of commenters that granting NAB's petition will provide an opportunity to align the EAS rules with modern technologies and potentially reduce unnecessary burdens on EAS Participants. For example, Sage states that the EAS rules requirements are based on outdated assumptions “no longer correct for many, and possibly most, devices in modern usage.” Furthermore, Sage notes that “[s]oftware-only EAS would not preclude the use of a traditional standalone hardware device, but would allow for closer integration of EAS into radio and TV broadcast chains where EAS is made to work within the system, rather than trying to force the existing system to accommodate EAS.” NCTA indicates that “NAB's proposal to permit EAS Participants to elect software-based EAS solutions may present the Commission with another opportunity to ensure that emergency alerting keeps pace with modern technology,” and “may be of use to cable EAS Participants as well.”

We also agree with commenters like CMG Media Corporation (CMG) that argue that the Commission should explore the technical and operational benefits that may arise from the use of EAS software, “includ[ing] streamlined operations, improved remote maintenance and control, and increased security of EAS equipment.” Commenters emphasize that the existing hardware-based EAS poses significant repair delays and reliability challenges, while a software-based approach could streamline maintenance and improve overall system performance. The Society of Broadcast Engineers (SBE) notes that when dedicated EAS equipment malfunctions “stations often have to locate, schedule, and deploy a contract engineer to physically diagnose and repair the malfunction. Additionally, the equipment must sometimes be physically shipped all the way back to the manufacturer for repair (or to be manually updated).” NCTA states “that the shipping time, distance between locations and the availability (or unavailability) of parts for older equipment can all contribute to delays in repairing EAS equipment,” and NCTA further states “there are occasionally defects that are more difficult to address or instances in which equipment takes longer to replace due to inventory limitations, for which

the Commission's current rule provides necessary time.” The Joint Commenters contend that software-based EAS could “improve the [EAS] system's effectiveness: for instance, by enabling systems to be repaired and updated much more efficiently through a software update or remote fix rather than factory repair of a physical device; by eliminating single points of failure through multiple instances of EAS software in diverse locations; and by facilitating the routing and targeting.” We believe that these are all appropriate reasons to explore whether the EAS rules can be improved by allowing EAS Participants to rely on EAS software.

Opposing commenters fail to convince us that the issue is not ripe for consideration or that rulemaking sought by NAB would conflict with the public interest, particularly given Congress's historic policy of considering the use of new technologies. DAS argues that the NAB Petition “offers no discussion of how such software-based systems would be verified, authorized, or audited for compliance with existing Commission rules,” adding that there is no “FCC process for certifying software-only EAS solutions.” DAS further comments that the NAB Petition does not address cybersecurity, and that “[t]here is currently no robust FCC cybersecurity standard tailored to EAS software platforms.” We observe that the need to develop equipment certification or approval requirements appears to be anticipated in the NAB Petition, and by its supporters. As Sage puts it, “[c]ybersecurity is an issue that needs to be taken into account; however, the issues are known, and are not fundamentally different than any other IT component of a broadcast facility.” In any event, we agree that certification and security are important aspects to be resolved with respect to the NAB Petition's proposal, but we also agree with NAB that these issues “are properly considered within a rulemaking proceeding,” and we address these issues below.

We also reject DAS's argument that NAB's proposal “may confer greater relative benefits on radio broadcasters—particularly those with simpler technical operations—than on television or cable operators, which already rely heavily on integrated, IP-capable workflows,” which DAS concludes “undermines the foundational principle that any revision to Part 11 must serve the public interest equitably across all EAS Participants.” Even assuming that DAS's assumptions about the benefits of NAB's proposals are accurate, the possibility that some EAS Participants might be able to implement a software-based EAS approach more easily than others would not be adequate grounds for declining to consider the issue.

DAS also argues that “[a] central tenet of the Commission's rulemaking authority under the Communications Act of 1934, as amended, is the requirement that any new regulation—or deregulation—must advance the public interest, convenience, and necessity,” adding that, “[i]n the context of emergency communications, the standard is even more stringent: Proposals must demonstrably enhance the reliability, reach, or effectiveness of life-saving public safety information.” DAS contends in this regard that “the Petition is silent as to how its request to allow software-based EAS solutions would achieve any tangible improvement in how alerts are received or understood by the public.” We observe that, as stated above, the NAB Petition has made the showing required for Petitions for Rulemaking, and discloses sufficient reasons to justify the institution of a rulemaking proceeding. Moreover, as the NAB Petition described it, software-performed EAS might enable “an immediate fail-over of functionality” to backup EAS software operating on systems in other locations. The NAB Petition adds, “[t]his feature is critical as many broadcasters have been forced to evacuate facilities due to environmental disasters and relocate to auxiliary facilities, abandoning their hardware-based EAS equipment when the public needs emergency messaging the most.” These functions strike us as potentially enhancing the reliability, availability and, potentially in times of outages, the reach of the EAS.

Implementing EAS Software.
Consistent with NAB's petition, we propose to permit, but not require, EAS Participants to use software-based EAS encoder/decoder technology instead of a dedicated EAS hardware device to process EAS alerts. As outlined above, the record developed in response to the NAB Petition demonstrates broad support for the concept of using software to perform EAS functions in place of dedicated EAS equipment. We tentatively agree with the Society of Broadcast Engineers that “permitting broadcasters to implement flexible software-based EAS equipment if they so choose allows EAS equipment to evolve, helps provide a potential lifeline to stations whose dedicated EAS hardware is no longer being manufactured, and spurs meaningful beneficial developments in the EAS ecosystem both at the station level and overall.” We anticipate that allowing use of software-based EAS would enable expeditious repairs, security updates, and compliance upgrades to an EAS Participant's provision of EAS alerting, as well as more easily enabling backup EAS coverage when the primary software-based EAS source becomes unavailable, as commenters have asserted. These beneficial aspects of EAS software should increase EAS availability, and potentially EAS security, which furthers our goal of providing alert originators with the ability to rapidly notify the public of emergencies. Enabling automatic fail-over to a backup EAS source would further our goal of providing communications during and after emergencies, when power and/or internet outages can impede or prevent regular EAS operations and other forms of communication to the public. NAB argues that “[t]his feature is critical as many broadcasters have been forced to evacuate facilities due to environmental disasters and relocate to auxiliary facilities, abandoning their hardware-based EAS equipment when the public needs emergency messaging the most.” We seek comment on these expectations.

More broadly, we anticipate that EAS software would be adaptable and could help support or drive the adoption of advanced alerting capabilities. To that end, we seek comment on whether there are aspects of EAS software or its integration within an EAS Participant's service delivery system that would better allow EAS Participants to voluntarily analyze, process, and present audio/visual messages, photos, maps, or other information provided or linked in a CAP EAS alert? Would software EAS be adept at performing geotargeting calculations, text-to-speech, speech-to-text, or other alerting functions? Would EAS software be capable of generating or passing through CAP alerts over secondary channels or subcarriers for consumption by end user devices capable of processing them? Are there any specific functions that EAS software could provide that are not available to EAS hardware devices and would be particularly beneficial to alert originators?

Flexibility is an important part of our proposal. We propose to allow EAS Participants to install EAS software in a single device (
e.g.,
a server or computer) that manages EAS functions within the EAS Participant's signal processing system. Alternatively, we propose to allow EAS software to be installed across multiple components within that system, thus enabling integration of different EAS functions across multiple system components. SBE, for example, contends that “[t]he Commission's rules should provide broadcasters with the

flexibility necessary for them to implement the best EAS solution for their station's specific operational circumstances.” In addition to the benefits described above, we believe that enabling flexibility in EAS software deployment may make compliance with EAS obligations easier to manage, and reduce costs for those EAS Participants that elect to use EAS software. We also anticipate that our approach may spur innovation in EAS alert capabilities by RF transmission system (and possibly cable system) equipment providers who integrate encoder/decoder software into their self-contained transmitter/signal processing systems. We seek comment on this proposal and our related analysis. Are there additional benefits that EAS software could provide that would further the goals we set out for the EAS and WEA alerting systems in the
Alerting Modernization NPRM
?

While providing flexibility is important, this goal needs to be balanced against the necessity of ensuring the reliability of the EAS. In the
Alerting Modernization NPRM,
we asked, among other things, whether alerting systems should also incorporate resilience to common causes of disruption to communications. In general, alert originators responding to these questions observed that ensuring delivery of alerts is critically important. As the Washington State Emergency Management Division put it, “[p]ublic warning must be reliable even during worst-case conditions.” Many of these commenters stressed the need for redundancy in the delivery of alerts. The New York State Division of Homeland Security and Emergency Services, for example, stated “[a]lerting systems should have a high degree of resilience, incorporating redundant systems and pathways to ensure that alerts are actually received by the public.”

To that end, we propose to require that EAS software—however it is integrated into or across the EAS Participant's signal processing system—be located at the EAS Participant's local facility used to provide service. For a broadcaster this would mean that EAS software would be required to be installed at the studio or transmitter site associated with its licensed service area. (By “studio,” we mean the local physical facility wherein programming is generated and/or compiled and processed for transmission.) For a cable communications service provider, this would mean that EAS software would have to be installed at the headend facility. We observe that this proposal would prohibit EAS from being generated within cloud-based systems or cloud-based third-party EAS services. Our proposal is grounded in concerns about the resilience of IP-based connections in the alerting context. With IP-based systems, functions previously performed on local equipment can be carried out anywhere in the world relying on internet or wide area networks to connect them. EAS software potentially has the same capability, relying on IP networks to bring in monitored audio sources and to output EAS alerts for insertion into programming at other locations. However, this reliance on IP networks could cause EAS Participants to be cut off from their EAS capabilities during emergencies that involve power outages or infrastructure damage, which are types of emergencies for which EAS has historically demonstrated to be useful. As MITRE states in a 2025 white paper, critical infrastructure sectors' emergency communications planning “should assume all standard commercial IP traffic and communications are unavailable in a wide area,” which would be inconsistent with installing EAS software at distant facilities. We further observe that our approach is consistent with the NAB Petition, wherein NAB states that it “is not seeking an off-premises, fully cloud-based approach.” DAS and NCTA also express concern that remote hosting and EAS software processing may diminish the Commission's capacity for oversight and enforcement.

We seek comment on limitations. Would our approach sufficiently mitigate risks associated with IP network failures? Are there other locations at which we should permit the use of EAS software that allow EAS to retain its signature resilience? Should we allow EAS software to be installed anywhere so long as the EAS Participant also locates and operates EAS software at the transmitter as a fail-over location? If we allow these kinds of network designs that require EAS software to be located at the transmitter as the fail-over location, should we also require that monitored sources be received at the same location so they also avoid being blocked by inoperable IP connections? Would some or all of these measures sufficiently ensure that EAS Participants using EAS software would be able to receive and transmit legacy and/or CAP alerts during most emergency situations when alert originators and the public need them the most? Are there additional or alternative requirements for the use of EAS software that we should adopt to ensure resiliency and fulfillment of the alerting goals discussed above? How should any of these requirements be effectively reflected in the language of our rules?

We also observe that some commenters raise market-based justifications for allowing use of EAS software. The NAB Petition, for example, argues that “the recent decision of Sage Alerting Systems, one of the two remaining EAS device vendors, to cease production of its [encoder/decoder] device due in large part to supply-chain problems acquiring legacy parts for original EAS hardware-only designs” illuminates the need to consider its EAS software proposal. The NAB Petition further contends that “[u]nder NAB's proposed approach, such manufacturing issues will not be a significant concern because the software will be able to operate on multiple existing hardware appliances or software processes already in use within broadcasting.” CMG argues that “[a]s time goes on the [supply chain] problem will worsen, and the Commission must consider what happens if the last vendor can no longer manufacture the required device or if a repair backlog results in communities missing crucial EAS messages.” CMG adds “[t]he Commission should not force broadcasters to rely on one vendor to provide EAS service or upgrade their devices when there are viable alternatives that can relieve pressure, modernize EAS overall, and potentially save lives.”

DAS, however, argues that the NAB Petition's “inferred focus on [Sage's] specific legacy technology should not be taken to suggest a broader industry challenge, whether that be in terms of supply chain, product availability, or capabilities to serve modern advanced air chain requirements.” To that end, DAS argues that “[m]odern EAS encoder/decoder systems . . . have already adapted to the requirements of contemporary broadcast facilities . . . [and] do not face the same integration challenges that may affect older or end-of-life devices.” DAS argues “[i]f, as the Petition suggests, certain EAS Participants are encountering operational friction due to outdated EAS infrastructure or legacy EAS workflows, that should be addressed through narrowly tailored policy mechanisms—such as limited waivers, technical guidance, or updates to certification criteria—rather than a sweeping rule change.” DAS also asserts “[i]n the absence of continuing demand for hardware-based EAS systems, manufacturers may redirect their resources away from research and development (R&D) for physical equipment[,]” thus potentially “stifling

innovation in areas such as hardware security, system resilience, and compatibility with new standards (
e.g.,
ATSC 3.0).”

We seek comment on these views. Is there reason to believe that EAS software solutions would not be affected by supply chain shortages that would affect manufacturers of stand-alone encoder/decoder devices generally? What impacts would EAS software solutions have on the market for EAS encoder/decoder solutions? We observe that the equipment certification requirements we seek comment on (below) are intended to ensure regulatory parity between EAS software and stand-alone EAS encoder/decoder devices. With that in mind, should we take into account the competitive impacts, if any, that EAS software might have on the production or continued development of stand-alone EAS encoder/decoder devices?

DAS also argues that “[EAS software] developers must now account for potential IP landmines that could stall or complicate product viability.” DAS indicates it has been “made aware of several published patents and provisional patents that appear to cover key aspects of the software-based EAS model.” To that end, DAS asserts that “[u]ndisclosed intellectual property may introduce significant concerns related to policy and competition in the marketplace.” We seek comment on whether the use of EAS software would implicate any intellectual property considerations, and the extent to which those differ from any such considerations that may apply to stand-alone EAS encoder/decoder devices. Are any elements of EAS software functionality patented? If so, who holds those patents and will these patents discourage or prevent vendors from entering the EAS software market and creating competition?

EAS Software Certification.
At the outset, we tentatively agree with commenters that EAS software must be subject to a rigorous certification or other approval process before it can be allowed to be marketed and used. As DAS observes, “[w]ithout such a framework, software solutions could vary significantly in quality, security, and functionality, with no clear method for regulators or users to determine compliance,” adding that such result would “dilute the integrity of the EAS ecosystem and impose an untenable oversight burden on the Commission.” We seek comment on what certification or other approval framework should apply to EAS software.

The EAS rules currently require dedicated EAS equipment to be certified in accordance with the Commission's equipment certification procedures in part 2 of the Commission's rules. While § 11.34(a) and (b), 47 CFR 11.34(a), (b), covering encoders and decoders, respectively, require demonstration of compliance with the requirements in part 11 and the requirements in the part 15 rules for digital devices, we do not propose to extend the part 15 compliance requirement to EAS software, which we anticipate will be installed in various off-the-shelf and custom equipment of other manufacturers that already will have competed any applicable FCC equipment authorization processes. Equipment certification involves device testing to ensure that the device meets the performance requirements that apply to it. Certification approval is required before that device model can be marketed. The responsible party (typically the manufacturer) for the device handles the various administrative requirements, arranges for device testing by an accredited FCC-recognized test laboratory, and submits the certification application to a telecommunication certification body (TCB), which reviews the test report and other application materials, and issues the certification on behalf of the FCC. This framework is well-established, but historically is geared towards testing and authorization of licensed and unlicensed intentional radiators (
e.g.,
broadcast transmitters, mobile handsets and garage door openers) and unintentional radiating equipment (
e.g.,
personal computers and other digital devices that emit emissions as a byproduct of their digital clock circuity) with easily measurable in-band, out-of-band and harmonic radio frequency (RF) emissions levels. Certifying or otherwise approving EAS software represents a different challenge, that may require an alternative approach.

Commenters addressing this issue generally support subjecting EAS software to certification, and generally frame their discussions around our existing equipment authorization rules and procedures. SBE, for example, comments that certification is necessary “to ensure that flexible software-based EAS solutions enjoy at least the same level of security and reliability as current dedicated hardware solutions.” DAS raises concerns that EAS software certification is necessary, but that “there is no [], widely accepted FCC process for certifying software-only EAS solutions.” We tentatively conclude that requiring EAS software to be certified under a conformity assessment scheme that is architecturally similar or identical to that under which EAS equipment is certified today is necessary to preserve the reliability of EAS,
i.e.,
EAS software would be submitted to an approved entity for testing and then to a certification body for approval. We seek comment on this view. Noting that test labs are generally focused on measuring equipment emissions, power, bandwidth, etc., are such test labs equipped with personnel and equipment to conduct detailed software testing for EAS? Are there accreditation standards that test labs would need to comply with and be approved for? If EAS software is required to be certified, how should the certification requirement be implemented? Can the existing certification framework in part 2 be applied to ensure that EAS software works correctly? Would modifications to the existing part 2 framework be necessary to support this testing? If so, what changes are needed and how would those changes fit into the current test lab and TCB approval process? Are there alternative approaches to testing and certification that achieve similar or better outcomes? For example, would some combination of the existing part 2 device certification framework and a third-party conformity assessment regime geared towards software be a suitable approach, and if so, how would those be integrated? Should the certification framework be completely independent of part 2, and if so, how should it be structured? In such a case, what types of entities have capability for such testing and approvals? Would such an entity be expected to issue certification or similar approval on the Commission's behalf, similar to the role TCBs currently have in the equipment certification process?

We seek comment on what functions should be tested and what procedures should be followed when certifying or otherwise approving EAS software. Currently, dedicated EAS equipment is tested to ensure compliance with the encoder and decoder requirements in §§ 11.32 (and § 11.31 as cross-referenced therein) and 11.33 using oscilloscopes and other radio frequency (RF) analyzing instruments, as well as compliance with some non-electrical requirements. For example, testing includes causing the encoder to generate a header code string and using an oscilloscope to confirm that the string conformed to the Audio Frequency Shift Keying modulation specifications at § 11.31(a)(1); inputting an alert to confirm storage of the audio message per § 11.33(a)(3)(i); and inputting an EAN alert while the encoder is playing

out a non-EAN alert and confirming that the EAN overrides the non-EAN alert in progress. Are the existing methods for testing compliance with these requirements sufficient to ensure compliance for both EAS hardware and software (as installed in hardware)? Sage observes that “TCBs do not check for most elements of EAS processing,” adding “we need (and have always needed) a set of tests similar to the 2011 FEMA Conformity Assessment.” Regardless of what certification regime EAS software or hardware might be certified or otherwise approved under, are there specific aspects of alert processing or other part 11 functionalities that are not currently tested as part of the FCC's EAS equipment certification process, but should be, and if so, what testing procedures should apply? Given the potential for widespread variety in EAS software configurations, should the Commission or independent standards bodies develop a more comprehensive test procedure for EAS equipment and EAS software? Should the IPAWS Conformity Assessment's pass/fail testing approach be applied to EAS software, and if so, should it be applied as-is or as modified in some way? Could that approach be updated and standardized to cover not just CAP-to-legacy conversion, but any other alert processing functionalities that are not currently tested but should be? What additional functionalities should be included? Who should develop such a standard? Would a reconstituted ECIG or other industry group be best-positioned to develop such standard? Are there certain testing requirements or procedures that should be different for EAS equipment and EAS software to reflect their differing characteristics, or should EAS equipment and EAS software always be subject to the same requirements and procedures? Are TCBs equipped to perform testing on EAS software following the pass/fail approach used for testing compliance with the ECIG Implementation Guide? If not, what entities are best suited to perform such testing, and what accreditation scheme, if any, should apply? Are there existing third-party testing programs that could accommodate such testing?

We observe that several requirements in the Commission's EAS encoder and decoder rule sections set forth physical and electrical specifications that apply to the hardware aspects of the equipment, as well as the emissions profile of the radiofrequency signals they generate. Sage notes, for example, that “[p]art 11 requires an alphanumeric display, a speaker, visual indication of alert status, `data ports', two or more audio inputs, and one or more audio outputs,” adding that “requirements for temperature and humidity, supply voltage variations, and operation in 10 V/m AM and 0.5 V/m FM [also] must be met.” Sage further observes, “[a]s a practical matter, this requires a separate box for certification.” At the time these and other encoder and decoder requirements were developed in the early 1990s, it was assumed that these functions would be performed in a stand-alone device built for this purpose. Does this assumption still make sense today, given the current state of technology? Do these requirements still make sense as applied to either EAS software or standalone equipment built for EAS purposes? We seek comment on whether any or all of the physical and electrical specifications that apply to the hardware aspects of dedicated EAS equipment should be applied to EAS software, as installed whichever representative configuration applies (
e.g.,
the off-the-shelf server in which the EAS software is installed). We observe that application of some of these requirements to EAS software can be achieved through minor revisions to some of these provisions, as contained in Appendix B of this Further Notice. We seek comment on the sufficiency of these proposed revisions.

With respect to how the EAS software must be configured for testing, we propose that EAS software must be tested as installed in hardware that is representative of that which it is intended and marketed to be used. As a result, the certification that EAS software would receive would apply only to that EAS software as installed and operated in a representative server or computer configuration. Pursuant to this approach, standalone EAS software that is intended to be installed and operated in an off-the-shelf server or computer would be tested as installed by the software manufacturer in any representative server or computer. EAS software that is intended to be installed and operated in a manufacturer's custom-designed product—for example, a signal processing system component that performs one or more signal processing functions and may include a central processing unit (CPU) utilizing custom or generic operating system software, but which is not itself a stand-alone server or computer—would have to be tested as installed in such custom-designed component, since there is no representative device for such a custom-designed product. In this case, the manufacturer of the custom-designed product typically would be responsible for certification, and the EAS software certification testing would be performed at the same time as the custom-designed product's conformity assessment testing. More specifically, the EAS software certification would be a component of and subsumed under the custom-designed product's certification. EAS software that is installed and integrated across multiple system components would have to be tested as so installed and integrated (typically on an in situ basis). Because this also is a custom configuration, the manufacturer of the system components typically would be responsible for certification. We observe that the representative testing model proposed above is currently applied to most device testing under our equipment authorization rules because it is neither practical nor necessary to test each and every device produced in a product model line manufactured for sale to the public. We seek comment on whether this would be an effective testing framework for EAS software. Are there any unique applications or considerations involving EAS software that might not be accounted for under this framework? Are there any alternatives methods to this representative testing approach we should consider? Commenters that offer alternatives should comment on benefits and burdens for EAS software vendors, EAS Participants, and Commissions staff.

We also seek comment on whether and which modifications to certified EAS software should require recertification. If we were to apply the part 2 certification framework to EAS software, § 2.1043 of the Commission's rules delineates the types of modifications (or permissive changes) that manufacturers can make to previously certified equipment without requiring equipment recertification. The permissive change rules primarily apply to changes involving electrical and RF circuitry, but include provisions covering changes to software installed in software-defined radios (SDR), which are treated as Class III permissive changes. These provisions trigger where the software modification “changes the frequency range, modulation type or maximum output power (either radiated or conducted) outside the parameters previously approved, or that change the circumstances under which the transmitter operates in accordance with Commission rules.” We seek comment on whether, regardless of what equipment certification or approval framework might be applied to EAS

software, a similar approach makes sense for EAS software, and what modifications, if any, to EAS software—and by extension, EAS performance—should require resubmission of certification information (test data, etc.) as the equivalent to a Class II permissive change. We also seek comment on whether software is sufficiently different from physical hardware that it should require a periodic recertification throughout its life cycle, which would represent a fundamentally different approach from the current equipment authorization model. We note that, unlike a physical device that may never be modified, software is typically updated many times, and users sometimes continue to run software after it is no longer supported by the vendor. Updates may address critical and necessary security issues that emerge after initial approval, but such updates can unintentionally disrupt system functions and introduce new and unexpected faults. The use of software that is no longer supported can introduce functional and cybersecurity risks. Parties who support such an approach should discuss how a periodic reapproval process could be implemented, as well as what procedures we might adopt for automatically cancelling certification or approval when software is not recertified within the required time interval. If a certification or approval is automatically cancelled for software, what responsibilities should fall on the developer to notify impacted users and regulatory bodies? Additionally, what actions should be taken to ensure that system integrity and reliability are maintained during and after this process?

Cybersecurity.
We acknowledge concerns raised by commenters responding to the NAB Petition regarding potential risks that EAS software may pose to EAS security. DAS, for example, observes that “[s]oftware systems—especially network-dependent platforms—tend to be far more exposed to cybersecurity threats than standalone hardware.” DAS further observes that “[u]nlike physical devices, software platforms have large attack surfaces, including APIs, databases, and remote access points.” Sage acknowledges that “[c]ybersecurity is an issue that needs to be taken into account,” but disagrees that EAS software poses a unique risk, stating that “the issues are known, and are not fundamentally different than any other IT component of a broadcast facility.” Cybersecurity is plainly a cause for concern in the EAS environment, as exemplified by the many hacking incidents that have resulted in false alerts, and in the process, prevented the transmission of legitimate, lifesaving alerts, documented in the Report and Order. We tentatively agree with the Broadcast Warning Working Group that uniformity in EAS performance, regulatory certainty, and overall EAS security are critical to any EAS software configuration. We also tentatively agree with DAS that “[a]s the digital landscape continues to evolve, ensuring the security and integrity of systems involved in the EAS becomes increasingly vital.” We seek comment on these views.

Accordingly, we propose that, before EAS software can be marketed or used, the responsible party seeking its certification should be required to demonstrate to the Commission that it has taken appropriate steps to secure the software. We seek comment on the most effective way in which we can implement this requirement. Should a Declaration of Conformity with specific standards or best practices, a cybersecurity audit or test report, or other evidence be required to be included in the EAS software's certification application? (In general, a Declaration of Conformity is an attestation from the responsible party that the equipment or software has been shown to comply with the applicable technical standards and other applicable requirements of the conformity assessment regime against which it is being issued.) If so, what specific cybersecurity criteria should the software satisfy? We observe that there are several existing cybersecurity certification programs for software, each with different focuses. Would a certification from one of these programs be best suited to demonstrating the cybersecurity of EAS software? For example, would one or more of the National Information Assurance Partnership's (NIAP) Approved Protection Profiles provide such a set of standards or would an additional profile for EAS software be needed, either alone or in combination with existing profiles? If a new profile is required, how should it be developed, and how long would it take to develop? Additionally, should we require vendors of EAS software to participate in CISA's Secure by Design program? Would cybersecurity certification of EAS software alone be sufficient to ensure the cybersecurity of the EAS, taken together with the cybersecurity requirements we adopt today? If we were to adopt cybersecurity requirements for EAS software, should we also impose cybersecurity requirements on standalone EAS equipment on a going-forward basis in order to ensure parity? If so, should the cybersecurity criteria for equipment be different than software? Should foreign-produced EAS software be subject to importation and use prohibitions where national security is implicated, for example, where the software designer, manufacturer, or responsible party for certification is on the Covered List?

DAS asserts that EAS software will shift many of the responsibilities for implementing secure hardware configurations, maintaining firmware integrity, performing vulnerability testing, and ensuring end-to-end system hardening, which standalone EAS equipment manufacturers handle today, onto EAS Participants, “many of whom may lack the technical expertise or resources to manage them effectively.” We seek comment on this view. Does the successful use and maintenance of EAS software require EAS Participants to have more technical and cybersecurity expertise than when using standalone EAS equipment? Do EAS Participants generally have this expertise, or will the use of EAS software by the average EAS Participant introduce serious risks to EAS's performance? Are there any characteristics or features that EAS software should be required to reduce the level of expertise that the EAS Participant would need to have in order to use it successfully? Should we limit the use of EAS software only to certain EAS Participants, and if so, how would EAS Participants demonstrate that they qualify to use it?

Operational Readiness.
We propose to lessen the time that would be afforded to EAS Participants to repair or replace defective EAS software before notifying the Commission from 60 days to 72 hours. Under the current rules, EAS Participants may operate without defective equipment pending its repair or replacement for 60 days without further FCC authority. We observe that 60 days is an amount of time that in most cases may be sufficient for manual repair and shipping of defective equipment to and from the manufacturer. As noted above, however, the record indicates that one of EAS software's main benefits is that it can be expeditiously repaired with rapid fail-over to backup EAS software in an auxiliary location. As the NAB Petition states, “maintenance of a station's EAS system and the time needed to recover from a hardware component malfunction would be greatly reduced because a system repair could now be implemented through a software update,

patch, or other remote fix, eliminating the down-time needed to ship the legacy physical device to a manufacturer for factory repair.” Based on the record, we believe that EAS software is unlikely to be defective for very long and in many cases, EAS can continue to be provided by backup EAS software. In addition, we believe that EAS software may be more prone to cyberattack by virtue of its IP interconnectedness. Accordingly, there is a heightened need for Commission awareness of lingering EAS software defects that may derive from ransomware, viruses, or other cyberattacks. For these reasons, we tentatively conclude that 72 hours is a reasonable amount of time for an EAS Participant using EAS software to either effectuate repairs or switch over to backup EAS software to ensure EAS is still available until repairs of the EAS software in its main facility are completed. We seek comment on these views. Is 72 hours a reasonable amount of time to complete repairs of defective EAS software? Should this amount of time be lowered or increased, and why? What impact would providing more or less time have on the Commission's situational awareness about the state of EAS operational readiness nationwide?

We invite commenters to recommend any additional or alternative requirements, changes, or limitations that may be needed to enable the Commission to assure EAS stakeholders and the public that EAS software can reliably meet or exceed all existing EAS operational requirements. Are the requirements we propose today sufficient, overall, to ensure EAS software meets or exceeds the reliability, security, and availability provided by current EAS equipment? If changes to the overall certification and cybersecurity framework for EAS software about which we seek comment above would be beneficial, how should the Commission implement them? Commenters that offer alternatives should comment on benefits and burdens for EAS software vendors, EAS Participants, and Commissions staff.

We previously observed that, according to the Bureau's last nationwide EAS test report, an appreciable number of EAS Participants were unable to participate in testing due to equipment failure—despite advance notice that such test was to take place—suggesting that equipment failures are not addressed by EAS Participants as swiftly as reasonably possible and that more needs to be done to improve EAS operational readiness. As discussed above, we believe that allowing the use of EAS Software could expedite repairs. Would allowing the use of EAS software also have an effect on the average amount of time needed to repair dedicated EAS devices? For example, would the entry of EAS software into the market reduce the number of EAS devices that need to be repaired at any given time, improve the availability of vendors' repair teams, and therefore reduce wait times and repair speed? If so, should we modify our operational readiness rules for dedicated EAS devices to reflect that less repair time is needed?

Finally, we observe that § 11.35(c) currently requires EAS Participants who require more than 60 days to repair or replace defective EAS equipment to submit an informal request for additional time to the Regional Director of the FCC field office serving the area in which the EAS Participant is located, or in the case of DBS and SDARS providers, to the Regional Director of the FCC field of
