Dedicated Short Range Communications of Intelligent

Transportation Services

AGENCY: Federal Communications Commission.

ACTION: Final rule.

-----------------------------------------------------------------------

SUMMARY: This document allocates 75 megahertz of spectrum at 5.850-

5.925 GHz to the mobile service for use by Dedicated Short Range

Communications (``DSRC'') systems operating in the Intelligent

Transportation System (``ITS'') radio service. ITS services are

expected to improve traveler safety, decrease traffic congestion,

facilitate the reduction of air pollution, and help to conserve vital

fossil fuels. DSRC systems are being designed that require a short

range wireless link to transfer information between vehicles and

roadside systems. We are also adopting basic technical rules

establishing power limits, and unwanted emission limits for DSRC

operations. These decisions will further the goals of the United States

(``U.S.'') Congress and the Department of Transportation (``DOT'') to

improve the efficiency of the Nation's transportation infrastructure

and will facilitate the growth and development of the ITS industry.

Summary of the Report and Order

1. By this action, the Commission allocates 75 megahertz spectrum

at 5.850-5.925 GHz to the mobile service for use by Dedicated Short

Range Communications (``DSRC'') systems operating in the Intelligent

Transportation System (``ITS'') radio service. ITS services are

expected to improve traveler safety, decrease traffic congestion,

facilitate the reduction of air pollution, and help to conserve vital

fossil fuels. DSRC systems are being designed that require a short

range wireless link to transfer information between vehicles and

roadside systems. We are also adopting basic technical rules

establishing power limits and unwanted emission limits for DSRC

operations. The R&O defers consideration of licensing and service rules

and spectrum channelization plans to a later proceeding because

standards addressing such matters are still under development by the

Department of Transportation. Once such standards are developed, the

Commission could take whatever action is necessary to implement the

standards related to DSRC use. The decisions made here will further the

goals of the U.S. Congress and the DOT to improve the efficiency of the

Nation's transportation infrastructure and will facilitate the growth

and development of the ITS industry.

2. On June 11, 1998, the Commission released the Notice of Proposed

Rule Making (``NPRM'') in ET Docket No. 98-95, 63 FR 35558, June 30,

1998, which proposed to allocate the 5.85-5.925 GHz band on a primary

basis to the mobile service for use by DSRC-based ITS operations. ITS

applications rely upon the integration of advanced communications

systems and highway infrastructure systems. Communications are an

essential component of the backbone of all ITS applications, which rely

on the swift and accurate flow of information. While many ITS

communications requirements are being met within the framework of

existing telecommunications systems, the NPRM stated that there is a

need for spectrum for reliable short-range wireless communications

links between vehicles traveling at highway speeds and roadside

systems, i.e., DSRC. Accordingly, the Commission proposed an allocation

of 75 megahertz of spectrum near 5.9 GHz for DSRC operations and

requested comment on various related matters.

3. On June 9, 1998, the President signed the Transportation Equity

Act for the 21st Century. Section 5206(f) of this Act states that

``[t]he Federal Communications Commission shall consider, in

consultation with the Secretary of Transportation, spectrum needs for

the operation of intelligent transportation systems, including spectrum

for the dedicated short-range vehicle-to-wayside wireless standard. Not

later than January 1, 2000, the Federal Communications Commission shall

have completed a rule making considering the allocation of spectrum for

intelligent transportation systems.''

4. The R&O recognizes the substantial efforts by both Government

and non-Government entities to develop, in response to Congress'

transportation legislation, a National ITS Plan and Architecture

addressing ways of using communications technologies to increase the

efficiency of the nation's transportation infrastructure. While some

parties argue that other spectrum may be more appropriate for DSRC

operations, the Commission found that the 5.85-5.925 GHz band can

accommodate a wide variety of reliable DSRC applications without

significantly hindering other users of this spectrum.

Spectrum Allocation

5. Domestically, the entire 5.850-5.925 GHz band is currently

allocated on a co-primary basis for the Government's Radiolocation

Service (i.e., for use by high-powered military radar systems) and for

non-Government Fixed Satellite Service (``FSS'') uplink operations.

Industrial, Scientific and Medical (``ISM'') devices and unlicensed

part 15 devices are also permitted to operate in the 5.850-5.875 GHz

segment. Finally, the Amateur radio service has a secondary domestic

allocation in the entire band.

6. The R&O concludes that the 5.9 GHz range is appropriate for DSRC

applications due to its potential compatibility with European and Asian

DSRC developments, the availability of radio technology, signal

propagation characteristics, and the available spectral capacity in

this spectrum range. After carefully reviewing the record, we conclude

that an allocation of spectrum in the 5.9 GHz region is the best

available choice for DSRC applications. The record also demonstrates

that the propagation characteristics of this region of the spectrum are

well suited to the short range comunications of up to a mile that will

typify DSRC operations. The ITS community has done research showing

that the 5.85-5.925 GHz frequency band provides adequate range for DSRC

[[Page 66406]]

communications and reasonable frequency reuse distances.

7. First, we note that DSRC applications are a key element in

meeting the nation's transportation needs into the next century and in

improving the safety of our nation's highways. The record submitted for

DSRC deployment in the U.S. indicates a need for up to 32 different

DSRC transactions, many of which will require two-way capabilities,

wideband channels, and the need for multiple channels in a single

location. We also note that not all channels will be available for DSRC

deployment in all areas due to incumbent radar, ISM and FSS operations.

Therefore, we find that 75 megahertz of DSRC spectrum within the United

States is warranted due to the scope of the National ITS Architecture,

the incumbent operations in this band in the U.S. and consideration

DSRC developments domestically and internationally.

8. The R&O also addresses, ITS compatibility issues with Canada and

Mexico and concludes that our allocation is sufficient to promise

interoperability with Canadian ITS developments. While discussions with

Mexico are on-going, the Commission does not anticipate spectrum

sharing problems with operations in Mexico. As service rules are

developed and operations in these bands are more clearly defined, the

need to develop coordination requirements in border areas will be

considered. Nevertheless, the R&O encourages any entities addressing

standards for ITS operations in the 5.9 GHz range to plan DSRC

applications with the least potential for interference with Canadian

operations for the 5.875-5.883 GHz and 5.908-5.925 GHz bands.

9. The R&O concludes that the 5.85-5.925 GHz band is appropriate

for DSRC-based ITS applications due to the variety of operations to be

accommodated, the propagation characteristics of the band, the

significant efforts of the Federal and state governments paired with

industry to research ITS use in this band, and ITS developments

internationally. Accordingly, the R&O allocates the 5.850-5.925 GHz

band on a primary basis to the mobile service for use by DSRC-based ITS

operations. In order to insure that mobile operations in this range are

ITS related, the item adopts footnote NG160 to the Table of Frequency

Allocations to read as follows:

NG160: In the 5850-5925 MHz band, the use of the non-Federal

government mobile service is limited to Dedicated Short Range

Communications operating in the Intelligent Transportation System

radio service.

Spectrum Sharing

10. Government Radar Operations. The National Telecommunications

and Information Administration (``NTIA'') urges the Commission to

require DSRC operations within 75 kilometers of 65 possible radar

locations to coordinate their operations through the Frequency

Assignment Subcommittee of the Interdepartment Radio Advisory Committee

(``IRAC''). DOT provides a study that indicates that DSRC operations

could operate in close proximity to most high powered Government radar

operations. The R&O concludes that sharing between DSRC and Government

operations is possible if proper coordination is performed, and thus

adopts the NTIA recommendation. Further, DSRC applications within these

coordination areas cannot claim protection from existing radar

operations, but new radar installations that may be deployed subsequent

to DSRC implementation would have to coordinate with incumbent DSRC

operations.

11. FSS Operations. The R&O finds that DSRC applications would be

compatible with FSS uplinks because FSS earth stations typically use

highly directional antennas pointed towards the geostationary orbital

arc, and DSRC applications would typically be pointed towards a highway

and operate at relatively low power. It may be necessary in some cases

for DSRC systems to avoid an area near an incumbent FSS earth station

in order to avoid the high powered earth station transmission.

Nonetheless, because of the limited number of FSS earth stations and

their use of highly directional antennas, the R&O finds that spectrum

sharing is feasible. At this time, the Commission does not anticipate

that prior coordination is necessary between DSRC and FSS operations.

12. Amateur Service Operations. The R&O concludes that DSRC

operations in the 5.85-5.925 GHz band are unlikely to receive

significant interference from or cause interference to amateur

operations. Further, the R&O notes that amateur operations are

secondary in this spectrum range. The R&O does not anticipate that a

formal coordination procedure will be necessary because amateur

operations are not extensively deployed, and due to the availability of

interference remedies if they occur. The R&O encourage any ITS entities

wishing to use the 5.85-5.925 GHz band to informally notify the ARRL or

the local amateur service community of its intended operation.

13. Unlicensed Hearing Assistance Devices. Resound filed comments

stating that it is contemplating development of unlicensed low power

hearing assistance devices in the 5.85-5.875 GHz band under the FCC's

Part 15 rules. Even if the Commission were to preclude DSRC operations

in the 5.85-5.875 GHz segment, the incumbent operations in this band

already pose a significant interference environment for hearing

assistance devices. The R&O recognizes that Resound's hearing

assistance devices could be beneficial and encourage them to identify

other spectrum that may be more appropriate for these devices.

Technical Requirements

14. The Secretary of Transportation submitted, in satisfaction of

the June 1, 1999 statutory requirement, a report to Congress

identifying which standards are critical to national interoperability

or standards development and specifying the status of the development

of each standard identified. The R&O concludes that it would be

beneficial at this time to adopt basic technical requirements to

promote spectrum sharing and create a basic framework for the

development of DSRC operational standards by industry. The Commission

recognizes that the rules it adopts here may need to be reviewed at a

later time as it develops licensing and service rules for DSRC systems.

Spectrum Channelization

15. The R&O finds that a spectrum channelization plan would

facilitate the efficient use of this spectrum and interoperability

among various DSRC services. However, the record here is insufficient

to devise a specific channel plan that would adequately address the

spectrum requirements, both narrowband and broadband, of the various

potential DSRC applications. This action invites the ITS industry and

the DOT to consider the spectrum requirements of various DSRC

applications and recommend a spectrum channel plan. The Commission will

address this matter further in a future proceeding proposing licensing

and service rules.

Power

16. The Commission finds that it is important to establish some

power limits for DSRC operations so that they can achieve widespread

deployment, and typically power requirements need to be flexible enough

to allow various DSRC applications to be developed. Most DSRC

operations will use highly directional antennas to focus communications

in an intended

[[Page 66407]]

direction (e.g., along the lane of a highway) and to promote frequency

reuse. Therefore, the Commission has adopted the following power

requirements for DSRC operations in the 5.85-5.925 GHz band:

The peak transmit output power over the frequency band of

operations shall not exceed 750 mW or 28.8 dBm with up to 16 dBi in

antenna gain. If transmitting antennas of directional gain greater

than 16 dBi are used, the peak transmit output power shall be

reduced by the amount in dB that the directional gain of the antenna

exceeds 16 dBi, i.e., the device's maximum EIRP shall not exceed 30

W EIRP. However, the peak transmitter output power may be increased

to account for any line losses due to long transmission cables

between the transmitter and the DSRC device's antenna, provided the

EIRP does not exceed 30 W.

The Commission finds that this power limit is sufficient to satisfy

many DSRC applications, compensate for transmission line losses,

promote the deployment of various types of applications, and provide a

high degree of frequency reuse. Nonetheless, the rules will require ITS

licensees to use the minimal power necessary to achieve reliable

communications in order to promote frequency reuse.

Unwanted Emission Limits

17. The R&O states that it is necessary to limit the amount of

unwanted emissions, both those occurring outside of the DSRC spectrum

band and those emanating from one channel to the next within the DSRC

band. The unwanted emission limits proposed are appropriate and

necessary to promote spectrum sharing between DSRC applications in the

5.85-5.925 GHz band. Accordingly, the Commission adopts the emission

mask requirements of Sec. 90.210(k) for DSRC operations in the 5.9 GHz

band. The R&O recognizes that depending on the developing DSRC

applications, the licensing scheme adopted and the corresponding

spectrum channelization plan, the Commission may need to revisit the

emission limits between specific channels or applications, e.g., more

sensitive applications on specific channels may require additional

protection or a licensee with access to multiple consecutive channels

in a geographic area could benefit from additional flexibility

regarding unwanted emissions without affecting other operations.

Frequency Stability

18. The Commission proposed to apply to DSRC operations in the 5.9

GHz band the frequency stability requirement specified in Sec. 2.995

(Sec. 2.1055) of our rules in order to prevent DSRC operations from

causing interference to DSRC operations on other channels or to other

services in nearby spectrum. However, part 90 has more specific

frequency stability requirements in Sec. 90.213 which vary according to

the channel bandwidth of the operation. Since the R&O is not yet able

to establish a channelization plan for DSRC operations, the Commission

defers any decision on frequency stability requirements to a future

proceeding.

RF Guidelines

19. The Commission requires compliance with RF safety guidelines

for all applications to ensure the public's safety. Therefore, DSRC

operations must comply with the RF safety guidelines contained in the

Second Memorandum Opinion and Order (``Second MO&O'') in ET Docket No.

93-62, 62 FR 47960, September 12, 1997. The R&O finds that this level

of protection is appropriate and will not result in exposure to the

public of unsafe levels of RF energy.

Unlicensed DSRC Operations

20. Section 15.245 of the Commission's rules permits unlicensed

field disturbance sensors to operate in the 5.785-5.815 GHz band. While

these field disturbance sensors are not available for two-way

information communications, the rules would permit backscatter type

toll-tag operations in this band with a permitted average field

strength of 500 millivolts/meter at a distance of 3 meters (75 mW

EIRP). Additionally, Sec. 15.247 of the rules permits unlicensed spread

spectrum communications devices to operate in the 5.725-5.850 GHz band

with a maximum peak transmitter output power of 1 watt with antenna

gain of up to 6 dBi. Finally, Sec. 15.249 permits unlicensed

communications devices to operate in the 5.725-5.875 GHz band with a

maximum average field strength of 50 millivolts/meter at a distance of

3 meters (0.8 mW EIRP

21. The R&O finds that a backscatter system that transmits an

unmodulated carrier signal to a mobile transponder which, in turn,

reflects a modulated signal, does not qualify as a conventional spread

spectrum system under the part 15 rules. Part 15 defines a spread

spectrum system as a system that conveys information by modulation of a

carrier by some conventional means and then deliberately widens the

bandwidth by means of a spreading function over that which would be

needed to transmit the information alone. Because backscatter beacon

stations do not modulate their carriers, they do not qualify as spread

spectrum devices. The R&O declines to modify the rules to allow

backscatter systems to qualify for use as spread spectrum systems under

Sec. 15.247. Nevertheless, the spread spectrum requirements of

Sec. 15.247 can likely accommodate a wide range of alternative

unlicensed DSRC communication systems.

Other Issues

22. The Commission adopts the following definition of DSRC services

for this mobile allocation in the 5.9 GHz range:

The use of non-voice radio techniques to transfer data over

short distances between roadside and mobile radio units, between

mobile units, and between portable and mobile units to perform

operations related to the improvement of traffic flow, traffic

safety and other intelligent transportation service applications in

a variety of public and commercial environments. DSRC systems may

also transmit status and instructional messages related to the units

involved.

Final Regulatory Flexibility Analysis

23. As required by the Regulatory Flexibility Act (``RFA''),\1\ an

Initial Regulatory Flexibility Analysis (``IRFA'') was incorporated

into the Notice of Proposed Rule Making (``NPRM'') in ET Docket No. 98-

95, 63 FR 35558, June 30, 1998. The Commission sought written comment

on the proposals in the NPRM, including the IRFA. The Final Regulatory

Flexibility Analysis (``FRFA'') in this Report and Order conforms to

the RFA.\2\

---------------------------------------------------------------------------

\1\ See 5 U.S.C. 603. The RFA, see 5 U.S.C. 601 et seq., has

been amended by the Contract With America Advancement Act of 1996,

Public Law 104-121, 110 Stat. 847 (1996) (CWAAA). Title II of the

CWAAA is the Small Business Regulatory Enforcement Fairness Act of

1996 (SBREFA).

\2\ See 5 U.S.C. 604.

---------------------------------------------------------------------------

A. Need for and Objective of This Report and Order (R&O).

This R&O allocates the 5.850-5.925 GHz band to the Private Land

Mobile Service (``PLMS'') for use by Dedicated Short Range

Communications Services (``DSRCS'') in the provision of Intelligent

Transportation Services (``ITS''). DSRCS communications are used for

non-voice wireless transfer of data over short distances between

roadside and mobile radio units, between mobile units, and between

portable and mobile units to perform operations related to the

improvement of traffic flow, traffic safety and other intelligent

transportation service applications in a variety of public and

commercial environments. The objective of this action is to provide

sufficient spectrum to permit the development of DSRCS technologies to

[[Page 66408]]

improve the Nation's transportation infrastructure and bolster the

involvement of United States companies in this emerging industry. While

this R&O does adopt an allocation and some basic technical parameters,

the issues of licensing, channelization, and other complex technical

matters are being deferred to a later proceeding. Therefore, because

this present action will not result in the provision of these

operations, the IRFA certified that the NPRM would not have a

significant economic impact on a substantial number of small entities.

Nevertheless, a full voluntary IRFA was performed. No comments directly

addressed the IRFA.

B. Summary of Significant Issues Raised by the Comments in Response to

the IRFA

No comments were filed in response to the IRFA.

C. Description and Estimate of the Number of Small Entities to Which

the Rules Will Apply

Under the RFA, small entities may include small organizations,

small businesses, and small governmental jurisdictions.\3\ The RFA, 5

U.S.C. 601(3), generally defines the term ``small business'' as having

the same meaning as the term ``small business concern'' under the Small

Business Act, 15 U.S.C. 632. A small business concern is one which: (1)

is independently owned and operated; (2) is not dominant in its field

of operation; and (3) satisfies any additional criteria established by

the Small Business Administration (``SBA''). This standard also applies

in determining whether an entity is a small business for purposes of

the RFA. The 5.85-5.925 GHz band is currently available to the U.S.

Federal Government for Radiolocation purposes, Fixed Satellite Service

licensees for international intercontinental links, amateur radio

operators and by various entities using part 18 Industrial, Scientific

and Medical (``ISM'') equipment and part 15 unlicensed device

equipment. We note that there are only 45 Fixed Satellite Service

(``FSS'') licenses issued for operation in 5.85-5.925 GHz band and most

if not all are held by large corporations. Further, amateur radio

operators and the Federal Government do not qualify as small entities.

We also note that part 18 ISM devices are protected in this band, which

only generate electromagnetic energy, are not used for communication

purposes and therefore cannot receive interference or be impacted by

this action. Finally, while part 15 unlicensed devices are permitted to

operate in the 5.85-5.875 GHz portion, they do so on an unlicensed,

unprotected basis. Further, the Commission has no means to determine

the number of small entities that might use unlicensed part 15

equipment that operates in the band at issue. SBA guidelines to the

Small Business Regulatory Enforcement Fairness Act (``SBREFA'') state

that about 99.7% of all firms are small and have fewer than 500

employees and less than $25 million in sales and assets.\4\ There are

approximately 6.3 million establishments in the SBA database.\5\ The

R&O discusses means by which the potential DSRCS would be able to share

the spectrum with incumbent operations and concludes that harmful

interference can be avoided through coordination. Accordingly, we do

not believe this action would have a negative impact on small entities

that operate in the 5.85-5.925 GHz band.

Business Administration, Washington, DC, May 1996, at page 14.

\5\ Id. at 15.

---------------------------------------------------------------------------

Regarding the Fixed Satellite Service licensees for international

intercontinental links, the Commission has not developed a definition

of small entities applicable to licensees in the international

services. Therefore, the applicable definition of small entity is

generally the definition under the SBA rules applicable to

Communications Services, Not Elsewhere Classified (NEC).\6\ This

definition provides that a small entity is expressed as one with $11.0

million or less in annual receipts.\7\ According to the Census Bureau,

there were a total of 848 communications services providers, NEC, in

operation in 1992, and a total of 775 had annual receipts of less than

$9,999 million.\8\ The Census report does not provide more precise

data. Regarding the future use of the 5.85-5.925 GHz band by DSRCS

equipment, we believe it is too early to make an determination on such

operations. A future rule making proceeding will propose further

technical standards, licensing and service rules and a separate

regulatory flexibility analysis will address all issues relevant to

that proceeding.

D. Description of Projected Reporting, Record Keeping and Other

Compliance Requirements

In this proceeding, we are allocating this spectrum for a new

service. The licensing and technical regulations governing these

operations will be addressed in a separate proceeding. Therefore, this

action does not create any reporting or compliance requirements.

E. Steps Taken To Minimize Significant Economic Impact on Small

Entities, and Significant Alternatives Considered

The IRFA in this proceeding requested comment on ways to minimize

economic impact on small entities, but no comments were filed.

Nevertheless, the attached R&O discusses whether operational standards

should be adopted to facilitate nation-wide interoperability of DSRCS,

but deferred this issue to a later proceeding that will develop service

rules for these operations. The development of DSRCS operational

standards could delay the initial deployment of such equipment, but

could ultimately result in equal footing for all manufacturers,

including small entities, in producing equipment that meets uniform

standards.

F. Report to Congress

This Commission will send a copy of the R&O, including this FRFA,

in a report to be sent to Congress pursuant to the Small Business

Regulatory Enforcement Fairness Act of 1996, see U.S.C. 801(a)(1)(A).

In addition, the Commission will send a copy of the R&O, including

FRFA, to the Chief Counsel for Advocacy of the Small Business

Administration.

7. Section 90.350 is revised to read as follows:

Sec. 90.350 Scope.

The Intelligent Transportation Systems radio service is for the

purpose of integrating radio-based technologies into the nation's

transportation infrastructure and to develop and implement the nation's

intelligent transportation systems. It includes the Location and

Monitoring Service (LMS) and Dedicated Short Range Communications

Service (DSRCS). Rules as to eligibility for licensing, frequencies

available, and any special requirements for services in the Intelligent

Transportation Systems radio service are set forth in this subpart.

8. A new Sec. 90.371 is added to subpart M to read as follows:

Sec. 90.371 Dedicated short range communications service.

(a) These provisions pertain to systems in the dedicated short

range communications services (DSRCS). DSRCS systems utilize non-voice

radio techniques to transfer data over short distances between roadside

and mobile radio units, between mobile units, and between portable and

mobile units to perform operations related to the improvement of

traffic flow, traffic safety and other intelligent transportation

service applications in a variety of public and commercial

environments. When authorized, DSRCS licensees operating systems in the

5850-5925 MHz band may serve individuals, federal government agencies

and entities eligible for licensing in this Part, and must comply with

the following requirements.

(b) DSRCS stations operating in the band 5850-5925 MHz shall not

receive protection from Government Radiolocation services in operation

prior to the establishment of the DSRCS station. Operation of DSRCS

stations within 75 kilometers of the locations listed in the table

below must be coordinated through the National Telecommunications and

Information Administration.
