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.
