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
-
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.
-
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.
-
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.''
-
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
-
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.
-
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.
-
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.
-
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.
-
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
-
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.
-
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.
-
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.
-
Unlicensed Hearing Assistance Devices. Resound filedcomments 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
-
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
-
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
-
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
-
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
-
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
-
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
-
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
-
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
-
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
-
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).

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.

Summary of Significant Issues Raised by the Comments in Response to the IRFA
No comments were filedin response to the IRFA.

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.

\4\ See A Guide to the Regulatory Flexibility Act, U.S. Small 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.

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.
-
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.
