SUPPLEMENTARY INFORMATION:

This is a summary of the Federal Communications Commission's Memorandum Opinion and Order, FCC 06-110, adopted July 20, 2006 and released on July 26, 2006. The full text of this document is available for inspection and copying during normal business hours in the FCC Reference Center, 445 12th Street, SW., Washington, DC 20554. The complete text may be purchased from the Commission's copy contractor, Best Copy and Printing, Inc., 445 12th Street, SW., Room CY-B402, Washington, DC 20554. The full text may also be downloaded at: http://www.fcc.gov. Alternative formats are available to persons with disabilities by contacting Brian Millin at (202) 418-7426 or TTY (202) 418-7365 or at Brian.Millin@fcc.gov.

1. In the Memorandum Opinion and Order, the Commission takes the following actions:

  • Designates Channel 172 (frequencies 5.855-5.865 GHz) exclusively for vehicle-to-vehicle safety communications for accident avoidance and mitigation, and safety of life and property applications; and designate Channel 184 (frequencies 5.915-5.925 GHz) exclusively for high-power, longer-distance communications to be used for public safety applications involving safety of life and property, including road intersection collision mitigation.
  • Requires licensees to file a notice of construction with the Commission for each site registered and to clarify that site priority attaches to prior registered sites that have been fully constructed within the requisite twelve-month construction period.
  • Amends the power reduction rule to only apply to DSRC Roadside Unit antenna height only between eight and fifteen meters, thereby providing increased flexibility and reduced implementation costs.
  • Declines to adopt rules that would implement a software-based prior frequency coordination protocol that directs or recommends that licensees use particular service channels, or that would establish a third party database manager to coordinate and maintain site registrations.
  • Declines to amend the current emission mask applicable to DSRC Class D devices, pending further developments and recommendations from the ASTM E17.51 DSRC Standards Writing Group.
  • Declines to adopt rules governing frequency coordination between DSRC licensees and Fixed Satellite Service (FSS) licensees, pending results of studies of interference methodology and ongoing industry discussions.
  • Declines to adopt a rule establishing a separate class of On-Board Units to be used exclusively by public safety eligibles, i.e., “public safety OBUs.”
  • Declines to require dual-band DSRC devices to be uniquely identified in order to be used to provide DSRC services in the 5.9 GHz band.

I. Procedural Matters

A. Paperwork Reduction Act

2. The order does not contain any new or modified information collection.

B. Report to Congress

3. The Commission will send a copy of this Memorandum Opinion and Order in a report to be sent to Congress and the General Accounting Office pursuant to the Congressional Review Act, see 5 U.S.C. 801(a)(1)(A).

C. Supplemental Final Regulatory Flexibility Analysis

4. As required by the Regulatory Flexibility Act (RFA), a Supplemental Final Regulatory Flexibility Analysis (FRFA) was incorporated in the DSRC Report and Order. In view of the fact that we have adopted further rule amendments in this Memorandum Opinion and Order, we have included this Supplemental Final Regulatory Flexibility Certification. This Certification conforms to the RFA.

5. The RFA requires that regulatory flexibility analysis be prepared for rulemaking proceedings unless the agency certifies that “the rule will not, if promulgated, have a significant economic impact on a substantial number of small entities.” The RFA generally defines “small entity” as having the same meaning as the term “small business,” “small organization,” and “small governmental jurisdiction.” In addition, the term “small business” has the same meaning as the term “small business concern” under the Small Business Act. 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).

6. This Memorandum Opinion and Order amends our rules to require licensees to file a notice of construction to the Commission for each site registered and clarify that site priority attaches to prior registered sites that have fully constructed within the twelve month construction period; amends the antenna height correction factor adopted for DSRC to increase flexibility and reduce implementation costs to public safety, and designates Channel 172 (5.855-5.865 GHz) for vehicle-to-vehicle safety communications for accident avoidance and mitigation, and Channel 184 (5.915-5.925 GHz) for high-power, longer-distance communications for public safety applications and road intersection vehicular collision mitigation. These rule changes are not expected to affect the cost of DSRC equipment or implementation. Therefore, we certify that the requirements of this Memorandum Opinion and Order will not have a significant economic impact on a substantial number of small entities.

7. The Commission will send a copy of the Memorandum Opinion and Order, including a copy of this final certification, in a report to Congress pursuant to the Congressional Review Act, see U.S.C. 801(a)(1)(A). In addition, the Memorandum Opinion and Order and this certification will be sent to the Chief Counsel for Advocacy of the Small Business Administration. A copy of this Memorandum Opinion and Order and (or summaries thereof) will also be published in the Federal Register.

II. Ordering Clauses

8. Pursuant to sections 1, 4(i), 302, 303(f) and (r), and 332 of the Communications Act of 1934, as amended, 47 U.S.C. 1, 154(i), 302, 303(f) and (r), and 332, this Memorandum Opinion and Order is adopted.

9. It is further ordered that, the amendments of the Commission's rules as set forth in rule changes are adopted November 6, 2006.

10. It is further ordered that the Commission's Consumer and Governmental Affairs Bureau, Reference Information Center, shall send a copy of this Memorandum Opinion and Order, including the Supplemental Final Flexibility Certification, to the Chief Counsel for Advocacy of the U.S. Small Business Administration.

Frequencies available; maximum EIRP and antenna height, and priority communications.

(a) Licensees shall transmit only the power (EIRP) needed to communicate with an OBU within the communications zone and must take steps to limit the Roadside Unit (RSU) signal within the zone to the maximum extent practicable.

(b) Frequencies available for assignment to eligible applicants within the 5850-5925 MHz band for RSUs and the maximum EIRP permitted for an RSU with an antenna height not exceeding 8 meters above the roadway bed surface are specified in the table below. Where two EIRP limits are given, the higher limit is permitted only for state or local governmental entities.

1 An RSU may employ an antenna with a height exceeding 8 meters but not exceeding 15 meters provided the EIRP specified in the table above is reduced by a factor of 20 log(Ht/8) in dB where Ht is the height of the radiation center of the antenna in meters above the roadway bed surface. The EIRP is measured as the maximum EIRP toward the horizon or horizontal, whichever is greater, of the gain associated with the main or center of the transmission beam. The RSU antenna height shall not exceed 15 meters above the roadway bed surface.
2 Channel 172 is designated for public safety applications involving safety of life and property.
3 Channel Nos. 174/176 may be combined to create a twenty megahertz channel, designated Channel No. 175. Channels 180/182 may be combined to create a twenty-megahertz channel, designated Channel No. 181.
4 Channel 184 is designated for public safety applications involving safety of life and property. Only those entities meeting the requirements of § 90.373(a) are eligible to hold an authorization to operate on this channel.

(c) Except as provided in paragraphs (d) and (e) of this section, non-reserve DSRCS channels are available on a shared basis only for use in accordance with the Commission's rules. All licensees shall cooperate in the selection and use of channels in order to reduce interference. This includes monitoring for communications in progress and any other measures as may be necessary to minimize interference. Licensees of RSUs suffering or causing harmful interference within a communications zone are expected to cooperate and resolve this problem by mutually satisfactory arrangements. If the licensees are unable to do so, the Commission may impose restrictions including specifying the transmitter power, antenna height and direction, additional filtering, or area or hours of operation of the stations concerned. Further the use of any channel at a given geographical location may be denied when, in the judgment of the Commission, its use at that location is not in the public interest; use of any such channel may be restricted as to specified geographical areas, maximum power, or such other operating conditions, contained in this part or in the station authorization.

(d) Safety/public safety priority. The following access priority governs all DSRCS operations:

(1) Communications involving the safety of life have access priority over all other DSRCS communications;

(2) Subject to a control channel priority system management strategy (see ASTM E2213-03 DSRC Standard at § 4.1.1.2(4)), DSRCS communications involving public safety have access priority over all other DSRC communications not listed in paragraph (d)(1) of this section. Roadside Units (RSUs) operated by state or local governmental entities are presumptively Start Printed Page 52750engaged in public safety priority communications.

(e) Non-priority communications. DSRCS communications not listed in paragraph (d) of this section, are non-priority communications. If a dispute arises concerning non-priority communications, the licensee of the later-registered RSU must accommodate the operation of the early registered RSU, i.e., interference protection rights are date-sensitive, based on the date that the RSU is first registered (see § 90.375) and the later-registered RSU must modify its operations to resolve the dispute in accordance with paragraph (f) of this section.

(f) Except as otherwise provided in the ASTM-DSRC Standard (see § 90.379) for the purposes of paragraph (e) of this section, objectionable interference will be considered to exist when the Commission receives a complaint and the difference in signal strength between the earlier-registered RSU and the later-registered RSU (anywhere within the earlier-registered RSU's communication zone) is 18 dB or less (co-channel). Later-registered RSUs causing objectionable interference must correct the interference immediately unless written consent is obtained from the licensee of the earlier-registered RSU.

4 Channel 184 is designated for public safety applications involving safety of life and property.

(b) Except as provided in paragraph (c) of this section, non-reserve DSRCS channels are available on a shared basis only for use in accordance with the Commission's rules. All licensees shall cooperate in the selection and use of channels in order to reduce interference. This includes monitoring for communications in progress and any other measures as may be necessary to minimize interference. Licensees suffering or causing harmful interference within a communications zone are expected to cooperate and resolve this problem by mutually satisfactory arrangements. If the licensees are unable to do so, the Commission may impose restrictions, including specifying the transmitter power, antenna height and direction, additional filtering, or area or hours of operation of the stations concerned. Further, the use of any channel at a given geographical location may be denied when, in the judgment of the Commission, its use at that location is not in the public interest; the use of any channel may be restricted as to specified geographical areas, maximum power, or such other operating conditions, contained in this part or in the station authorization.

(c) Safety/public safety priority. The following access priority governs all DSRCS operations:

(1) Communications involving the safety of life have access priority over all other DSRCS communications;

(2) Subject to a control channel priority system management strategy (see ASTM E2213-03 DSRC Standard at § 4.1.1.2(4)), DSRCS communications involving public safety have access priority over all other DSRC communications not listed in paragraph (c)(1) of this section. On-Board Units (OBUs) operated by state or local governmental entities are presumptively engaged in public safety priority communications.

(d) Non-priority communications. DSRCS communications not listed in paragraph (c) of this section, are non-priority communications. If a dispute arises concerning non-priority DSRCS-OBU communications with Roadside Units (RSUs), the provisions of § 90.377(e) and (f) of this chapter will apply. Disputes concerning non-priority DSRCS-OBU communications not associated with RSUs are governed by paragraph (b) of this section.
