  §  90.375   RSU license areas, communication zones and registrations

   (a) DSRCS Roadside Units (RSUs) in the 5850-5925 MHz band are licensed
   on the basis of non-exclusive geographic areas. Governmental applicants
   will be issued a geographic area license based on the geo-political
   area encompassing the legal jurisdiction of the entity. All other
   applicants will be issued a geographic area license for their proposed
   area of operation based on county(s), state(s) or nationwide.

   (b) Applicants who are approved in accordance with FCC Form 601 will be
   granted non-exclusive licenses for all non-reserved DSRCS frequencies
   (see § 90.377). Such licenses serve as a prerequisite of registering
   individual RSUs located within the licensed geographic area described
   in paragraph (a) of this section. Licensees must register each RSU in
   the Universal Licensing System (ULS) before operating such RSU. RSU
   registrations are subject, inter alia, to the requirements of § 1.923 of
   this chapter as applicable (antenna structure registration,
   environmental concerns, international coordination, and quiet zones).
   Additionally, RSUs at locations subject to NTIA coordination (see
   § 90.371(b)) may not begin operation until NTIA approval is received.
   Registrations are not effective until the Commission posts them on the
   ULS. It is the DSRCS licensee's responsibility to delete from the
   registration database any RSUs that have been discontinued.

   (c) Licensees must operate each RSU in accordance with the Commission's
   Rules and the registration data posted on the ULS for such RSU.
   Licensees must register each RSU for the smallest communication zone
   needed (for the DSRC-based intelligent transportation systems
   application) using one of the following four communication zones:
   RSU class Max. output
   (dBm)^1 Communications
   A 0 15
   B 10 100
   C 20 400
   D 28.8 1000

   ^1The ASTM-DSRC Standard is incorporated by reference in accordance
   with 5 U.S.C. 552(a) and 1 CFR part 51 and approved by The Director of
   the Federal Register. Copies may be inspected at the Federal
   Communications Commission's Reference Information Center, located at
   the address of the FCC's main office indicated in 47 CFR 0.401(a), or
   at the National Archives and Records Administration (NARA). Copies of
   the ASTM E2213-03 DSRC Standard can be obtained from ASTM
   International, 100 Barr Harbor Drive, PO Box C700, West Conshohocken,
   PA 19428-2959. Copies may also be obtained from ASTM via the Internet
   at The ASTM-DSRC Standard limits output power to
   28.8 dBm but allows more power to overcome cable losses to the antenna
   as long as the antenna input power does not exceed 28.8 dBm and the
   EIRP does not exceed 44.8 dBm. However, specific channels and
   categories of uses have additional limitations under the ASTM-DSRC
