§  90.371   Dedicated short range communications service.

   (a) These provisions pertain to systems in the 5850-5925 MHz band for
   Dedicated Short-Range Communications Service (DSRCS). DSRCS systems use
   radio techniques to transfer data over short distances between roadside
   and mobile 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 environments. DSRCS systems may also
   transmit status and instructional messages related to the units
   involved. DSRCS Roadside Units are authorized under this part. DSRCS
   On-Board Units are authorized under part 95 of this chapter.

   (b) DSRCS Roadside Units (RSUs) 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 RSU stations within the radius centered on the locations listed
   in the table below must be coordinated through the National
   Telecommunications and Information Administration.

   (c) NTIA may authorize additional station assignments in the federal
   radiolocation service and may amend, modify, or revoke existing or
   additional assignments for such service. Once a federal assignment
   action is taken, the Commission's Universal Licensing System database
   will be updated accordingly and the list in paragraph (b) of this
   section will be updated as soon as practicable.
