  §  27.73   WCS, AMT, and Goldstone coordination requirements.

   This section requires Wireless Communications Services (WCS) licensees
   in the 2345-2360 MHz band to coordinate the deployment of base stations
   with Aeronautical Mobile Telemetry (AMT) facilities in the 2360-2395
   MHz band; and to take all practicable steps necessary to minimize the
   risk of harmful interference to AMT facilities.

   (a) Wireless Communications Service (WCS) licensees operating base
   stations in the 2345-2360 MHz band shall, prior to operation of such
   base stations, achieve a mutually satisfactory coordination agreement
   with the Aerospace and Flight Test Radio Coordinating Council (AFTRCC)
   for any AMT receiver facility within 45 kilometers or the radio line of
   sight, whichever distance is larger, of the intended WCS base station
   location. This coordination is necessary to protect AMT receive systems
   consistent with Recommendation ITU-R M.1459. The locations of the
   current and planned Federal and non-Federal AMT receiver sites may be
   obtained from AFTRCC.

   (b) WCS licensees operating base stations in the 2305-2320 MHz band
   shall, prior to operation of such base stations, achieve a mutually
   satisfactory coordination agreement with the National Aeronautics and
   Space Administration (NASA) within 145 kilometers of the Goldstone, CA
   earth station site (35DEG25'33" N, 116DEG53'23" W).

   (c) After base station operations commence, upon receipt of a complaint
   of harmful interference, the WCS licensee(s) receiving the complaint,
   no matter the distance from the NASA Goldstone, CA earth station or
   from an AMT site, operating in the 2305-2320 or 2345-2360 MHz bands,
   respectively, shall take all practicable steps to immediately eliminate
   the interference.

   (d) Duty to cooperate. WCS licensees, AFTRCC, and NASA must cooperate
   in good faith in the coordination and deployment of new facilities. WCS
   licensees must also cooperate in good faith in the selection and use of
   new station sites and new frequencies when within radio line of site of
   AMT receiver facilities to reduce the risk of harmful interference and
   make the most effective use of the authorized facilities. Licensees of
   stations suffering or causing harmful interference must cooperate in
   good faith and resolve such problems by mutually satisfactory
   arrangements. If the licensees are unable to do so, the Wireless
   Telecommunications Bureau, in consultation with the Office of
   Engineering and Technology and the National Telecommunications and
   Information Administration may impose restrictions including specifying
   the transmitter power, antenna height, or area or hours of operation of
   the stations.
