  § 27.73   WCS, AMT, and Goldstone coordination requirements.

   This section requires Wireless Communications Services (WCS) licensees in
   the 2305-2320 MHz and 2345-2360 MHz bands, respectively, to coordinate the
   deployment  of base and fixed stations (except fixed customer premises
   equipment) with the Goldstone, CA Deep Space Network (DSN) facility in the
   2290-2300 MHz band and 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 and DSN facilities.

   (a) WCS licensees operating base and fixed stations in the 2345-2360 MHz
   band  must,  prior  to  operation of such stations, achieve a mutually
   satisfactory coordination agreement with the AMT entity(ies) (i.e., FCC
   licensee(s) and/or Federal operator(s)) for any AMT receiver facility within
   45 kilometers or radio line of sight, whichever distance is larger, of the
   intended  WCS  base or fixed station location. The coordinator for the
   assignment of flight test frequencies in the 2360-2390 MHz band, Aerospace
   and Flight Test Radio Coordination Council (AFTRCC) or successors of AFTRCC,
   will facilitate a mutually satisfactory coordination agreement between the
   WCS licensee(s) and AMT entity(ies) for existing AMT receiver sites. The
   locations of current Federal and non-Federal AMT receiver sites may be
   obtained from AFTRCC at Post Office Box 12822 Wichita, KS 67277-2822, (316)
   946-8826, or successor frequency coordinators of AFTRCC. Such coordination
   agreement  shall  provide protection to existing AMT receiver stations
   consistent with International Telecommunication Union (ITU) Recommendation
   ITU-R M.1459, “Protection criteria for telemetry systems in the aeronautical
   mobile  service  and  mitigation techniques to facilitate sharing with
   geostationary broadcasting-satellite and mobile-satellite services in the
   frequency bands 1 452-1 525 MHz and 2 310-2 360 MHz May 2000 edition,”
   adopted May 2000, as adjusted using generally accepted engineering practices
   and  standards to take into account the local conditions and operating
   characteristics of the applicable AMT and WCS facilities. This ITU document
   is incorporated by reference in accordance with 5 U.S.C. 552(a) and 1 CFR
   part 51 and approved by the Director of Federal Register. Copies of the
   recommendation may be obtained from ITU, Place des Nations, 1211 Geneva 20,
   Switzerland, or online at
   http://www.itu.int/en/publications/Pages/default.aspx. You may inspect a
   copy  at  the  Federal Communications Commission, 445 12th Street SW.,
   Washington, DC 20554, or at the National Archives and Records Administration
   (NARA). For information on the availability of this material at NARA, call
   202-741-6030,     or     go    to:    http://www/archives.gov/federal_
   register/code_of_federal_regulations/ibr_locations.html.

   (b) WCS licensees operating base and fixed stations in the 2305-2320 MHz
   band  must,  prior  to  operation of such 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 (35°25′33″ N, 116°53′23″ W).

   (c) After base or fixed 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.
