15  Apparatus licensed transmitters near the 900 MHz band
  Apparatus licensed aeronautical navigation services are operated in the 960 MHz to 1215 MHz frequency range, above the 900 MHz spectrum licensed band upper boundary at 960 MHz. Immediately adjacent to or near-adjacent to the 960 MHz boundary, these services are limited to the operation of distance measuring equipment (DME) and tactical air navigation (TACAN) systems. As mobile receivers operating in the upper segment of the 900 MHz band are not registered, they are not afforded any protection from aeronautical services; however, this is not expected to cause any issues because both mobile and aeronautical services have operated on either side of the 960 MHz boundary for many years.
