World Radiocommunication Conferences Concerning Frequency Bands Above 28 MHz

This document amends our rules to implement domestically various allocation decisions from several World Radiocommunication Conferences ("WRCs") concerning the frequency bands between 28 MHz and 36 GHz, and to otherwise update our rules in this frequency range. The following actions are the most significant to non-Federal government operations: Implementation of generic mobile-satellite service ("MSS") allocations in the bands 1525-1559 MHz and 1626.5- 1660.5 MHz ("L-band"); allocation of the band 1164-1215 MHz to the radionavigation-satellite service ("RNSS"); deletion of unused and limited fixed-satellite service ("FSS") and broadcasting-satellite service ("BSS") allocations from the band 2500-2690 MHz; and upgrade of the Earth exploration-satellite service ("EESS") allocation in the band 25.5-27 GHz from secondary to primary. In addition, at the request of the National Telecommunications and Information Administration ("NTIA"), we implement various allocation changes for the space science services and the inter-satellite service ("ISS"), most of which involve spectrum primarily used by the Federal government. These actions conform our rules to previous WRC decisions and are expected to provide significant benefits to the American public.
