The FCC released a notice of proposed rulemaking on sharing between satellite services -- including nongeostationary satellite orbit (NGSO) and geostationary satellite orbit (GSO) fixed satellite service (FSS) operations -- and 3 other services -- fixed services (FS), broadcast auxiliary services (BAS) and cable TV relay services (CARS). The final rules would apply in the 7 GHz, 10 GHz and 13 GHz bands, the Commission said: “We undertake this proceeding to facilitate the introduction of new satellite and terrestrial services while promoting interference protection among the various users in these bands.” The Commission proposed the following: (1) NGSO FSS downlink operations sharing with FS operations in the 10 GHz band based on a Growth Zone Proposal by SkyBridge/Fixed Wireless Communications Coalition (FWCC). It suggested identifying FS growth zones based on geographic areas where “FS use is high and growth is most likely to occur.” The Commission’s proposal would qualify counties as growth zones “where at least 30 FS frequencies are licensed to transmit in the 10.7-11.7 GHz band.” Zone determinations would be made individually, rather than every 6 months, as NGSO FSS earth station applications were submitted to provide a “near real- time” element to the process, the FCC said. Coordination also would adopt proposals determining where the earth stations should be located, who would be protected from interference and how coordination would be determined. (2) Coordination between NGSO and GSO FSS earth stations and mobile BAS and CARS operations in the 6875-7075 MHz and 12750-13250 MHz bands. The Commission said it would apply existing coordination rules from Parts 25 and 101 of its rules to the bands and consider additions or modifications. It said it also would determine whether additional rules needed to be applied separately to FSS coordination with mobile or fixed BAS/CARS operations.
