Satellite, Wireless Interest Clash Over FSS in 51 GHz
Satellite interests backed and wireless interests opposed a Satellite Industry Association call for a fixed satellite service (FSS) allocation in the 51.4-52.4 GHz band, in FCC comments Tuesday in RM-11871. Many satellite operators are developing networks and systems that would…

operate using feeder links in the V band, Boeing said in support of SIA. "Immediate action ... is warranted" since a global FSS allocation in the spectrum adopted at the 2019 World Radiocommunication Conference took effect Jan. 1, Boeing said. Amazon's Kuiper said a proposed rulemaking should be expanded to allow non-geostationary use of the spectrum, as well as geostationary, instead of initiating a second NPRM for NGSO use. NGSO and GSO providers can maximize their feeder link operations with access to the 51 GHz spectrum, it said. Hughes said the swath is domestically allocated as a shared federal and nonfederal band for terrestrial fixed and mobile wireless services, but it's largely unused by federal and nonfederal services. But CTIA said access to high-band airwaves is a major part of the U.S. 5G strategy, and the availability of such "is already heavily imbalanced towards satellite use." It said SIA's effort would "forestall steady progress that the U.S. has made in identifying and licensing high-band spectrum for mobile terrestrial use." SIA's petition said FSS in 51 GHz can share with other services while protecting passive services in adjacent bands.
