FCC Expands Band Focus of Recently Adopted Satcom FNPRM
The 51.4-52.4 GHz band is currently allocated domestically for fixed and mobile services, but there's robust evidence supporting its use for satellite communications, the FCC said Tuesday as it released the satellite spectrum Further NPRM adopted at its May 22…

meeting (see 2505220056). The draft FNPRM was limited to asking about opening the 12.7 and 42 GHz bands to satcom. The adopted version added the 51.4-52.4 GHz, 92-94 GHz, 94.1-100 GHz, 102-109.5 GHz and 111.8-114.25 GHz bands. It also asks about creating a domestic fixed satellite service allocation in the 52.14-52.4 GHz allocation; whether that allocation's use should be limited to non-geostationary orbit (NGSO) satellites; and whether limits on unwanted power emissions could ensure NGSO compatibility with space research operations in the nearby 52.6-54.25 GHz band. In addition, it seeks comment on whether any satellite use of the 92.0-94.0 GHz, 94.1-100 GHz, 102.0-109.5 GHz and 111.8-114.25 GHz bands should be limited to gateway unlinks for NGSO systems, as well as about the possibility of extending the self-coordinated and data-assisted “light-licensing” framework for the 70/80/90 GHz band to those W-band frequencies.
