FCC Seeing Calls for Edits to NGSO/GSO Spectrum Sharing NRPM
Updating the spectrum sharing framework between geostationary orbit (GSO) and non-geostationary orbit (NGSO) satellite systems now, instead of waiting for pending international proceedings, would get Americans enhanced satellite broadband faster, SpaceX and Telesat said Tuesday (docket 25-157). They suggested changes to the draft NPRM regarding GSO/NGSO sharing in the 10.7-12.7, 17.3-18.6 and 19.7-20.2 GHz bands on the FCC's April meeting agenda (see 2504070054). Those changes included proposing that current GSO protections ultimately sunset so NGSO systems aren't unduly limited. The companies also called for the NPRM to propose backstop short-term and long-term interference protection criteria.

In a video call with an aide to FCC Chairman Brendan Carr, New America's Open Technology Institute and Public Knowledge said an update to the sharing rules is overdue. The groups also urged a sunset of GSO protections in the name of not inhibiting competition. They said the FCC should adopt a degraded throughput methodology as the interference protection criteria, and the NPRM should tentatively conclude that the FCC will adopt a default sharing mechanism that lets NGSO systems operate at a minimum avoidance angle from operational GSO satellites in the GSO arc. The FCC is also seeing lobbying regarding the 37 GHz draft order (see 2504220011) and the caller ID authentication gap NPRM (see 2504220013) on Monday's meeting agenda.
