The FCC has announced a temporary freeze, beginning April 19, 2018, on the filing of new or modification applications for fixed-satellite service earth station licenses, receive-only earth station registrations, and fixed microwave licenses in the 3.7 - 4.2 GHz band. Also, beginning April 19, 2018, there is a 90-day window during which entities that own or operate existing FSS earth stations in the 3.7 - 4.2 GHz band may file an application to register or license the earth station if it is currently not registered or licensed.
