On Friday, the FCC issued a reminder to all operators “of fixed-satellite service (FSS) earth stations in the 3.7-4.2 GHz band that were constructed and operational as of April 19, 2018 that the filing window to license or register such earth stations closes on October 17, 2018.” This frequency band is commonly referred to as the “C-Band”, and many of the “FSS earth stations” are satellite dishes that receive programming used by both radio and TV stations. The FCC is exploring allowing additional users into this spectrum, and has warned that only registered users of the spectrum will be entitled to any protections against any new users who may be authorized. In Friday’s public notice, the FCC also noted that those being protected not only need to have been operating by April 19 and registered by October 17 to be protected, but those entities will need to certify that the information in their registrations is correct on a form that will be made available at some point in the future. Users who have already registered are urged to make sure that their registrations are accurate by October 17, as certain corrections will not be allowed after that date. So broadcasters using this spectrum to receive satellite-delivered programming should heed the FCC’s advice and register by October 17.
