FCC preserves incumbent MSS rights as US D2D spectrum race grows

The FCC dismissed SpaceX, Iridium, Kepler, Sateliot, and AST SpaceMobile bids to access or expand use of Mobile Satellite Service bands in the Big LEO and 2 GHz spectrum, citing harmful interference risks and the need to protect current MSS licensees. The decision preserves incumbent rights for MSS users (including EchoStar and Globalstar) and aims to provide market certainty, even as Amazon moves to acquire Globalstar to enter the D2D market and AST SpaceMobile advances its US D2D plans with partner cellular frequencies.
