FCC Clears More Downlink Spectrum for Satellite Internet Services Like Starlink

Key Points:

• The FCC has approved expanded access to the 12.7-13.25GHz and 42-42.5GHz radio bands for fixed satellite services like Starlink, allowing both uplink and downlink use and benefiting applications including in-motion use on planes and boats.
• The decision unlocks an additional 525 megahertz of contiguous downlink spectrum, potentially accelerating broadband deployment in rural and remote areas by increasing capacity by over 25%.
• The 42GHz spectrum is authorized for downlinking at ground-based gateway stations, which is expected to improve satellite ground network traffic routing and increase capacity by 7.2% for high-throughput, low-orbit satellites.
• FCC Chairman Brendan Carr highlighted that the increased spectrum will enhance bandwidth for consumer terminals, making satellite broadband faster, more reliable, and more competitive with traditional ISPs.
• The FCC also exempted satellite constellations from federal environmental reviews, facilitating SpaceX’s plans to expand Starlink’s satellite network despite concerns from astronomers and environmentalists about space debris and light pollution.
