Modernizing Spectrum Sharing for Satellite Broadband
Key claim: The FCC replaces 1990s-era Equivalent Power Flux Density limits for GSO/NGSO spectrum sharing with modern, performance-based protection criteria and a good-faith coordination framework to enable faster satellite broadband, especially in rural areas.
Abstract
(Rule · Federal Communications Commission) In this document, the Federal Communications Commission (Commission or we) adopts a Report and Order (Order) that revises the spectrum sharing framework for Geostationary Orbit (GSO) and Non- Geostationary Orbit (NGSO) systems that currently relies on NGSO systems complying with Equivalent Power Flux Density (EPFD) limits developed in the late-1990s. The consequence today of applying such EPFD limits in the United States is that operators must overprotect GSO systems, which in turn means that American households and businesses-- most critically in rural and remote areas–do not receive the fastest space-based NGSO satellite broadband American innovation has available. Based on the technical record in this proceeding, the Order replaces the EPFD framework with modern, performance-based GSO protection criteria. The Order extends the Commission’s framework for good-faith coordination and allow NGSO and GSO operators to bargain for appropriate interference protections through voluntary, private agreement. The Order further adopts technical backstops to protect GSO systems when coordination has not been reached.
Why this matters
EPFD limits set in the late 1990s have been a binding constraint on how much capacity non-geostationary constellations (e.g., Starlink, Kuiper, OneWeb) can deliver without triggering interference-protection tripwires for legacy GSO operators. Shifting to performance-based criteria plus a coordination framework changes the operational envelope for satellite broadband and is particularly consequential for rural service, where satellite is often the only viable option. For carriers it alters the competitive landscape between GSO incumbents and NGSO entrants; for consumers it is aimed at faster, higher-capacity service.
