The Federal Communications Commission is preparing to vote on a major overhaul of satellite spectrum-sharing rules that could significantly increase the capacity and performance of space-based broadband services.
Brendan Carr announced that the proposed order would replace a regulatory framework dating back to the 1990s, enabling up to sevenfold increases in capacity and generating more than $2 billion in projected economic benefits. The changes focus on how Geostationary Orbit (GSO) and Non-Geostationary Orbit (NGSO) satellite systems share spectrum, reflecting advances in satellite technology, including adaptive coding and modulation (ACM).
Under the proposal, the FCC would move away from the legacy Equivalent Power Flux Density (EPFD) limits, which historically constrained NGSO systems to protect GSO satellites. In their place, the Commission would adopt performance-based protection criteria and continue to rely on coordination agreements between operators. The FCC argues that the existing EPFD rules, based on outdated system assumptions, have limited the ability of modern NGSO constellations to deliver high-speed, low-latency broadband—particularly in underserved and rural areas.
- FCC plans to vote on updated satellite spectrum-sharing rules at its next monthly meeting
- Proposal targets replacement of EPFD limits with performance-based GSO protection criteria
- Expected impact includes up to 7x increase in satellite broadband capacity
- Projected economic benefit exceeds $2 billion
- New framework supports voluntary coordination between GSO and NGSO operators
- Advances such as adaptive coding and modulation (ACM) underpin the updated model
“The FCC is moving fast to unleash affordable, high-speed Internet,” said Carr. “By discarding last century’s satellite regulations, we could see billions of dollars in benefits for the American economy and broadband speeds many times faster than what is available today.”
🌐 Analysis: The FCC’s proposed shift away from EPFD marks a structural change in how satellite interference is managed, effectively aligning regulatory policy with the capabilities of modern NGSO constellations such as those deployed by SpaceX (Starlink) and Amazon (Project Kuiper). By emphasizing performance-based criteria and negotiated coordination, the Commission is signaling a more flexible, market-driven approach to spectrum management.
🌐 Analysis: This move also reflects broader momentum in space-based broadband, where increasing demand for low-latency connectivity is driving rapid constellation deployment and investment. If adopted, the rule changes could reduce satellite count requirements, improve spectral efficiency, and intensify competition with terrestrial broadband providers, particularly in rural and hard-to-reach regions.
