USA - Modernizing Spectrum Sharing for Satellite Broadband

The FCC final rule revises the spectrum-sharing framework between Geostationary Orbit (GSO) and Non-Geostationary Orbit (NGSO) satellite systems.

Framework updated: The FCC replaces the older Equivalent Power Flux Density (EPFD) limits, developed in the late 1990s, with modern, performance-based criteria for protecting GSO systems.

Reason for change: The FCC states that the existing EPFD framework can overprotect GSO systems and limit the performance of NGSO satellite broadband services, especially for rural and remote users.

Coordination approach: The rule extends the FCC’s good-faith coordination framework, allowing NGSO and GSO operators to negotiate interference protections through voluntary private agreements.

Technical safeguards: The FCC adopts technical backstops to protect GSO systems when coordination agreements are not reached.
