The Federal Communications Commission has revised its satellite spectrum-sharing rules Jessica Rosenworcel said the satellite spectrum sharing rules update “allows first movers to enjoy the advantage they’ve earned by daring to think big and take on risk, while also opening our skies to more competition.” Satellite Spectrum Interference Protection The new rules adopt a 3 percent time-weighted average throughput degradation as a long-term interference protection criterion and a 0.4 percent absolute increase in link unavailability as a short-term interference protection criterion. While Amazon’s Kuiper, Viasat, Telesat, Intelsat and SpaceX agreed to the long-term interference protection criterion, OneWeb opposed it and submitted a petition for reconsideration, which the FCC denied. The agency also declined to adopt additional protection metrics or an aggregate limit on interference from later-round NGSO FSS systems into earlier-round systems. Recent Posts
