Satellite Spectrum Sharing (GSO/NGSO EPFD Framework Modernization)
Current understanding
To be populated as evidence accumulates.
Evidence log
- 2026-11-05 — Modernizing Spectrum Sharing for Satellite Broadband: cross-connection with satellite-broadband-spectrum-sharing: The updated geostationary reference links concern the same GSO/NGSO spectrum-sharing interface addressed by the EPFD framework page, without establishing that this action changes EPFD limits. (novelty: 2)
- 2026-10-26 — Space Modernization for the 21st Century: cross-connection with fcc-space-modernization: Space modernization proceeding overlaps with GSO/NGSO spectrum sharing framework updates. (novelty: 2)
- 2026-09-08 — Unleashing Unlicensed Spectrum for Direct-to-Device: cross-connection with unlicensed-spectrum-direct-to-device: Both concern FCC frameworks for satellite spectrum access; the unlicensed D2D NPRM extends satellite use into bands historically governed by terrestrial unlicensed rules, complementing GSO/NGSO sharing modernization. (novelty: 3)
- 2026-07-31 — Upper C-Band (3.98-4.2 GHz); Expanding Flexible Use of the 3.7 to 4.2 GHz Band: cross-connection with upper-c-band-flexible-use-3980-4200-mhz: FSS incumbents in 3.98–4.2 GHz must be migrated (with costs shifted to terrestrial licensees), continuing the C-band satellite-to-terrestrial transition pattern. (novelty: 3)
- 2026-04-21 — Mystic Alerts Act: cross-connection with wireless-emergency-alerts-satellite: Satellite WEA delivery would rely on satellite operators and spectrum coordination frameworks governed under GSO/NGSO sharing rules. (novelty: 3)
- 2026-05-13 — Modernizing Spectrum Sharing for Satellite Broadband: FCC Report and Order replaces 1990s-era Equivalent Power Flux Density (EPFD) limits with performance-based GSO protection criteria and a good-faith NGSO/GSO coordination framework, intended to unlock additional satellite broadband capacity for rural and remote users.
