Modernizing EPFD constraints could increase satellite broadband capacity by up to 180 percent by allowing more intensive spectrum use.

The FCC has initiated Part 100 rulemaking to replace the existing Part 25 framework for a modular licensing process for modern mega-constellations.

Further decisions regarding spectrum sharing and the implementation of the Build America agenda are expected as the FCC coordinates with the National Telecommunications and Information Administration (NTIA).

The FCC processed 3,418 applications during its 2025 Space Month initiatives, a 21 percent increase over the previous year.

The policy adjustment is part of a 2025 year-end review aimed at enhancing satellite-to-smartphone connectivity.

Federal Communications Commission (FCC) Chairman Brendan Carr confirmed the adoption of new regulatory frameworks allowing satellite operators to use higher power levels for direct-to-cell (D2C) services on December 23.

The FCC's year-end report stated that regulatory friction is being systematically removed from its interaction with the commercial space sector.

The FCC harmonized rules for Mobile-Satellite Service (MSS) spectrum, providing nearly 20,000 megahertz of bandwidth for satellite broadband.

The FCC completed the regulatory clearance of SES's acquisition of Intelsat, a $3.1 billion transaction that established a combined fleet of approximately 120 satellites across geostationary (GEO) and medium Earth orbits (MEO).

SpaceX filed to expand its Starlink constellation with 15,000 additional satellites in very low Earth orbit (VLEO) to provide ubiquitous D2C connectivity.

The policy review includes a modification of Equivalent Power Flux Density (EPFD) limits to prevent low Earth orbit (LEO) systems from interfering with GEO incumbents.

Filament-winding with carbon fiber has been established practice for payload adapters for a long time.

The filament-wound process produces a monolithic component without any machining or adhesive bonding of separate parts.

The component is filament-wound with carbon fiber onto a mandrel in multiple layers.
