FCC Set to Vote on Direct-to-Device Spectrum Auction, Opening Door to Satellite-Mobile Rivals

The US Federal Communications Commission will vote on a direct-to-device (D2D) spectrum auction, a move that would clear regulatory ground for satellite operators seeking to compete with terrestrial mobile carriers.

The vote, if approved, would allocate spectrum specifically for satellite-to-cellular services, letting operators beam connectivity directly to standard mobile phones. The step marks a shift in how the FCC treats airwaves historically reserved for terrestrial mobile use.

What direct-to-device means

D2D, also called satellite-to-cell or direct-to-cell, refers to technology that lets ordinary smartphones connect to satellites without dedicated hardware. Unlike legacy satphones, D2D handsets use the same chipsets and antennas as standard 4G and 5G devices.

The approach has drawn investment from satellite operators including AST SpaceMobile, SpaceX's Starlink unit, and Lynk Global, all pursuing low-Earth-orbit (LEO) constellations aimed at mobile coverage. T-Mobile US has already struck a partnership with SpaceX for direct-to-cell testing, while other carriers have signed similar arrangements.

Why the FCC vote matters

US spectrum remains allocated primarily to terrestrial mobile carriers. The proposed D2D auction would mark the Commission's first move to formally designate airwaves for satellite-mobile service, easing a long-standing regulatory bottleneck.

The vote signals that the FCC intends to treat D2D as a separate service category rather than an adjunct feature of terrestrial networks. That distinction matters for licensing terms, interference management, and how operators plan their networks.

Stakes for incumbents

AT&T and Verizon hold large mid-band 5G portfolios that have not been earmarked for satellite use. Analysts expect both operators to scrutinize the auction terms, given that competing D2D service could erode their coverage edge in rural and remote markets.

The Commission has framed its D2D work as part of a broader push to extend connectivity in underserved areas, an argument that has political backing across agencies focused on rural broadband.

Market context

Commercial D2D service has progressed through partnerships that blur the line between satellite and mobile operators. AST SpaceMobile has launched its first commercial satellites and signed agreements with AT&T and Verizon. SpaceX and T-Mobile began testing direct-to-cell service in 2024.

Both companies frame D2D as complementary to terrestrial networks rather than competitive, an argument the FCC appears to be weighing as it shapes the auction.

What comes next

The Commission's vote will set the auction timetable, the eligible bands, and the build-out obligations attached to any license won. Analysts expect the FCC to issue a Notice of Proposed Rulemaking or Report and Order in the months following the vote.

The outcome will shape how quickly satellite-mobile service reaches US consumers and how it sits alongside incumbent carrier networks.
