FCC Rejects SpaceX and Iridium Bids to Rewrite “Big LEO” Spectrum Rules as Direct-to-Cell Race Heats Up

The FCC delivered a rare rebuke to SpaceX on April 23, 2026. Five satellite operators’ bids to rewrite Big LEO spectrum rules were dismissed — a decision shaping the pace and density of low-Earth orbit expansion for years to come.

The ruling matters beyond the telecom industry. Spectrum policy is the upstream regulator of LEO traffic. Which frequencies get assigned determines which constellations launch at scale, how many satellites they deploy, and at what altitude they operate. That, in turn, determines how crowded the orbital environment becomes — and how large the debris risk grows.

What the FCC Actually Did

The FCC’s Wireless Telecommunications Bureau dismissed multiple petitions in a single order covering three spectrum bands:

  • Big LEO bands (1610–1626.5 MHz and 2483.5–2500 MHz): SpaceX and Iridium had sought rulemakings that would have opened these frequencies — currently reserved for Globalstar — to new entrants or expanded use. The FCC rejected both petitions. “We find both petitions unconvincing,” the agency wrote. “Neither has presented a sufficient basis to disturb the longstanding certainty and stability of the spectrum plan for Big LEO systems.”
  • 2 GHz MSS band: AST SpaceMobile and Sateliot had asked to share this band, which EchoStar currently occupies exclusively. The FCC denied both requests, reaffirming that the band can support only one operator to prevent harmful interference with direct-to-cell service.
  • L-band (1525–1660.5 MHz): SpaceX had sought access for both its Starlink broadband service and its planned direct-to-cell constellation. The FCC rejected those requests as well, citing interference risks to Ligado’s existing licensed operations.

The practical effect: incumbents Globalstar and Iridium keep their exclusive footholds. Newer entrants — Kepler, Sateliot, and to a degree SpaceX in these specific bands — are told to stay in their lane.

SpaceX Loses the Battle, Not the War

The ruling is a setback for SpaceX, but a targeted one. Starlink’s existing operations in its licensed bands are unaffected. More significantly, SpaceX is acquiring EchoStar’s 2 GHz spectrum — the very band denied to it in Thursday’s order. If that acquisition clears FCC approval, SpaceX would gain rights to build a 15,000-satellite direct-to-cell constellation in the 2 GHz band without needing a rulemaking.

Satellite industry analyst Tim Farrar of TMF Associates summarized the FCC’s posture bluntly: “This new FCC order is super complicated, but basically is telling everyone to stay in their lane.”

FCC Chairman Brendan Carr framed the decision as pro-investment clarity, not a brake on competition. “The FCC is laser-focused this year on making our rules as friendly as possible for investment and innovation in D2D services,” Carr said in a statement. His stated goal: at least three facilities-based providers competing in the satellite direct-to-device space — a market structure the rulings are designed to support.

The LEO Congestion Angle

For FODNews readers tracking orbital debris risk, this ruling is a regulatory data point — incremental but meaningful.

The direct-to-cell race is driving an unprecedented expansion of LEO satellite counts. SpaceX alone has proposed a 15,000-satellite constellation for the 2 GHz band. AST SpaceMobile received FCC approval for 248 satellites on April 22, the day before this ruling. The constellation will provide direct-to-cell service using AT&T and Verizon spectrum. Amazon, which is acquiring Globalstar for $11 billion, is positioning to compete with its own LEO direct-to-cell capability.

Thursday’s ruling preserves existing spectrum boundaries but does not slow the overall expansion of LEO infrastructure. It simply routes growth through established regulatory channels — incumbent licenses and acquisition — rather than new rulemaking. The net effect on orbital congestion is incremental: SpaceX’s Big LEO ambition is blocked for now, but the EchoStar pathway remains open. AST SpaceMobile’s 248-satellite build continues. Amazon-Globalstar advances.

As FODNews has reported, Starlink’s existing constellation generated nine conjunction threats in a single March 2026 week. That volume illustrates how current satellite densities are already stressing orbital traffic management. Spectrum policy decisions like this one — which shape how many next-generation satellites get built and where — feed directly into that trajectory.

What Comes Next

The FCC signaled it is not done reshaping the D2D market. Carr indicated the agency would vote later in April on increasing allowed power levels for LEO satellites in certain bands. SpaceX has advocated for that change to improve Starlink performance.

SpaceX’s EchoStar 2 GHz acquisition still requires FCC sign-off. That proceeding — not the dismissed petitions — is now the primary regulatory venue for Starlink’s next wave of direct-to-cell expansion.

For the orbital debris community, the calculus is straightforward: each new mega-constellation approved adds satellites to an already crowded environment. Thursday’s ruling delays one potential growth vector. It does not reverse the trajectory.
