SpaceX announced an agreement on October 8, 2026, to acquire Grain Management’s nationwide U.S. low-band spectrum portfolio for Starlink Mobile. The reported portfolio covers the 800 MHz band and includes up to 14 MHz of paired spectrum. As of October 9, the transfer remained subject to Federal Communications Commission (FCC) approval and other closing conditions.
What SpaceX agreed to acquire
The agreement concerns spectrum licenses across the United States. Spectrum is the radio-frequency capacity wireless networks use to carry signals. The portfolio is described as low-band spectrum in the 800 MHz band, with up to 14 MHz paired—two frequency ranges used together for communication.
The figure is an upper limit, not a claim that the portfolio contains exactly 14 MHz. And while the licenses have nationwide scope, that describes the spectrum portfolio, not Starlink Mobile service already reaching customers across the country.
How the spectrum could support Starlink Mobile
SpaceX says the spectrum, combined with its Gen2 satellite constellation, could help Starlink become a major U.S. mobile carrier. The proposed approach brings together satellite-to-mobile connectivity and a terrestrial network. Lower-band spectrum may also help signals travel through obstacles and support indoor coverage, a potential benefit of the planned network.
Those goals give the spectrum a role beyond adding capacity: it could help SpaceX build a hybrid mobile network. The agreement itself, however, is a step toward that plan, not a description of a service launch.
FCC approval and the next step
As of October 9, the proposed license transfer still required FCC approval and other closing conditions. An FCC proposal published on October 8 addressed possible auctions in the 1675–1695 MHz and 2020–2025 MHz bands, a separate regulatory matter from the SpaceX–Grain Management agreement.
The agreement’s announced purpose is to support SpaceX’s U.S. mobile ambitions; the transfer remained contingent on regulatory approval and the other closing conditions.
