SpaceX's 800 MHz Deal Is a Tower Deal
SpaceX's Grain spectrum will run on towers and rooftops, not satellites. Why that makes American Tower, Crown Castle and SBA the deal's early winners.
SpaceX’s 800 MHz Deal Is a Tower Deal
SpaceX’s agreed purchase of Grain Management’s 800 megahertz licenses comes with Federal Communications Commission construction deadlines, and for terrestrial deployment SpaceX’s own filing describes radios on towers and rooftops. So far the companies with the most to gain own the towers.
Up to 14 MHz
Paired low-band spectrum nationwide in the Grain portfolio, and less in some counties.

First construction benchmark: 33 percent of each license’s population or 25 percent of its geography.

Tower leases SpaceX has announced for the 800 megahertz network.
SpaceX’s purchase of Grain Management’s 800 megahertz (MHz) spectrum is, on the evidence so far, more a deal for towers than for satellites. The licenses SpaceX agreed to buy on 8 October come with Federal Communications Commission (FCC) construction deadlines, and for terrestrial deployment SpaceX’s own filing describes radios on towers, rooftops and other structures (company-stated). SpaceX has kept a satellite option open as well, but the FCC has not yet cleared the band for satellite use, LightShed Partners doubts SpaceX will put the band on its satellites, and New Street Research notes it does not work with SpaceX’s current direct-to-device satellites. The companies with the most to gain so far are the ones that own the towers: American Tower, Crown Castle and SBA Communications.
Why did tower stocks rise on a satellite company’s spectrum deal?
Low-band spectrum such as 800 MHz needs large antennas, which suits towers far better than satellites built in volume. To use the spectrum and meet the FCC’s deadlines, SpaceX has to build or rent a terrestrial network, and much of that means renting space from American Tower, Crown Castle and SBA Communications, alongside independent tower owners and rooftops. The FCC still has to approve the transfer of Grain’s licenses to SpaceX, and SpaceX has not signed a tower lease.
