SpaceX Escalates Clash With T-Mobile Over Starlink’s Wireless Ambitions

SpaceX has accused T-Mobile and other legacy carriers of opposing proposed FCC spectrum rules out of a “misplaced desire to harm a competitor,” intensifying tensions between the two companies despite their existing Starlink partnership.
The dispute centers on proposed limits on satellite transmission power. SpaceX argues that the rules could restrict direct-to-cell coverage, while T-Mobile warns that satellite signals could interfere with its network, potentially wiping out up to 96% of a cell site's uplink coverage area and reducing uplink speeds by 88% to 99%.
The disagreement reflects a broader competition over the future of wireless connectivity. SpaceX is pursuing expanded satellite-to-phone services, while T-Mobile, AT&T, and Verizon are also investing in satellite technology to extend coverage to underserved areas.
With the FCC considering new spectrum rules, the outcome could shape Starlink's wireless ambitions and determine how far its partnership with T-Mobile can extend.
