A spectrum licence gives a mobile carrier access to radio waves. It does not, by itself, provide nationwide coverage.
That is why SpaceX is reportedly seeking access to at least 80,000 cell sites across the United States as it explores a new wireless network.
Bloomberg reported that SpaceX is in talks with cellular infrastructure companies, including Crown Castle.
The discussions could support a fourth nationwide wireless carrier. However, the talks do not confirm a lease or a launch date. SpaceX and the tower companies did not comment to Reuters.
Why a satellite company needs ground sites
SpaceX’s Starlink satellites can connect directly with compatible phones. But satellites and ground-based mobile networks serve different roles.
Satellites can extend coverage across remote areas.
In busy cities, ground sites help networks handle many users and provide more reliable service.
SpaceX is also buying nationwide low-band spectrum. Spectrum is a licensed portion of the radio-frequency range that carriers use to transmit signals.
Low-band signals can travel farther and pass through buildings better than higher-frequency signals.
However, they generally offer less capacity than higher bands. A network may use different spectrum bands and infrastructure to balance coverage with data capacity.
In short, the reported plan points toward a hybrid network. SpaceX could combine satellite coverage with terrestrial cell sites.
The company has not publicly detailed how it would divide those roles.
The scale and cost of a nationwide buildout
The 80,000-site target would be a major undertaking. The Wireless Infrastructure Association counted 158,500 purpose-built cellular towers operating in the U.S. at the end of 2025.
That makes SpaceX’s target roughly half that number. Still, “cell site” and “tower” are not identical terms. A site can use a tower, rooftop or other structure, while one tower can host equipment for multiple carriers.
Crown Castle operates about 40,000 U.S. cell towers, while American Tower has about 42,000 U.S. sites.
Private company Vertical Bridge owns roughly 18,000. Leasing space on existing infrastructure could help SpaceX expand faster than building every site itself.
Yet the company would still need network equipment, power, backhaul connections and permits.
TD Cowen estimated that a nationwide terrestrial network could cost more than $80 billion and require years of investment.
That estimate highlights the financial challenge. SpaceX’s recent spectrum purchase provides access to airwaves, while the reported tower talks address another essential need: connecting those airwaves to customers across the country.
Why mobile carriers reacted
The report raised the prospect of a new competitor for AT&T, Verizon and T-Mobile. Their shares fell after the news, while tower companies could benefit if SpaceX becomes a large new tenant.
Nevertheless, the reported talks remain early, and the cost and timetable are uncertain.
For now, the 80,000-site figure signals ambition rather than an operating network.
SpaceX would need to secure access, install equipment and build the systems that connect towers, satellites and customers.
Those steps will determine whether it can turn its spectrum and Starlink technology into a nationwide mobile service.
