Starlink Mobile in talks over 80,000 cell sites, FCC approves Tristar spectrum with ground-network waiver…

SpaceX is putting together the full set of pieces for Starlink Mobile to become the fourth-largest national carrier. The pieces are satellites (15,000 direct-to-cell satellites), spectrum (S-band for the main traffic, 800MHz for indoor coverage, and a newly acquired 15MHz of AWS-3 uplink with no obligation to build a ground network) and ground towers (talks

over at least 80,000 US cell sites, roughly half of the nation's 158,500 dedicated towers, with Crown Castle, American Tower and Vertical Bridge all in talks). The price is another layer of capex and long-term leases. On 21 Oct the FCC approved the purchase of Tristar's AWS-3 uplink spectrum and waived the ground-site requirement so that satellites can use it. The signal matters more than the volume. On the same day T-Mobile opposed another commission proposal to open more spectrum to satellites, citing interference with 5G, so regulatory pushback from the traditional carriers is escalating. Falcon 9 is being phased out to make way for Starship, and the Space Force is reshuffling its launch schedule (Politico, 22 Oct, paywalled). In the short term, the pace of delivery on the 18 national security launch contracts is at risk, which leaves a window for ULA and Blue Origin. On the Starshield speed limit in Ukraine, Trump phoned Musk on 21 Oct to demand that it be lifted and told reporters it had been restored. The Kyiv Independent says that is all untrue and that the 161 km/h limit remains. Members of Congress from both parties have jointly demanded that Ukraine's access be guaranteed. The issue has moved from 'who gave the order' to 'the switch is in Musk's personal hands'. Europe is speeding up its search for alternatives but has few ready-made options, which in the long run raises the political priority of IRIS² and Bromo. Reliance on the government is deepening: as of 1 Oct, federal contracts this year total at least $6.78 billion (close to twice the whole of 2024). Over the same period Musk has put about $366 million into the 2026 midterm elections, as the largest individual donor. If the Democrats flip the House, contracts, spectrum and launch licences could face congressional subpoenas and investigations.

Key evidence

Bloomberg, 22 Oct: SpaceX wants to secure at least 80,000 cell sites in the US and is in talks with tower companies including Crown Castle, with the lease value potentially running to several billion dollars. Crown Castle's CEO said on a call on 21 Oct that one can assume the company is talking to all parties, without naming names.
For scale (Wireless Infrastructure Association): the US has about 158,500 dedicated towers, so 80,000 is roughly half. Crown Castle has about 40,000, American Tower about 42,000 and Vertical Bridge about 18,000.
The full Starlink Mobile jigsaw: 15,000 direct-to-cell satellites, S-band for the main traffic, 800MHz for indoor coverage, and towers and home antennas as a ground supplement, which together make the fourth-largest national carrier.
On 21 Oct the FCC approved SpaceX's purchase of 3 unused AWS-3 uplink licences from Tristar (1695-1710MHz, 15MHz in total), covering 62 counties in 8 states and about 4% of the US population. The licences did not go to auction, and the ground-site requirement is waived so that satellites can use them.
T-Mobile publicly opposed another FCC proposal to open more spectrum to satellites on 21 Oct, arguing that it would interfere with its 5G network (PCMag, 22 Oct).
Politico, 22 Oct (paywalled, details not fully verified): SpaceX is phasing out Falcon 9 to make way for Starship. Many military satellites were not designed for Starship's interfaces and fairings, and the Space Force is reshuffling its launch schedule.

Starship must first obtain national security launch certification. In the short term the pace of delivery on the 18 national security launch contracts is at risk, leaving a window for ULA and Blue Origin.
Wall Street Journal, 22 Oct: Trump phoned Musk on 21 Oct to demand that the Starshield restrictions on Ukraine be lifted. Trump told reporters it had been restored, but did not confirm whether this came through the call.
Kyiv Independent: Ukrainian officials say it is all untrue and the 161 km/h limit remains in place. House members from both parties have jointly called for Ukraine's stable access to be guaranteed.
CNBC, 22 Oct: Europe and Ukraine are speeding up their search for alternatives, but there are few ready-made options. Over the long term this raises the political priority of IRIS² and Bromo.
CNBC/FedScout: as of 1 Oct, SpaceX's federal contracts this year total at least $6.78 billion, close to twice the full-year 2024 figure.
Musk has put about $366 million into the 2026 midterm elections and is the largest individual donor. The Democrats are expected to take the House, and if control flips, SpaceX's contracts, spectrum and launch licences could face congressional subpoenas and investigations.

Catalysts to watch

Pace of signing for the 80,000-site lease deal (follow-up earnings reports or press releases from Crown Castle, American Tower and Vertical Bridge)
Outcome of the FCC's follow-up proposal to open more spectrum to satellites (the result of T-Mobile's opposition)
Progress of Starship's national security launch certification
Effect of Starship replacing Falcon 9 on the delivery pace of the 18 national security launch contracts
Result of the US midterm elections in Nov 2026 (a Democratic win of the House would add to SpaceX's political exposure)

Progress of sovereign constellations such as Europe's IRIS² and Indonesia's Bromo (spurred by the Starlink episode in Ukraine)
Timetable for the commercial launch of Starlink Mobile

Risks

Building a ground network for Starlink Mobile adds to already heavy capex, and long-term tower leases add another layer
As Starlink Mobile turns carriers such as T-Mobile from partners into competitors, their regulatory pushback is escalating
A delay in Starship certification would disrupt the pace of the 18 national security launch contracts in the short term, leaving a window for ULA and Blue Origin
The Ukraine speed-limit episode has cemented the narrative that 'the switch is in Musk's personal hands'. Over time this raises the political priority of European sovereign constellations and erodes Starlink's share with international governments and militaries
If the Democrats win the House, SpaceX's contracts, spectrum and launch licences face congressional subpoenas and investigations

The government's share of business is rising just as political exposure grows (Musk's $366 million of personal political spending). Government business is the most certain source of growth but also the most politicised
The Tristar spectrum from the FCC is small (15MHz, 4% of the population), so its contribution to actual network capacity is limited
Politico's report on the Space Force reshuffling launches is paywalled, and details are not fully verified
