T-Mobile Says It Will Be First With 6G in the US, and the Carrier Is Betting on Physical AI to Justify the Upgrade

T-Mobile claimed on its third-quarter earnings call this week that it will be the first carrier to launch 6G in the United States, with chief technology officer John Saw pointing to integrated sensing and communications as the defining capability. Saw said 6G will be “the first G where the basestations and radios behave as radars,” opening use cases in remote sensing that he expects will drive significant traffic growth. The carrier did not commit to a launch date but referenced the industry expectation of a 2030 timeframe for 6G networks.

The physical AI angle is what distinguishes T-Mobile’s pitch. Saw published a blog ahead of the earnings call describing work with Figure AI’s humanoid robots, Serve Robotics’ delivery robots and 5G-connected cameras in San Jose. T-Mobile has teamed with Amazon Web Services to build what it calls a “kinetic edge,” combining its 5G-Advanced network and distributed edge compute with AWS cloud orchestration and AI services. The carrier expects to monetise this through a cut of device cost savings as compute moves from endpoints to the network edge.

Traffic assumptions are shifting too. Saw said his 2030 mobile traffic model is “still downlink heavy but increasingly uplink rich,” driven by AI wearables, AI agents and what he described as “explosive growth by then of physical AI devices, like humanoids, robots, delivery drones, vehicles and factory machines.” The upcoming spectrum auctions for upper C-band and 2.7 GHz offer T-Mobile capacity for 6G as well as uplink bandwidth expansion.

The financial backdrop is strong. T-Mobile reported third-quarter service revenue of $19.4 billion, up 6 percent year-on-year, and adjusted EBITDA of $9.6 billion, up 11 percent. Net income rose 27 percent to $3.5 billion. Postpaid service revenue grew 9 percent to $16.3 billion. The carrier raised full-year guidance and reported 274,000 postpaid net additions in the quarter, on track to pass one million for the year. T-Mobile now serves 127 million postpaid customers, up from 121 million a year earlier.

T-Mobile’s spectrum spending is set to rise. The carrier expects to allocate more capital to spectrum ahead of FCC auctions in 2027 and 2028, weighing spectrum costs against network densification. The company also ruled out an MVNO deal with SpaceX’s Starlink for consumer services, while leaving open the possibility of commercial edge compute partnerships.

The broader industry context comes from 3GPP. Release 21 work is narrowing toward a 5G-based evolution for 6G, with 1024-QAM uplink modulation advancing for fixed wireless access. Verizon’s chief technology officer Yago Tenorio has argued that 6G needs an architectural rethink to handle AI-driven uplink demand and avoid repeating 5G’s standardisation mistakes. Ericsson’s Narvinger has defended custom silicon for AI RAN, citing 10 percent spectrum-efficiency gains. The vendor and operator community is still debating what 6G should prioritise.

T-Mobile’s 6G timeline signals that current-generation 5G-Advanced base stations will remain the installed base through at least 2028. The physical AI opportunity is a software and edge compute story, not a radio hardware replacement cycle.

Supplier’s note: We hold 5G-Advanced base station and baseband units from the 2025 production batch in Shenzhen stock, roughly 45 units across six SKUs, with lead time of five to seven working days on fresh orders. Cross-reference stock includes compatible power amplifiers, filters and mounting brackets from third-party vendors that fit the same tower configuration. Customers typically order in lots of two to four units for site upgrades, and we see repeat orders from the same system integrators every five to seven weeks. Pricing holds for 30 days from quotation. We also stock spare fans, power supplies and cable assemblies for the same chassis families, and can arrange on-site installation support through our partner network in North America and the Middle East region.
