T-Mobile US stock marks AI-RAN milestone with Nokia and Nvidia

T-Mobile, Nokia and Nvidia completed what the companies described as the world's first AI-RAN voice call on a live commercial network, according to Light Reading. The milestone was reported on Wednesday, October 21, 2026, and took place at a T-Mobile site near the carrier's headquarters in Bellevue, Washington.

From Lab Test To Live Network

The call used Nokia's Massive MIMO radio, Nokia's 5G anyRAN software and server infrastructure built on Nvidia's Aerial RAN Computer platform. The site connected to T-Mobile's live production network, a commercial 5G core and commercial user equipment. That setup moves the technology beyond a controlled laboratory environment, although the companies did not publish operating figures for the call itself.

Nokia said the next phase of field trials will explore additional spectrum bands and the ability to run AI inferencing workloads alongside radio access network functions. For T-Mobile, the practical objective is to test whether accelerated computing can support network operations and future AI applications on shared infrastructure. The announcement does not yet establish the financial return or deployment scale of the technology.

Ericsson Trial Adds Operating Evidence

Light Reading also reported a separate T-Mobile trial with Ericsson in New York City. AI-managed beamforming delivered a 16% improvement in downlink throughput, 12% higher spectral efficiency and a 10% increase in downlink data volume during peak usage hours. The trial also produced a 50% increase in advanced beamforming using full-band sounding reference signals.

The Ericsson results give investors a second angle on T-Mobile's network strategy. The carrier is testing a GPU-based platform with Nokia and Nvidia while also using Ericsson's own radio compute and silicon approach. Light Reading said an earlier T-Mobile trial with an AI-native scheduler and link adaptation produced 10% higher spectral efficiency and a 15% increase in downlink throughput. These figures relate to separate trials and should not be combined into a single network-wide gain.

Technology Milestone, Commercial Test Ahead

The AI-RAN developments could support higher capacity in congested areas if the gains hold across more sites, spectrum bands and traffic conditions. The immediate investor question is whether the trials can translate into reliable performance improvements without raising network costs or complicating the carrier's deployment model. Customer-facing changes are not part of the announcement.
