'This is a wow moment': T-Mobile has made the world's first AI-RAN call, and it could mean huge changes for the next generation of staying in touch

• T-Mobile, Nokia, and Nvidia claim the first AI-RAN call through a commercial cell site in Bellevue, Washington
• The call ran Nokia's radio software on Nvidia GPUs, but no AI performance data was provided
• Commercial AI-RAN gear is due in 2027, with 6G networks expected around 2030

T-Mobile, Nokia, and Nvidia say they have completed the world's first AI-RAN (Artificial Intelligence - Radio Access Network) call, routed through a commercial cell site in Bellevue, Washington.

The call ran over T-Mobile's live production network using a Nokia Massive MIMO radio, Nokia's 5G anyRAN software and servers built on Nvidia's Aerial RAN Computer (ARC) platform.

This wasn't a lab rig with test handsets, either, but a real-world setup that held; according to Nvidia's announcement, the site connected to T-Mobile's existing 5G Standalone core and a commercial smartphone.
