T-Mobile CTO John Saw: AI made 30,000 antenna adjustments in storm Fern

T-Mobile CTO John Saw: AI made 30,000 antenna adjustments in storm Fern

3 Key Points

  1. What happened

    T-Mobile CTO John Saw said the carrier is adding a layer of AI on top of its cell sites, hybrid generators and satellite backup, and used intent-based automation to make 30,000 real-time antenna adjustments during winter storm Fern in January.

  2. Why it matters

    Making that many adjustments in real time would not be possible with human engineers alone, so AI is being used to reduce the time it takes to restore coverage for first responders, hospitals and other essential services.

WHO IT HITSCIOs and network operations teams at hospitals, government agencies and financial institutions that depend on fast network restoration stand to gain from faster, more automated recovery. Remote hospitality and workforce operators, such as T-Mobile customer Aramark Destinations and Aramark Nexus, are early users of the managed hybrid SuperBroadband service.

Context & Analysis

T-Mobile's approach to network resiliency combines physical assets and software. In an emergency, the carrier deploys cell on wheels (COWs) and cell on light trucks (COLTs) to provide cellular backhaul and temporary coverage, according to CTO John Saw. Many of its cell sites now have hybrid generators for longer runtimes, and the company uses satellite connectivity as a backup.

AI sits on top of that hardware. Beyond the 30,000 antenna adjustments during winter storm Fern, T-Mobile used AI to ramp up capacity for gatherings such as the recent World Cup and to dial settings back once crowds disperse. Saw described this as anticipating customer intent and taking adaptive steps without engineers in the loop.

The limits are still being mapped. Omdia analyst Ildefonso De La Cruz Morales said AI can turn incoming data into real-time action and help avoid decision paralysis for first responders, but it remains early days for the sector, and where the AI compute runs is unresolved, which may shape how these tools are adopted.

FAQ
What is SuperBroadband?
It is a managed hybrid internet service T-Mobile launched earlier this year for businesses, combining fixed wireless 5G as the primary connection with satellite broadband from Starlink as a backup.
How does T-Mobile prioritize first responders?
It runs a dedicated network called T-Priority, a network slice supported by T-Mobile's 5G standalone core network that prioritizes connectivity for first responders.
Where is AI used for network resiliency?
T-Mobile recently added AI capabilities to automate antenna tilts and power-level changes and make network adjustments based on desired outcomes. Omdia's Ildefonso De La Cruz Morales said it is still early days and where the AI processing happens is not yet decided.
