Strong networks and public safety

A strong network can support the public services that help us feel safe at home and in our communities.
Improved information sharing, location accuracy, and connectivity help make communities safer, supporting:
  • 911 service, emergency and
    first responders
  • AMBER and Silver alerts
  • Natural and man-made disaster alerts
  • Communication apps during and after
  • Reverse 911 alerts

Mobile connectivity and Enhanced 911 service

Mobile connectivity can serve as a lifeline between first responders and people in distress in the event of an emergency, a natural or man-made disaster, or a threat to the community. Enhanced 911 systems (E911) provide dispatchers with the location data they need to find wireless callers who need help.

Wireless subscribers also receive Reverse 911 and Emergency Alerts—text or voice messages sent to subscribers in a specific area affected by a local or regional emergency.

Enhanced 911 location accuracy

The Federal Communications Commission (FCC) requires wireless providers to relay location data to dispatchers on live 911 calls. The accuracy of that data varies; determined by signal strength, mobile device model, and whether GPS is enabled.

As we strengthen T-Mobile networks across the US, we are actively improving location accuracy for everyone.

Horizontal accuracy

In 2015, the FCC defined milestones for horizontal accuracy improvement – requiring horizontal location accuracy to be within 50m (162 ft) for 80% of mobile 911 calls by April 2021. T-Mobile met, and exceeded this milestone well ahead of the schedule.

Vertical accuracy

When an emergency call is placed in a high-rise building, dispatchers need to know which floor to send responders to. We are continually working with the FCC and developing the technology to meet the most up-to-date requirements.

Personal and public safety beyond 911

In emergencies, wireless connectivity can sometimes be a matter of life or death.
