AT&T Launching Location-Based Routing of 911 Calls Nationwide
May 10, 2022, 10:11 AM by Rich Brome @richbrome
AT&T is the first US carrier to launch location-based routing of 911 emergency calls to the appropriate call centers on a nationwide basis. Previously, 911 calls were routed to call centers based on the cell tower location, and then a more precise phone location transmitted to that call center. But one cell tower can cover an area with up to a ten mile radius, so in border areas where state, county or city boundaries overlap, 911 calls were sometimes routed to the wrong call center, causing delays in emergency response. With this new technology — called "Locate Before Route" from Intrado — a more precise phone location (within 50 meters) is used to decide which call center should receive the call, enabling a more efficient emergency response. AT&T has deployed the technology in 17 states and territories; the nationwide rollout is scheduled to be completed by the end of June.
