AT&T will use phone location data to route 911 calls to the right responders [telecom]

It uses GPS and hybrid information to locate devices within 50 meters.

AT&T is launching location-based routing of wireless 911 calls to the appropriate call centers across the US, it announced. The company says it'll be the first US carrier to "quickly and more accurately identify where a wireless 911 call is coming from using device GPS and hybrid information." That'll allow it to route the call to the correct 911 call center (public safety answering point or PSAP) which can then "dispatch first responders to the right location faster," it wrote.

So far, wireless 911 call routing has been based on the location of cell towers, with accuracy often no better than 10 miles. The new system will be able to locate a device within 50 meters of its location, potentially reducing delays, particularly when a call is made at PSAP border areas where state, county or city boundaries overlap, AT&T said.
