Under the new system, iPhones will send their exact location to a RapidSOS dispatcher, which will then forward the coordinates to local emergency response centers. That should make it easier for ambulances and paramedics to reach callers and shave precious minutes off response times, potentially saving 10,000 lives per year, according to federal regulator estimates.
The new feature will be packaged as part of iOS 12, an iPhone software update due later this year.
The existing 911 system was designed for a time when everyone used landlines and call operators could easily pinpoint phones’ locations. Now, though, more than 80% of 911 calls are made on cell phones in many parts of the country, according to the National Emergency Number Association. Cellphone carriers currently share location estimates with emergency dispatchers, but these can be off by as much as a few hundred yards.
