NextNav has entered into an agreement with one of the nation’s largest wireless carriers, not yet named, to deliver vertical location for Enhanced 911 (E911), using NextNav’s Pinnacle 911.

Pinnacle 911 leverages the barometric sensors already available in phones, tablets and other devices to deliver “floor-level” altitude measurements that exceed the FCC mandate for 3-meter accuracy. The Pinnacle service compares device data to local conditions, subtracting the weather and other factors to leave behind a highly accurate altitude measurement.

NextNav altitude stations create a hyperlocal model of environmental conditions. The precisely surveyed, high-density network delivers “floor level” real-time altitude data nationwide.

NextNav’s dedicated, managed network makes Pinnacle available throughout metropolitan areas, providing comprehensive coverage that scales to meet a variety of use cases.

The delivery of vertical location to public safety answering points (PSAPs) nationwide will improve emergency response in the United States. It enables first responders to accurately locate wireless 911 callers in multi-story buildings, enhancing both safety and response times, and helping to save lives.

With NextNav’s Pinnacle 911 reaching more than 4,400 cities and towns in the United States, including 90% of buildings above three stories, implementation of the service will exceed the Federal Communication Commission’s (FCC) Z-axis requirement for nationwide E911.

“For over two decades, one of public safety’s key needs has been 3D geolocation information — especially floor-level vertical location,” said Ganesh Pattabiraman, CEO of NextNav. “Partnering with one of the nation’s largest wireless carriers to deliver precise, Z-axis information will not only improve geolocation information for PSAPs, but save lives by reducing emergency response times by more than 80%. This adoption of our Pinnacle technology for 911 marks a historic step forward for communities around the nation, and public safety as a whole.”

In an independent evaluation by the Cellular Telecommunications and Internet Association commissioned by the FCC, Pinnacle was able to deliver floor-level accuracy (defined as ±3 m) 94% of the time, consistently exceeding the 80% benchmark set by the FCC.

NextNav’s Pinnacle service enables applications and technologies that rely on precise altitude data across industries, including public safety, mobile apps and gaming, lone worker tracking as well as out-of-home retail experiences.

NextNav’s extensive list of existing partners and customers includes AT&T FirstNet, Intrepid Networks, 3am, TRX Systems, Qualcomm, Bosch, Unity and Unreal Engine.
