NextNav’s enhanced 911 technology locates people within buildings—but may interfere with millions of existing devices.

Cell phones replacing landlines are making it difficult to accurately locate people who call 911 from inside buildings. If a person having a heart attack on the 30th floor of a giant building can call for help but is unable to speak their location, actually finding that person from cell phone and GPS location data is a challenge for emergency responders.

Thus, new technologies are being built to accurately locate people inside buildings. But a system that is perhaps the leading candidate for enhanced 911 geolocation is also controversial because it uses the same wireless frequencies as wireless Internet Service Providers, smart meters, toll readers like EZ-Pass, baby monitors, and various other devices.

NextNav, the company that makes the technology, is seeking permission from the Federal Communications Commission to start commercial operations. More than a dozen businesses and industry groups oppose NextNav (which holds FCC licenses through a subsidiary called Progeny), saying the 911 technology will wipe out devices and services used by millions of Americans.
