Pilot in Tennessee Finds Improved Location Data Results for 9-1-1 Calls
Tuesday, June 19, 2018 | Comments

Results from a project involving the use of Zetron’s MAX call-taking system’s handset location data capabilities for incoming calls to public-safety agencies are available. The location identification functionality is a product of Zetron’s partnership with RapidSOS, which sends life-saving data from connected devices to 9-1-1 and first responders.

The NG911 Clearinghouse from RapidSOS is integrated with Zetron’s MAX system to securely access device-based location information from enabled smartphones, without the need for an app.

The integration was used in a pilot project for the Tennessee Emergency Communications Board, in which the device-based location data captured was compared directly with automatic location information (ALI) location data and ground truth locations to measure accuracy. The results found 97 percent of call locations provided through the integration falling within 50 meters of ground truth, compared with only 44 percent of the provided carrier ALI data falling within the 50 meter range for the same calls.

“This is life-saving technology,” said Curtis Sutton, executive director of Tennessee’s Emergency Communications Board. “We can actually find somebody in seconds, rather than waiting until we can narrow that field down to the location that’s provided by the traditional methods. I haven’t seen a group of PSAPs (public-safety answering points) more excited about testing something than they have this technology because they realize the value of it.”

The RapidSoS data is made available within the Zetron interface in addition to traditional ALI data — not replacing it — and it provides more accurate location information, making it more useful and capable of saving time for dispatchers, first responders and the people in need of their help.
