FES has been involved in E911 technologies and program management since 2005. We have worked with all major U.S. carriers, technology vendors, OEMs, and industry compliance organizations including CTIA, ATIS, APCO, and NENA. No single services vendor has as much exposure and experience in launching, testing, evaluating, and optimizing location-based systems as FES.

FES is currently executing the Indoor 911 Location Technologies Test Bed with participation of all major U.S. network operators, device OS manufacturers, and location technology providers. We are at the tip of next generation of E911 technologies that will provide far greater accuracy in locating 911 callers, including indoors.
