Location Accuracy for Emergency 911 Cell Calls
While the Federal Communications Commission (FCC) moves to improve location accuracy for Emergency 911 cell calls, limitations in both triangulation and GPS location methods will still result in location inaccuracies. Locations can be determined by triangulating arrival times, what the FCC refers to as a network-based solution or via GPS identification, or handset-based solution according to the FCC. Because both can be affected by line of sight (LOS) wave propagation, densely forested areas or remote locations can cause location inaccuracies of up to ten miles while still being FCC compliant. Performing regular Public Service Answering Points (PSAPs) will help emergency responders better understand vulnerable areas and adapt to these circumstances for faster response times.
