The Problem 85% of 911 calls are made by cell phone Unlike landlines, cell phones cannot be easily pinpointed The FCC and APCO have been attempting to adopt and implement standards for spatial accuracy Within 50m indoors 50% of calls in the first 2 years of implementation 80% within 5 years Tucson does not have a set of spatial standards for locating 911
