4. 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
