ATIS 0500039

This Technical Report summarizes the research and findings associated with ESIF Issue 99. It explores specific characteristics of sub-optimally routed wireless emergency calls, such as where they occurred as well as the distribution of their distances from the boundaries of the Public Safety Answering Points (PSAPs) to which they routed. This report also includes recommendations derived from these findings for cell sector based routing and Location Based Routing (LBR) implementations.
