This document is an ESIF Technical Report. The FCC has established accuracy requirements for network and handset based location solutions for Enhanced 9-1-1 emergency call services (found in the Commission¿s Third Report and Order, adopted September 15, 1999). As a result, ESIF identified the need for industry-accepted requirements for testing the accuracy performance of Wireless E-9-1-1 Phase II systems. This document provides a common frame of reference that individual stakeholders can use to validate the accuracy methodology of 9-1-1 location technologies.
