"This document focuses on providing a set of minimum requirements for the ""Accuracy Testing"" phase of a typical network deployment of positioning technologies for Wireless E-911. Other testing phases are beyond the scope of this document. This document addresses the technical aspects of accuracy testing. Testing and carrier compliance reporting are two distinct and separate issues. The application of this methodology to compliance reporting is beyond the scope of this document. INTRODUCTION The United States Federal Communications Commission has established accuracy requirements for network and handset based location solutions for Enhanced 9-1-14 emergency call services. These requirements can be found in the Commission's Third Report and Order@ adopted September 15@ 1999. The Emergency Services Interconnection Forum (ESIF) identified the need for industry accepted requirements for testing the accuracy performance of Wireless E-911 Phase II systems. This document neither recommends@ nor imposes a specific test methodology@ but rather provides a common frame of reference that individual stakeholders can use to validate the accuracy methodology of 911 location technologies. This document provides a set of minimum requirements individual test methodologies should comply to. Every possible effort has been made to ensure that these requirements remain technology neutral. Per current ESIF Operating Guidelines@ due process has been followed in the creation of this document@ and development has been open for participation within the bounds of ESIF."
