## Abstract

In this document, the Commission continues to strengthen its existing Enhanced 911 (E911) location accuracy regime for wireless carriers by retaining the existing handset-based and network-based location accuracy standards and the eight-year implementation period established in our September 2010 E911 Location Accuracy Second Report and Order but providing for phasing out the network-based standard over time. We also require all Commercial Mobile Radio Service (CMRS) providers, launching new stand-alone networks, to comply with the handset-based location criteria, regardless of the location technology they actually use. In addition, we will require wireless carriers to periodically test their outdoor E911 location accuracy results and to share the results with Public Safety Answering Points (PSAPs), state 911 offices, and the Commission, subject to confidentiality safeguards.
