Description: A letter report issued by the Government Accountability Office with an abstract that begins "Although states faced challenges and delays in the past, states have made significant progress implementing wireless Enhanced 911 (E911) since 2003. Wireless E911 deployment usually proceeds through two phases: Phase I provides general caller location information by identifying the cell tower or cell site that is receiving the wireless call; Phase II provides more precise caller-location information, usually within 50 to 300 meters. Currently, according to the National Emergency Number Association (NENA), nearly 98 percent of 911 call centers, known as Public Safety Answering Points (PSAPs), are capable of receiving Phase I location information, and 97 percent have implemented Phase II for at least one wireless carrier. This represents a significant improvement since 2003 when implementation of Phase I was 65 percent and Phase II was 18 percent. According to NENA's current data, 142 U.S. counties (representing roughly 3 percent of the U.S. population) do not have some level of wireless E911 service. The areas that lack wireless E911 are primarily rural and tribal areas that face special implementation challenges, according to federal and association officials."
