Application Example: E911 Cellular Location

What is E911?

Enhanced 911 or E911 is a technology mandated by the FCC that allows emergency services staff to locate the geographic location of a cellular caller making an emergency call to 911. The first phase of this mandate, established in 1998*, required the carrier to pinpoint the number of a wireless 911 caller and the location of the antenna (base station) that received the call. Phase Two requires wireless carriers to provide the geographic location within 50-300 meters of the cell phone itself (depending on the type of technology used). Phase Two is to be implemented by the end of 2005.
