FCC Order
94-102 - Ensuring Wireless Compatibility with Enhanced 911 Emergency
Calling Systems Recognizing that American telephone habits were increasingly shifting to wireless communications, the FCC enacted Order 94-102 to ensure emergency personnel could obtain the correct location information for any wireless 911 call in order to respond in a timely and efficient manner. According to this order, wireless service providers are to introduce Enhanced 911 services to the wireless market in two phases. Phase I, to be implemented by April 1, 1998, calls for all wireless calls to be routed to the appropriate PSAP with the correct call-back number and cell site of origination. This information gives the PSAP a number to call back if the call is disconnected, and they can relay a general area of where the call came from. Phase II, to be provided by October 2001, calls for more detailed and accurate location information to be supplied to the PSAP from the wireless caller. Since wireless calls do not come from fixed addresses, this information is generally expressed in X/Y coordinates using the longitude and latitude of the phone's location when 911 was dialed. Wireless providers have a choice of technologies that can relay this type of information. To learn more about wireless ALI technology, click here.
