Wireless E9-1-1 Project Description
In accordance with Federal Communications Commission (FCC) Order 94-102, the California 9-1-1 Emergency Communications Office (State 9-1-1 Office) has launched a project to implement enhanced 9-1-1 services (Wireless E9-1-1) for wireless telephone users throughout California. Project objectives include preparing all California public safety answer points (PSAPs) to accommodate the information to be delivered by wireless carriers under Phase I and Phase II of the Order. Phase I specifies that the telephone number and receiving cell site or sector of the 9-1-1 caller be delivered to the PSAP. Phase II adds a more precise location, (usually with 50-100 meter accuracy or better) in the form of latitude/longitude coordinates, to the Phase I information.
A major emphasis of the wireless project is the redistribution of statewide wireless 9-1-1 call volumes to local PSAPs. Currently a limited number of California Highway Patrol (CHP) communication centers handle the overwhelming majority of wireless 9-1-1 calls. To accommodate these routing changes, new legislation was passed in 2000 (Assembly Bill 1263) and signed into law, effective January 1, 2001. This will allow approximately 500 local PSAPs to assist the 24 CHP communication centers in handling the estimated 8 million wireless 9-1-1 calls made in California each year.
