Concerns California's enhanced program for wireless 911 calls (wireless E911), which would communicate to emergency response dispatchers the locations & callback numbers of callers from mobile phones. California has addressed many of the concerns raised by two Federal reports on the nationwide implementation of wireless E911. The implementation is a cooperative effort among various key players, including the Calif. Highway Patrol, which currently answers most wireless 911 calls in the State; local answering points, some of which are opting to accept wireless E911 calls in their areas; & private wireless carriers & local exchange carriers. Wireless E911 should be implemented in most of the State by Dec. 2005.
