Wireless Phase II coverage is available to cell phone users in areas where wireless carriers and local 911 centers have invested in technology enhancements to protect wireless callers in emergencies. Where Phase II coverage is available, the 911 dispatcher will see the wireless telephone’s call back number and the location of the caller by latitude and longitude within a few hundred feet. This enhanced location technology is mandated by the Federal Communications Commission, and wireless companies are working to implement Phase II coverage gradually.
