A wireless communication unit ( ) sends the location information to a wireless communication device ( ), such as a cellular telephone device, over a short-range wireless communication channel ( ), such as a radio frequency communication channel. Preferably, each of the wireless communication units ( ) and the wireless communication device ( ) include a short-range radio frequency transceiver designed to communicate over the short-range wireless communication channel ( ) according to a Bluetooth technology specification. Preferably, the location information is used for E911 automatic location identification in the facility ( ). The location information may be solicited or unsolicited from the location information system by the wireless communication device ( ). When the location information is solicited, the location information is either pulled by the wireless communication device ( ) or pushed by the location information system using a location information service.
