Abstract
A location information system (102) includes a controller (200), a location entry device (202), a memory device (204) and wireless communication units (206-209). The controller (200) receives location information from the location entry device (202), such as a keyboard or a global positioning satellite receiver, for storage in the memory device (204). The location information represents locations of predetermined areas (210-213), such as floors, rooms, hallways, stairways and elevators, associated with each of the wireless communication units (206-209) in a facility (110). A wireless communication unit (209) sends the location information to a wireless communication device (104), such as a cellular telephone device, over a short-range wireless communication channel (124), such as a radio frequency communication channel. Preferably, each of the wireless communication units (206-209) and the wireless communication device (104) include a short-range radio frequency transceiver designed to communicate over the short-range wireless communication channel (124) according to a Bluetooth technology specification. Preferably, the location information is used for E911 automatic location ident…
