A device and method for determining and automatically transmitting a geographic location of a wireless alarm device during a potential emergency utilizing enhanced wireless communication and position location systems. In one aspect, a wireless alarm device includes a smoke alarm interfaced with a wireless transceiver, configured to operate over a plurality of existing wireless telecommunications and position location networks. The wireless transceiver can be a cellular processor comprising multiple radio frequency bands and air interface standards with an integrated memory for storing emergency identification information. Another aspect includes an integrated assisted global positioning receiver and broadcast television receiver, configured to operate with global positioning systems and broadcast television positioning systems. In one mode of operation, upon sensing the presence of smoke, the wireless transceiver automatically transmits stored emergency identification information signals and a geographic location of the wireless alarm device to a dispatch center.
