Abstract
A wireless communication system () employs a method () and apparatus for automatically tracking locations of wireless communication devices () in a geographic area, such as an ad hoc area of an emergency scene, that is divided into two or more zones (). A wireless communication device () or a host device (), determines a location of the wireless device (). The wireless device's location is then associated with one of the zones (). An indication () of a zone change is presented to a user of the wireless device and/or the host device (), as applicable, in the event that the wireless device's location reflects a transition of the device from one zone to another. Alternatively, each wireless device () might be associated with a corresponding group, such as a fire department, and the zone change indication might include an identifier () of the wireless device's group.
