Abstract: A cellular phone type network tracks public safety workers and their vehicles for computer aided dispatching and automatic vehicle and personnel locating. A worker carried repeater unit communicates by radio with nearby cells, sending periodic identifying signals. The network locates the unit position by methods used for 911 caller locating. A vehicle mounted mobile data terminal with input and display is in short range wireless communication with the repeater unit to communicate therethrough with the network. A panic button on the repeater unit initiates rapid emergency signals to the network to both call for help and locate the worker/vehicle.
