A system for tracking persons in a structure, using a mobile unit for transmitting a distinctive beacon signal to a wireless array network of RF transceivers when the signal is within a predetermined distance of one or more RF transceivers, and transmitting the received RF beacon signal and a signal representative of itself to other RF transceivers through the array to a computer gateway.
