1. A system for tracking persons and other assets in a structure, comprising:
- a mobile unit for transmitting a RF beacon signal, said signal being distinctive of the specific mobile unit;
a network of RF transceivers of known location forming a wireless array for receiving said RF beacon signal when said signal is within a predetermined distance of one or more of said network of RF transceivers, said one or more of said network of RF transceivers also transmitting said received RF beacon signal and a signal representative of itself to other of said network of RF transceivers proximate its location to deliver said received RF beacon signal through said array; and
a computer gateway for receiving said transmitted signals from said network and having a display, said computer being adapted to determine the location of said mobile unit from said transmitted signals and display said location on said display.

Abstract
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. The computer determines the location of the mobile unit from the transmitted signals and displays the location.
