Abstract
A system and method for determining a position of a first responder in a building, where the first responder is using a radio, and using a distributed antenna system. Each antenna has a level detector to detect and measure a strength of an input signal from the radio of the first responder to produce a level signal, a time tagger to tag the detected input signal with a timing signal, and a communication module to transmit the level signal and timing signal. A sensor processor connected with a signal distribution network is configured to receive the signal level and timing signal from the signal distribution network of each of the plurality of antennas, to determine the position of the radio relative to each of the plurality of antennas according to the level signal and timing signal.
