In-building tracking system for distributed antenna systems

A system for determining a position of a first responder in a building, where the first responder is associated with a radio, the system comprising:

• a plurality of antennas placed within the building, each of the plurality of antennas configured to detect an input signal from the radio of the first responder, a time tagger to tag the detected input signal with a timing signal, and a communication module to transmit a representation of the detected input signal and the timing signal;
• a signal distribution network comprising a physical mesh network configured to communicate, via a communication network, the representation of the detected input signal and the timing signal associated with each of the plurality of antennas from the communication module;
• and
• a sensor processor connected with the physical mesh network and configured to receive a signal level and timing signal from the signal distribution network of each of the plurality of antennas, and to time-align detected input signals by each of the plurality of antennas, wherein two or more of the time-aligned plurality of antennas are used to determine the position of the radio of the first responder relative to each of the two or more of the plurality of antennas according to the level signal of each detected input signal.
