A TDOA (time difference of arrival) location system, in which mobile wireless devices broadcast wireless signals which are received by two or more transceivers deployed in the vicinity of the mobile wireless device. Each transceiver measures the TOA (time of arrival) of the received broadcasted signal and reports the TOA to a central server. The central server then calculates the mobile device position using multi-lateration of TDOA values. The system uses fiber optic links between the antennas and the transceivers deployed in the location area to provide unique advantages that couldn't be achieved using RF coaxial cables.
