System and method for wired network synchronization for real time location tracking

摘要

A system and method is provided for timing synchronization of receivers in a wireless network to improve the accuracy of real time location tracking methods utilize time difference of arrival methods. The synchronization signals are provided over the wired network which connects the wireless receiver base stations. The timing signals may be transmitted on an unused pair of wires, or may be superimposed on a pair of wires which are used for Ethernet data signals or a pair of wires used for Ethernet DC power signals.
