摘要

A method and apparatus for locationing an object in a communication network. The method includes transmitting by a wireless transceiver fixed to the object of unknown location a plurality of radio frequency (RF) packets to a plurality of locationing receivers (LRs) in the communication network. The method further includes determining by each locationing receiver the local time of arrival of the RF packet and places a time stamp on the received RF packet based on a corresponding local clock, wherein the local clocks of the locationing receivers are synchronized based on a plurality of RF beacon packets transmitted by at least one reference transmitter at a known location.
