The location of unmodified wireless assets in a wireless communication network may be identified using time differences of arrivals of a communication sequence at different network receivers. Time-stamping devices may include correlator circuits in parallel with signal decoders to time-stamp communication sequences. Cellular wireless networks may be frequency-multiplexed to increase spatial time-stamping density. Tags may be attached to passive assets to provide location identification information to network devices. Locations of assets broadcasting standard 802.11 radio frequency structures may be identified. Noise inherent in correlating a communication sequence may be reduced by using a selected correlation function.
A method for identifying a location of an asset in a communication network, said network having at least a first receiver device and a second receiver device, each receiver device having a known position, said method comprising:
The method of claim 8 wherein said identifying comprises estimating an intersection of said first plurality and said second plurality.
A method for identifying a location of an asset in a communication network, said network having a first receiver device at a first station and a second receiver device at a second station, each receiver device having a known position, said method comprising:
A method for identifying a location of an asset in a communication network, said network having at least three receivers, said method comprising:
