SYSTEM AND METHOD FOR ASSET LOCATION IN WIRELESS NETWORKS

摘要

A system for tracking an asset includes wireless access points and a computing arrangement communicating with the access points to determine a location of the device as a function of first data, second data indicative of a travel time of a third signal from the device to three access points and the locations of the three access points. The first data includes one of first signal strength data and second signal strength data indicative of the strength of first and second signals transmitted, respectively, by the device and received by the three access points. The location area is an area within a predetermined reception range of the three access points. The arrangement determines the location of the device within the location area as a function of second data and a further location of each of the at least three further access points of the plurality of access points.
