摘要:
Described is a system and method for tracking an asset. The system may include a plurality of wireless access points and a computing arrangement communicating with the access points. The arrangement determines a location area of the device as a function of first data and a location of each of at least three access points of the plurality of the access points. The first data includes at least one of first signal strength data and second signal strength data. The first signal strength data is indicative of a strength of a first signal transmitted by the device and received by the at least three access points. The second signal strength data is indicative of a strength of a second signal transmitted by the at least three access points and received by the device. The location area is an area within a predetermined reception range of the at least three local 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. The second data is indicative of a travel time of a third signal from the device to each of the at least three further access points.
