Abstract
An asset tracking system includes a station, transmitting points, and tag units. The tag units can be used for communicating with the transmitting points. The station receives data associated with signal strengths between wireless access points and tag units. The station analyzes the data associated with a number of the transmitting points and determines the location of the tag units.
