Abstract: A method and apparatus for tracking the location of assets and persons are provided. According to the invention, position information is provided to a central monitoring station aperiodically. The central monitoring station utilizes software agents to analyze the information received from remote tags, and to determine the appropriate action to take with respect to that information. In particular, the central monitoring station provides aperiodic notifications to authorized users regarding the position and status of a monitored person or asset. The central monitoring station operates without requiring human analysis of the information received from remote tags. Furthermore, the use of aperiodic transmissions of information to the central monitoring station, and the use of software agents in the central monitoring station, allows the present invention to efficiently process information received from a large number of remote units.
