Patent ID: 8023959

Claim:
A tracking system for validating a location suitable for use with location Positioning Systems, comprising: a tracking device that generates a Radio Frequency Profile (RFTP); one or more personal area network units (PANs) communicatively coupled to the tracking device; and a processor operable to: receive GPS data reporting an immediate location of the tracking device; project a path of the tracking device based on a history of the RFTP; predict a location of the tracking device along the path; determine whether the location is within a region of a last received GPS reading; raise an alert if the location is outside a coverage variation limit of a pre-calibrated path; and wherein the RFTP is a signature of communication patterns recorded between the tracking device, the PAN, and, if present, one or more external communications systems, and the tracking system validates a location of the tracking device based on the RFTP.
