Method and system for personal area networks
First Claim
1. 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.

Abstract
A system (160) and method (400) is provided for validating a location of a tracking device. The method can include monitoring (902) a set of signal strengths (600) to one or more personal area networks (104) and one or more cellular towers (110), generating (906) a Radio Frequency Time Profile RFTP (700) from the set of signal strengths, comparing (908) the RFTP o coverage variation limits (720) of one or more pre-calibrated paths, and signaling (910) an alert if the set of signal strengths are not within the coverage variation limit of the one or more pre-calibrated paths. The RFTP is a time series of the signal strengths between the tracking device and the one or more PANs resulting from a change in location of the tracking device.
