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.
