Abstract: A method and system for the detection, notification and tracking of cargo theft proposes to install, inside cargo to be protected, a tracking device having communication and dead reckoning capabilities. As long as the tracking device senses that it is within a virtual fence generated by an access point, it lays dormant. When the tracking device senses that it is no longer within the virtual fence it activates the dead reckoning capabilities and communicates with a central server to supply dead reckoning data thereto. The central server processes this data and determines the current location of the cargo.

Abstract: A device, system and method for the detection of intrusion using radio frequency (RF) signals are provided. The system comprises at least two devices. The system detects intrusion by measuring the Received Signal Strength (RSS) of a RF signal sent by the first device to the second device via a RF channel. The RF signal receiving device determines if the variation of the current RSS value is due to an intrusion in the RF channel or not an acts appropriately.
