Wireless computing devices are pervasive in many personal and business applications and include devices such as lap top computers, handheld Personal Digital Assistants (PDAs), cell phones, game controllers, bar code scanners, printers, etc. Various wireless communications channels include 802.11a,b,g and Bluetooth which are used to communicate data between the mobile device and a fixed base station. These wireless data channels may simplify usage of the mobile devices but pose a new problem of the device being lost or stolen. It is desireable for a means of physical security to detect when a wireless device has been moved beyond a predetermined boundry such as outside of a room or building.
