Noncooperative 802.11 MAC Layer Fingerprinting and Tracking of Mobile Devices

Figure 1

An example of a noncooperative position tracking topology. Several low to medium range Wi-Fi MSs with known positions are connected to a central server via a Local Area Network (LAN) or the Internet. The system can track a roaming target by intercepting signals transmitted by the device and mapping the detection to the location of the corresponding MS.
