Abstract: A system and method of wireless device location mapping comprising measuring a signal strength of a wireless signal generated by the wireless device at a plurality of sensor devices positioned at a plurality of sensor locations; determining a range from each of the plurality of sensor devices to the wireless device based on the measured signal strength; and generating a plurality of ranging spheres, a respective one of the plurality of ranging spheres corresponding a respective one of the plurality of sensor devices and being centered at a respective one of the plurality of sensor locations and having a radius that is proportional to the determined range of the respective one of the plurality of sensor devices to the wireless device.

Abstract: A method of wireless device location determination includes defining a region of interest comprising a plurality of sensors. A reference frame and a grid comprises a plurality of simulation points with locations based on a coordinate system associated with the region of interest. Location coordinates for the plurality of sensors are established. A plurality of simulated wireless signal strengths is determined for each simulation point. A plurality of simulated signal strength matrix is generated using the plurality of simulated wireless signal strengths. A composite matrix is generated based on the plurality of simulated signal strength matrices. Wireless signal strength is measured at each of the plurality of sensors based. A measured wireless signal strength vector is then generated based on the measured wireless signal strength. A location of the intrusive device is then determined based on the measured wireless signal strength vector and the composite matrix.
