Patent ID: 10015627

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. The system and method further comprises generating a new radius for each of the plurality of ranging spheres by expanding the radius for each of the plurality of ranging spheres by a small increment while maintaining a ratio between any two of the radii of the plurality of ranging spheres, determining a number of intersection points and adding a location of each of the intersection points to a map.
