Abstract
Systems and methods for determining a location of a device with a wireless network. Characteristics of signals received from the device at a plurality of nodes are measured. Based upon the measurements, estimates of the range from the device to the nodes are made. Then, based upon the estimated ranges, and knowing the location of the nodes, a location of the device is determined.
