Abstract
A method and system for verifying a location value reported by an electronic device. The reported location value and spectrum sensing data containing signal strength measurements for each channel of plural channels are received from the electronic device. A predicted RF footprint for the reported location is generated. The predicted RF footprint includes signal strength values for each of the plural channels. Each signal strength value is representative of RF energy that the electronic device ought to detect if the electronic device is actually present in the reported location and each signal strength value is determined as a function of known characteristics of radio devices with known locations. A determination is made as to whether the received signal strength measurements and the predicted RF footprint sufficiently correlate to validate that the electronic device made the signal strength measurements at the reported location.
