Patent abstract
A method for inferring location of a mobile device is provided. A radio frequency fingerprint is taken for a mobile device, wherein the radio frequency fingerprint includes cell tower data and cell sector data that includes a cell sector through which the mobile device is not communicating. Whether the radio frequency fingerprint matches a previous radio frequency fingerprint associated with a location fix is determined. A location fix technology is executed for the mobile device in response to a determination that the radio frequency fingerprint does not match the previous radio frequency fingerprint.
