Abstract
Systems, apparatus and methods in a mobile device for determining a breach of a geofence is presented. A reference radio frequency (RF) fingerprint is obtained by the mobile device, the reference RF fingerprint defining the geofence. The reference RF fingerprint may be generated by the mobile device or received from a different mobile device. The mobile device scans for RF signals and determines a scanned RF fingerprint based on the scan for RF signals. A breach of the geofence is determined using the reference RF fingerprinting and the scanned RF fingerprint.
