    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.

    Abstract: The disclosure is directed to determining a location of a user equipment (UE) in a poor positioning environment based on locations of one or more devices. A first location and a first location uncertainty of the first device is received from a first device, a determination whether or not the first location uncertainty is less than a location uncertainty of the UE is made, and if the first location uncertainty is less than the location uncertainty of the UE, the location of the UE is determined based on the location of the first device and a distance to the first device.

    Abstract: Systems, apparatus and methods for communicating and using a geofence while maintaining privacy are presented. A geofence is based on at least one RF fingerprint. The RF fingerprints include absolute information that is transformed into a one-way matrix (A) by application of a one-way function. The absolute information may identify a transmitter (e.g., by location, address or the like). An equation 0=Ax (where 0 is a zero vector, A is the one-way matrix and x is a signature vector) is solved to reveal one possible solution for the signature vector (x). This signature vector (x) is communicated rather than the RF fingerprints themselves, thus obscuring the absolute information and maintaining privacy.

    Abstract: Systems, apparatus and methods in a mobile device for creating and/or using a geofence are presented. When creating a geofence, a mobile device collects at least one RF fingerprint. Each RF fingerprint includes transmitter information from a plurality of transmitters. The transmitter information includes information identifying the transmitter (e.g., location or MAC address of the transmitter) referred to here as absolute information. The transmitter information may also include information indication a relative position of the mobile device with respect to the transmitter (e.g., RTT or RSSI) referred to here as relative information. The RF fingerprints are used to define a geofence. Granularity may further be used to define a geofence. A first mobile device creates the geofence and sends it to a second mobile device, which looks for the geofence. When using the geofence, a second mobile device may trigger an application when a breach of the geofence is detected.
