A method includes obtaining signal information based on wireless signals communicated between an electronic device and a target device. The method also includes obtaining motion information based on movement of the electronic device. The method further includes identifying first location information based on the motion information and the channel information. Additionally, the method includes identifying second location information based on the orientation of the electronic device and the AoA information. The method also includes determining whether the electronic device is in motion. The method further includes determining whether the target device is within the FoV or outside the FoV of the electronic device based in part on the first location information in response to determining that the electronic device is not in motion or the second location information in response to determining that the electronic device is in motion.

A frequency correction for frequency difference of arrival geolocation of transmitted target signals may be provided. A frequency of a target signal may be determined at a first collector based upon a first reference timebase source. A frequency of the target signal may be determined at a second collector based upon a second reference timebase source. An observed frequency of a reference carrier signal based upon the first reference timebase source may be determined at the second collector based upon the second reference timebase source. A relative timebase error between the first collector and the second collector may be calculated based upon a difference between the intended frequency of the reference carrier signal and the observed frequency of the reference carrier signal. A corrected frequency difference for the target signal may be calculated based upon the relative timebase error and a proportional scaling factor.

According to an embodiment, a communication apparatus acquires tag data of each wireless tag at a plurality of positions of a moved antenna via an antenna and inputs the tag data into a learned model. The communication apparatus acquires, on the basis of the input of the tag data of each wireless tag into the learned model, data indicating a level regarding the range in which each wireless tag is present from the learned model. In addition, the communication apparatus controls, in a case where the levels of the plurality of wireless tags acquired on the basis of one or more measurement processes for a plurality of wireless tags do not satisfy a condition, a measurement process involving a change of a measurement aspect with respect to the plurality of wireless tags.

Methods, devices and systems for generating enhanced location information on or about a wireless device. A fixed wireless device (e.g., fixed infrastructure device) may be configured to determine its current location based on location information received from one or more other devices. For example, the fixed wireless device may determine its current three-dimensional location based on latitude coordinate values, longitude coordinate values, and altitude coordinate values received from a plurality of the devices that are in proximity to the fixed wireless device. The fixed wireless device may then dynamically determine whether the fixed wireless device should be included in a telecommunication resource lease based on its determined current location. The fixed wireless device may allocate its available radio frequency resources use by devices that subscribe to a different network in response to determining that it should be included in the telecommunication resource lease.

The methods comprise: generating Inertial Reference Measurement Data (“IRMD”); reading RFID inventory tags by an RFID reader; processing IRMD to determine an RFID reader orientation and position estimates at a time of each RFID inventory tag read; defining cones associated with each RFID inventory tag; mapping the cones to a model; analyzing the model to identify a set of cones which overlap each other and are associated with reads for a respective RFID inventory tag; and deriving a position estimate for the respective inventory tag based on intersecting portions of the cones in the set of cones. Each cone has: a vertex which is the RFID reader position estimate at a respective time; and an angle which is in inverse proportion to a signal strength of a signal received from a respective RFID inventory tag.

A method of determining a location of a base station includes: receiving, at a mobile device from a location server, a base station identifier (BSID) of the base station and two or more candidate locations of the base station; receiving a signal, at the mobile device from the base station identified by the BSID; and selecting, at the mobile device, a particular candidate location from the two or more candidate locations based on a characteristic determined from the signal. A method of identifying an actual location of a base station includes: transmitting, from a location server to a disambiguating mobile device, a base station identifier (BSID) of the base station and two or more candidate locations of the base station; and receiving, at the location server from the disambiguating mobile device, an indication of the actual location of the base station from among the two or more candidate locations.

A method enables automatic determination that an area covered by an Access Point (AP) of a Wi-Fi Radio Access Network (RAN) overlaps with a cell of a 3.sup.rd Generation Partnership Project (3GPP) RAN. The method comprises, at an entity of the Wi-Fi RAN, obtaining a 3GPP identifier related to a user terminal that is attached to the Wi-Fi RAN and an identifier for an AP of the Wi-Fi RAN to which the terminal is attached. The method further comprises, at the entity, generating and sending a Location Service Request including the 3GPP identifier to a Location Services (LCS) Server associated with the 3GPP RAN, receiving a Location Service Response from the LCS Server that includes information identifying a cell of the 3GPP RAN in which the user terminal is located, and causing storage of an association between the identified Wi-Fi AP and the identified 3GPP cell.

Methods and apparatus for determining an angle of arrival in a radar warning system that uses tracking to provide a more accurate angle of arrival than conventional systems. In exemplary embodiments, angle of arrival and range are mapped from measured body angles to a 3D coordinate system where modern tracking techniques are applied to improve accuracy and stabilization of measurements, then mapped back into body angles for display.
