摘要： Methods and devices are provided for allowing a mobile device (e.g., a key fob or a consumer electronic device, such as a mobile phone, watch, or other wearable device) to interact with a vehicle such that a location of the mobile device can be determined by the vehicle, thereby enabling certain functionality of the vehicle. A device may include both RF antenna(s) and magnetic antenna(s) for determining a location of a mobile device relative to the vehicle. Such a hybrid approach can provide various advantages. Existing magnetic coils on a mobile device (e.g., for charging or communication) may be re-used for distance measurements that are supplemented by the RF measurements. Any device antenna may provide measurements to a machine learning model that determines a region in which the mobile device resides, based on training measurements in the regions.

摘要： Systems, methods, and devices are provided to estimate angle of arrival of wireless signals. An electronic device may include two or more antennas that receive a wireless transmission. The wireless transmission includes a first frequency signal at a first frequency and a second frequency signal at a second frequency. The electronic device includes angle of arrival logic that may determine one or more angles of arrival of the wireless transmission to the electronic device using phase difference on arrival based on each of the first and second frequency signals.

摘要： Methods and apparatuses are presented to locate a wireless communication device. A target device may be out of range of a source device for normal ranging communications according to a first radio access technology (RAT), such as ultra wideband (UWB) communications. A source device may therefore modify communications according to the first RAT, to increase the transmit power, while removing the data payload. The target device may utilize the signal strength and angle of arrival of the modified communications to guide the user to move toward the source device, e.g., until the target device is within range to perform normal ranging communications. A second RAT, such as Bluetooth, may be used to communicate between the two devices while the target device is out of range of the first RAT. For example, the target device may use the second RAT to communicate to the source device to start/stop transmitting modified communications.

摘要： A user equipment (UE) including at least two antennas configured to allow the UE to communicate via a first connection. The UE selects a connection performance parameter associated with the first connection, generates historical measurement information for the at least two antennas based on the connection performance parameter, for the plurality of antennas, the historical measurement information indicating an expected performance associated with using a selected one of the at least two antennas for a packet transmission and selects, based at least on the historical measurement information, one of the at least two antennas for use in transmitting the packet.

摘要： A wireless network may include devices that wirelessly transmit and receive packets. Each packet may include a preamble, a start-of-frame delimiter, a physical layer header, a sequence of symbols between the start-of-frame delimiter and the physical layer header, and a data payload. The sequence of symbols may have a pattern that is resistant to spoofing attacks. A receiving device may have a correlator that correlates known symbols against the symbols in the sequence using overlapping three-symbol-length correlation windows. Early arrival peaks in the output of the correlator may be used to correct time stamp information in the packets and late arrival peaks corresponding to spoofed signals from an attacker may be ignored. Time stamp information may be processed to determine ranges between transmitting and receiving devices.

摘要： Methods and devices useful in performing precise indoor localization and tracking are provided. By way of example, a method includes locating and tracking, via a first wireless electronic device, a plurality of other wireless electronic devices within an indoor environment. Location ambiguity mitigation is performed using characteristics of signals received by a reference node used to generate a radio frequency map of electronic devices.
