Abstract: 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.

Abstract: Multi-radio wireless network devices are capable of transmitting and/or receiving data from multiple radiofrequency (RF) networks at different bands. Total transmission power limitations may be in place due to, for example, safety reasons. As a result, active management of transmission power may be performed during simultaneous transmission in different bands and/or networks. In some embodiments, the management may take place on group-by-group basis and a network-by-network basis. Antennas may be grouped based on their relative positions and impact on radiation emitted by the devices.

Abstract: 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.

Abstract: Devices and systems useful in concurrently receiving and transmitting Wi-Fi signals and Bluetooth signals in the same frequency band are provided. By way of example, an electronic device includes a transceiver configured to transmit data and to receive data over channels of a first wireless network and a second wireless network concurrently. The transceiver includes a plurality of filters configured to allow the transceiver to transmit the data and to receive the data in the same frequency band by reducing interference between signals of the first wireless network and the second wireless network.

Abstract: A wireless power system may use a wireless power transmitting device to transmit wireless power to a wireless power receiving device. The wireless power transmitting device may have microwave antennas that extend along an axis in a staggered arrangement. In the staggered arrangement, the microwave antennas are positioned on alternating sides of the axis. Each microwave antenna is elongated along a dimension that is perpendicular to the axis. Multiple antennas may overlap a wireless power receiving antenna in the wireless power receiving device. Control circuitry may use oscillator and amplifier circuitry to provide antennas that have been overlapped by the wireless power receiving antenna with drive signals. The drive signals may be adjusted based on feedback from the wireless power receiving device to enhance power transmission efficiency. The system may have a wireless power transmitting device with inductive wireless power transmitting coils.
