Abstract: Electronic devices may be provided that contain wireless communications circuitry. The wireless communications circuitry may include radio-frequency transceiver circuitry and antenna structures. An electronic device may include a display mounted within a housing. A peripheral conductive member may run around the edges of the display and housing. Dielectric-filled gaps may divide the peripheral conductive member into individual segments. A ground plane may be formed within the housing from conductive housing structures, printed circuit boards, and other conductive elements. The ground plane and the segments of the peripheral conductive member may form antennas in upper and lower portions of the housing. The radio-frequency transceiver circuitry may implement receiver diversity using both the upper and lower antennas. The lower antenna may be used in transmitting signals. The upper antenna may be tuned using a tunable matching circuit.

Abstract: This application relates to systems, methods, and apparatus for testing operability of a mobile device with a reader device. In some embodiments, a testing system is set forth for automatically placing the mobile device proximate to the reader device in order to initiate a wireless transaction between the mobile device and the reader device. Depending on whether the mobile device is determined to be operable with the reader device, the testing system can automatically place the mobile device proximate to another reader device for testing. In this way, reductions in testing time can be manifested as a result of automating the testing process.

Abstract: In order to improve the quality of communication between electronic devices, one or more sub-channels used during communication between the electronic devices are dynamically modified based on one or more performance metrics and allowed transmit powers of the sub-channels. In particular, when the one or more performance metrics indicate that a distance between the electronic devices falls within a mid-range of distances, the one or more performance metrics may be used to guide selective changes to the sub-channels used during the communication based on the allowed transmit powers. The changes to the sub-channels used during the communication may increase, decrease or leave the total bandwidth unchanged. Moreover, by changing the sub-channels used during the communication, the allowed transmit power(s) of the sub-channel(s) used may be increased, which may improve the performance during the communication.

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: Wireless communication between two electronic devices may be used to determine a distance between the two devices, even in the presence of an otherwise-disruptive attacker. A wireless receiver system of one device may receive a true wireless ranging signal from a first transmitting device and a false wireless ranging signal from an attacker. The wireless receiver system may correlate the wireless signals with a known preamble sequence and perform channel estimation using the result, obtaining a channel impulse response for the wireless signals. The wireless receiver system may filter the channel impulse response for the plurality of wireless signals by removing at least part of the channel impulse response due to the false wireless ranging signal while not removing at least part of the channel impulse response due to the true wireless ranging signal. The receiver system may perform a wireless ranging operation using the filtered channel impulse response.

Abstract: A technique for reducing interference on conducted RF links involves a determination of active wireless channels in an electronic device. For example, the device can determine whether there are any active cellular, WiFi, and/or Bluetooth channels. If so, any active channels can be removed from a list of possible channels that can be used for generating the RF signals for the conducted RF link. If any idle channels remain available, one or more may be selected for use for the conducted RF link. Those idle channels having a higher offset from any active channels may be given a greater weight in the selection since they should be less likely to be subject to interference. If not, one of the least crowded active channels may be selected for use for the conducted RF link.

Abstract: A wireless communication device includes a number of radio-frequency (RF) antennas and one or more radio circuits. Each radio circuit includes a receive (RX) chain to process RX signals and a transmit (TX) chain to process TX signals. An RF switch network couples at least one RF antenna to at least one radio circuit. A baseband processor controls a configuration of the RF switch network. The baseband processor determines a plurality of parameters and controls the RF switch network based on at least one of the parameters. The parameters are determined during a training interval including at least an inter-frame space (IFS). The configuration of the RF switch network is based on the determined parameters and is employed for selection of an antenna to improve a link performance when used for communication of a next packet following the IFS.
