    Abstract: Dynamic antenna switching based on weighted signal to noise ratio (SNR). A wireless device may include multiple antennas. SNR at each active antenna may be calculated. An antenna-specific weight may be applied to each antenna's SNR. The antenna-specific weights may further be radio specific and/or transmit or receive specific in some cases. Antenna selection (possibly just for a specific radio and/or for transmit or receive operations, depending on the specificity of the antenna weights), including potentially switching which antenna is used, may be based on the resulting weighted SNR values for each antenna. If the antenna-specific weights are radio specific and/or transmit or receive operation specific, the method may be performed multiple times with different antenna-specific weights to select antenna(s) for different radios and/or for other operations.

    Abstract: Apparatus and methods for provisioning wireless devices for operation in one or more networks. In one embodiment, a provisioning service may provide access client (e.g., Subscriber Identity Module) data to a secure element in the wireless user device. The device may be preloaded with a provisioning SIM profile. The device may use the provisioning profile to roam onto a carrier, and communicate with a provisioning service, which may present the user with a list of available wireless carriers, such as carriers that service the user's current geographic location. In response to a user selection, the provisioning service may load a SIM profile associated with the selected carrier onto the secure element. The loaded SIM profile can be used to obtain wireless service from the selected carrier. The user may add multiple SIM profiles, and/or may delete SIM profiles.

    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: 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: Embodiments are disclosed for terahertz spectroscopy and imaging in dynamic environments. In an embodiment, a transmitter of an electronic device emits a continuous electromagnetic (EM) wave in the terahertz (THz) frequency band into a dynamic environment that includes a transmission medium that changes over time. A receiver of the electronic device, receives an EM wave reflected off an object in the environment and determines a spectral response of the reflected EM wave. The spectral response includes absorption spectra at a frequency in the THz frequency band that is indicative of a known target transmission medium. The absorption spectra of the target transmission medium and a path length of the reflected EM wave signal are used to obtain the concentration level of the target transmission medium from a reference library of known concentration levels.
