Abstract: A mobile device may receive a plurality of polling messages with each polling message including an identifier of a particular access device transmitting the polling message. Each polling message of the plurality of polling messages may be transmitted during a polling phase. The mobile device may select a timeslot of a response phase of a communication session. The mobile device may transmit a response message during the timeslot of the response phase. The mobile device may receive, during a third phase, an assignment message including an assigned timeslot for a response phase of a future session. The mobile device may perform secure ranging with one or more access devices of the plurality of access devices during the future session using the assigned timeslot. The mobile device may provide an access credential to the one or more access devices based on a location determined using the secure ranging.

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: Techniques for ranging for a mobile device with one or more electronic devices using communication circuitry implementing a wireless protocol can include storing a schedule for a plurality of communication sessions. The technique can include broadcasting the advertising packets during a selected number of available time slots of a second time period, the advertising packets including information about the schedule for the plurality of communication sessions. After broadcasting an advertising packet during a selected time slot, the technique can include entering a reduced power state for the communication circuitry until a subsequent advertising packet is sent or a subsequent first time period for communicating the ranging packets as specified by the schedule. The technique can include exiting the reduced power state for the communication circuitry prior to the subsequent first time period. The technique can include transmitting a ranging packet via the wireless protocol according to the schedule.

Abstract: A mobile device can include ranging circuitry to determine distance to another mobile device. A first wireless protocol can establish an initial communication session to perform authentication and/or exchange ranging settings. A second protocol can perform ranging, and other wireless protocols can transmit content. In one example, the distance information can be used to display a relative position of another device on a user interface of a sending device. The user interface can allow a user to quickly and accurately select the recipient device for sending the data item. As other example, the distance information obtained from ranging can be used to trigger a notification (e.g., a reminder) to be output from a first mobile device or used to display a visual indicator on a receiving device. Proximity of a device (e.g., as determined by a distance) can be used to suggest recipient for a new communication.

Abstract: Two different wireless protocols can be used for ranging between a mobile device and an access control system (e.g., a vehicle). The first wireless protocol (e.g., Bluetooth®) can be used to perform authentication of the vehicle and exchange ranging capabilities between a mobile device (e.g., a phone or watch) and the vehicle. The second wireless protocol (e.g., ultra-wideband, UWB) can use a pulse width that is less than a pulse width used by the first wireless protocol (e.g., 1 ns v. 1 μs). The narrower pulse width can provide greater accuracy for distance (ranging) measurements.

Abstract: The subject system aggregates, or stitches, multiple component channel estimates to generate an aggregated wideband channel estimate that can be used to determine more accurate time of arrival estimations than those determinable from the individual component channel estimates. The subject system also provides for multipath detection on a single channel or an aggregated channel that may be used to facilitate an accurate time of arrival estimation. For example, information derived from the multipath detection may be used to supplement and/or enhance a time of arrival estimation algorithm. The subject system also provides a sounding protocol that allows devices to perform one or more signal exchanges to facilitate generating the aggregated wideband channel estimate and/or to facilitate performing the multipath detection. The protocol allows the devices to perform signal exchanges over one or more channels within a coherence time, and also provides for security mechanisms as well as failure recovery.
