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: 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.

Abstract: Methods and apparatus enabling a mobile device to receive paging notifications from multiple networks. In one embodiment of the present invention, a first device connected to a first network momentarily ignores the first network, to monitor a second network instead. The first device identifies and prioritizes a list of applications of the first network; the prioritized listing allows the first device to preempt one of its lower priority tasks to monitor the second network for paging messages instead. The described methods and apparatus enable e.g., GSM paging for Class B cellular devices which are connected to GPRS NMO-2 type networks. The Class B cellular device can ignore certain GPRS data (which is tolerant to error), to decode GSM paging channels, which would otherwise be missed.

Abstract: Electronic devices may communicate with each other using a “conducted RF link.” Such a conducted RF link is essentially a link that utilizes a conductor or cable that facilitates communication between electronic devices. Instead of the conductor carrying a traditional signal, it carries a modulated RF signal, such as those produced by a typical wireless RF radio like presently available WiFi/Bluetooth® cores.

Abstract: Devices at either end of a wireless communication link are each configured to support multiple different link settings. During communication, a device that is receiving data can monitor the signal quality and initiate a dynamic transition to a new link setting if performance of the current link setting falls below a lower threshold or exceeds an upper threshold. Dynamic link adaptation can be implemented within a wireless communication interface of the device and can be transparent to application and/or operating system software executing on the device.

Abstract: Apparatus and methods for authenticating and granting a client device (e.g., cellular telephone) access to a network. In one embodiment, a network service provider such as a cellular telephone company may distribute user access (e.g., Universal Subscriber Identity Module or “USIM”) credentials to a service manager via a USIM vendor. The services manager may maintain a list of authorized users. A user at a client may authenticate to the services manager. Once authenticated, the services manager may provide the user with a set of USIM credentials. When the user desires to use wireless network services, the user equipment may establish a wireless link between the user equipment and the network service provider. During authentication operations, the user equipment may use the USIM credentials to authenticate to the network service provider. Following successful authentication, the network service provider may provide the user equipment with wireless services.

Abstract: In order to establish a connection between electronic devices, after receiving an advertising packet from another electronic device, an electronic device compares a performance metric associated with the communication with the other electronic device with a threshold value. Based on the comparison, the electronic device provides pairing-intent information specifying a pairing intent for the electronic device and the other electronic device for presentation by the other electronic device. Moreover, after receiving additional pairing-intent information specifying the pairing intent from the other electronic device, the electronic device establishes the connection with the other electronic device when the additional pairing-intent information matches the pairing-intent information. For example, the pairing intent may include a gesture and/or a sequence of one or more characters, and the additional pairing-intent information may include: the sequence of one or more characters; accelerometer data corresponding to the gesture; and/or user-interface data corresponding to the gesture.

Abstract: In order to improve communication with another electronic device, during an advertising mode an electronic device (such as a smartphone) may transmit a packet with advertising information using a default transmit power level. Then, based on feedback about a performance metric associated with the communication from the other electronic device, the electronic device may selectively increase the transmit power level for a subsequent packet. Because this selective increase in the transmit power level may increase the overall power consumption, the change in the transmit power level may depend on a battery power level of the electronic device. However, the selective increase in the transmit power level may decrease the overall power consumption by reducing or eliminating retries.
