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: 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: 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.
