Abstract: A device in an adaptive channel access system may include a processor that is configured initiate access of a channel, and perform a first jammer detection on the channel. The processor is configured to, when a jamming device is detected on the channel, access the channel with a channel occupancy time set to a first duration of time. The processor is configured to, when no jamming devices are detected: access the channel with the channel occupancy time set to the second duration of time that is greater than the first duration, while accessing the channel with the channel occupancy time set to the second duration of time, perform a second jammer detection on the channel, and when the jamming device is detected, cease to access the channel prior to the expiration of the second duration of time, otherwise continue to access the channel without re-initiating access of the channel.

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.

Abstract: Exemplary embodiments include a method performed by a wireless device configured as a slave in a first piconet and configured as a master in a second piconet. The method includes determining whether the wireless device has data to transmit over the second piconet to an other wireless device, determining an availability of a full slot in a first piconet schedule, selecting a data transmission scheme based on the availability of the full slot in the first piconet schedule and transmitting the data via the second piconet to the other wireless device in accordance with the selected data transmission scheme.

Abstract: A host device is configured to increase the power output by an internal amplifier of its wireless chipset in response to requests from a remote device. Once the internal amplifier has reached its maximum power, further requests for power increases from the remove device do not similarly lead to automatic power increases being delivered by a external amplifier of the host device. Rather, the host device determines the strength of the link between it and the remote device. If the signal strength is too low, it is an indication that the signal power output by the remote device may not be sufficient to maintain the link and that any further increases in signal power by the host device will have little or no effect on the link. However, if the signal strength from the remote device is sufficient, the host device determines an error rate between it and the remote device. If the error rate is sufficiently low to maintain the link, then the host device will not further increase its signal output power.

Abstract: A host device is configured to increase the power output by an internal amplifier of its wireless chipset in response to requests from a remote device coupled via a data link. Once the internal amplifier has reached its maximum power, the host device may determine the strength of the data link between it and the remote device. If the strength is low, it is an indication that further increases in signal power by the host device may have little effect on the link. If the signal strength from the remote device is sufficient, the host device determines an error rate. If the error rate is sufficiently low, the host device will not increase its signal output power. However, if the error rate is too high, the host device may increase power from its external amplifier to improve the error rate of the data link.

Abstract: To establish a connection between electronic devices some embodiments include a system, method, and/or computer program product for password pairing user-interface devices in wireless proximity. A first electronic device (e.g., a keyboard) transmits an advertising packet, and receives a password, where the password has been generated by a second electronic device (e.g., a smartphone) and the password enables pairing between the first electronic device and the second electronic device. The first electronic device transmits a message including the password to the second electronic device, where the second electronic device is within a predefined range of the first electronic device. In some embodiments the first device receives a command from the second electronic device to transition to a discovery mode, transitions to the discovery mode, and transmits a confirmation to the second electronic device that the first device is in the discovery mode.
