Abstract: Systems, methods, and computer readable mediums for persistent TWT sessions include establishing, by an access point, a plurality of sessions with a plurality of stations, wherein one or more of the plurality of sessions comprise a target wake time (TWT), determining, by the access point, that a downtime event will occur before a TWT of a particular station of the plurality of stations, in response to the downtime event occurring during the TWT of the particular station, sending, by the access point, information associated with the plurality of sessions to a secondary device, after the downtime event, retrieving, by the access point, the information associated with the plurality of sessions from the secondary device, and reestablishing, by the access point using the information, the plurality of sessions.

Abstract: Example implementations relate to partitioning a radio into chains to scan channels. In some examples, a network device may comprise a processing resource and a memory resource storing machine-readable instructions to partition a default radio of the network device into a service chain and a scan chain in response to a scan request, scan a particular channel with the scan chain to discover devices operating on the particular channel of a network, and combine the service chain and the scan chain into the default radio.

Abstract: Example method includes: receiving, by an access point in a wireless local area network (WLAN), a plurality of wireless interference signals from an interfering device; deriving, by the access point, a fast Fourier transformation (FFT) pattern from the plurality of wireless interference signals received from the interfering device; transmitting, by the access point, the FFT pattern to a centralized repository that is remote to the access point; receiving, by the access point, a classifier from the centralized repository; and classifying, by the access point, the interfering device into a specific device type using the classifier received from the centralized repository based on the FFT pattern.

Abstract: Example implementations relate to a radio interrupt reboot. For example, an apparatus may include a first processing resource connected via an interface to a second processing resource. The first processing resource may execute instructions to receive an interrupt generated by a radio coupled to the second processing resource, increment a counter in response to receiving the interrupt during a configurable time interval, and determine that the counter has not been incremented during a threshold number of configurable time intervals. The first processing resource may execute instructions to reboot the first processing resource and the second processing resource in response to the determination that the counter has not been incremented during the threshold number of configurable time intervals.

Abstract: A method of adjusting a link in a wireless communication system is described. The method includes monitoring a communication channel by a network device in a wireless local area network. The method also includes detecting a signal identified as being transmitted by an unmanned aerial vehicle on the communication channel. The method further includes transmitting a signal with a duty cycle having a predetermined value in the communication channel and monitoring a received signal strength indicator of the signal identified from the unmanned aerial vehicle. In some embodiments, the transmitted signal includes one or more of an interference signal, a de-authentication frame, and a disassociation frame.

Abstract: Example implementations of an apparatus may comprise a first processing resource coupled to a second processing resource. The first processing resource may execute instructions to analyze an exception generated from the second processing resource, and identify a bit error on the second processing resource when the analysis of the exception indicates that the exception relates to the bit error on the second processing resource.

Abstract: Systems and methods are provided for adaptively enabling and disabling spatial reuse and adapting BSS color assignments based on various factors associated with a wireless network. A first AP in a wireless network can identify a second AP in a wireless network. The first AP and the second AP may be using the same wireless channel in the wireless network. The first AP can determine a signal strength, such as a received signal strength indicator (RSSI), associated with the second AP. The first AP can adapt its spatial reuse and BSS color assignment according to the signal strength and a signal strength threshold. By adaptively enabling and disabling spatial reuse and adapting BSS color assignments, the disclosed systems and methods provide for improved reuse of wireless mediums while avoiding collisions.

Abstract: Embodiments are directed to a fast path for acknowledgement frames in wireless networks. An embodiment of a storage medium includes instructions for operations including receiving frames at a network device via a wireless communication channel, each frame including a sequence number; holding the received frames in a reorder buffer to be reordered according to the sequence numbers of the received frames, wherein a frame is to be removed from the reorder buffer for delivery to a next process upon the sequence number of the frame equaling an expected next sequence number or upon expiration of a reordering timeout period for the frame; and, upon receiving an acknowledgment (ACK) frame, the ACK frame containing no data and having a sequence number that is later than any ACK frame that has been previously processed at the network device bypassing the reorder buffer for the ACK frame, and delivering the ACK frame to the next process, and maintaining an order position for the ACK frame in the reorder buffer until the reordering timeout period expires for the ACK frame.
