Abstract: A system and method for optimizing a channel sounding procedure of a multi-link device (MLD) is disclosed. The improved channel sounding procedure disclosed herein involves an MLD requesting channel sounding information from a group of receivers on a first channel representing a first physical frequency, but receiving channel sounding information from a subgroup of the receivers on one or more other channels representing different physical frequencies. In this manner, the channel sounding procedure on a specific link of an MLD is optimized by offloading some of the sounding process to a different radio link that is also operational for the MLD as part of the same association context.

Abstract: Systems and methods for power save aware resource unit allocation include sending, by an access point to a station, a beacon indicating that the station has data buffered at the access point, wherein the station is in a power-save mode, sending, by the access point after sending the beacon, an Orthogonal Frequency Division Multiple Access (OFDMA) trigger to the station, wherein the OFDMA trigger causes the station in the power-save mode to send PS-POLL using OFDMA, receiving, by the access point and from the station, a PS-POLL frame using OFDMA.

Abstract: Examples described herein mitigate adjacent channel interference for dual radios of a network device. Examples described herein may associate, by a network device, a first client device with a first radio of the network device, associate, by the network device, a second client device with a second radio of the network device, determine that the first and second client devices are within a steering threshold, and based on the determination that the first and second client devices are within the steering threshold, steer, by the network device, the second client device from the second radio to the first radio. Examples described herein may communicate, using the first radio of the network device, with the first and second client devices.

Abstract: Systems and methods for providing enhanced Quality of Service (QoS) network transmissions can be based on an application sub-class or a user class. Systems and methods can include inspecting the information packet having a network level QoS field having a first network level QoS portion and a second network level QoS portion, determining an application sub-class or user class associated with the information packet, tagging the first network level QoS portion of the information packet according to a first network level QoS value, tagging the second network level QoS portion of the information packet according to a traffic priority indication and to a determined application sub-class or user class, and queuing the information packet for transmission from a network element based on the tagged first network level QoS portion and the second network level QoS portion.

Abstract: Systems and methods are provided for optimizing the channel switching process in an access point. Periodic background scanning of a current channel on which a radio is operating to determine channel utilization can be used to generate a ranked channel list from which to select an alternative channel to which the radio can migrate, for example, in the event of a radar signal(s) being detected on its current channel. To maintain connectivity for clients, the clients may be temporarily transitioned to a non-DFS channel while an isolated/dedicated radio chain is used to perform the requisite Channel Availability Check (CAC) assessment on a DFS channel if the radio, based on the ranked channel list, selects a DFS channel as the alternative channel.

Abstract: An example network information aggregator is disclosed. The network information aggregator includes a network interface, a memory, and processing circuitry. The processing circuitry is to receive a machine learning model trained using initialization data from a model creation device. The processing circuitry is also to generate a device steering rule to steer a client device from a first radio to a second radio using the machine learning model. The processing circuitry is also to send a steer command to the first radio.

Abstract: Example methods and apparatus to generate recommendation(s) for access point association by a client device are disclosed. An example method includes calculating an effective uplink data rate for the client with respect to a first access point based on a) an uplink data rate and b) a percentage of uplink airtime available to the client. The example method includes calculating a first effective downlink data rate with respect to the first access point based on a) a downlink data rate for and b) a percentage of downlink airtime available to the client. The example method includes computing a first metric for the first access point based on the first effective uplink data rate, the first effective downlink data rate, and a noise floor scaling factor. The example method includes generating an access point recommendation by comparing the first metric and a second metric for a second access point.

Abstract: Systems and methods are disclosed for generating a client device fingerprint model and identifying client devices using the model. Identifying client devices includes monitoring traffic transmitted over a wireless network to an unknown first client device, the traffic using at least one value of at least one wireless network operational parameter; determining, for each at least one value of the at least one wireless network operational parameter, a respective probability of successful packet reception at the first client device; comparing each probability to a data model representing probabilities of successful packet reception at each of a plurality of known second client devices for each of a plurality of values of the wireless network operational parameter; and associating at least one of the labels of the second client devices with the first client device based on the compare.
