Abstract: In one embodiment, a device assigns a first radio of an access point in a wireless network to a client serving role and a second radio of the access point to a channel monitoring role. The device associates a wireless client with the first radio. The device determines that the wireless client is a low bandwidth client. The device switches the wireless client from the first radio to the second radio of the access point assigned to the channel monitoring role.

Abstract: Systems and methods herein can analyze a bandwidth restriction in a communication stream of an Access Point (AP). Then, based on the bandwidth restriction, the AP can determine a lower amount of wireless bandwidth to provide to station wireless communicating to the AP. The AP can then modify a bandwidth allocation assigned to the station based on the lower amount of wireless bandwidth.

Abstract: In one embodiment, a supervisory device for a wireless network classifies each client of a set of access points in the wireless network as either an Internet of Things (IoT) device or a non-IoT device. The supervisory device selects, for each of the access points in the set, a channel width based on the classifications of its clients. The supervisory device assigns, for each of the access points in the set, one or more wireless channels for use by that access point, based on the selected channel width for that access point. The supervisory device instructs the access points in the set to use their assigned channels to communicate with their clients.

Abstract: In one embodiment, a technique for automatic classification and enforcement of low-bandwidth 20 MHz-only Internet of Things (IoT) devices is provided. An access point in communication with a plurality of devices may classify one or more client devices of the plurality as low-bandwidth or 20 MHz-only devices. The access point may allocate a subset of resource units (RUs) in a channel (e.g., a 20 MHz-wide channel) to the one or more client devices. The access point may then exchange data with the one or more client devices using the subset of RUs.

Abstract: Mitigation of active link alternation by multi-link devices (MLDs) may be provided. First, at least first and second links may be established between an Access Point (AP) MLD and an associated MLD client. The first link may be active, while the second link may be inactive. A set of traffic load data associated with the links may be collected before and after transmission of a Basic Service Set (BSS) load report to the MLD client. The report may include a traffic load on the second link prior to transmission, where the second link is less loaded than the first link. Based on the collected traffic load data, an active link alternation from the first to the second link by the MLD client responsive to receiving the report may be detected. One or more methods for BSS load report management may then be applied to mitigate future active link alternation.

Abstract: In dense Wireless Local Area Network (WLAN) deployments, Access Points (APs) in other Extended Service Sets (ESSs) can be hidden (a first AP does not receive signals from a third AP). However, these APs in other ESSs can still interfere with communications between the third AP and the devices communicating with the first AP. To improve service to that device in that situation, the first AP needs information about the third AP in the first AP's decision making processes. In these situations, a second AP, in contact with the third AP, can share information about the third AP with the first AP so that the first AP can avoid colliding with the third AP.

Abstract: Seamless client roaming for Multi-Link Device (MLD) clients may be provided. First, a Traffic Identifier (TID)-to-link map may be established by an Upper Service Access Point (U-SAP) of a multi-AP MLD entity that assigns subsets of TIDs to at least two links of the entity. For example, a client device logically associates with the U-SAP, while the client device physically connects to a first and second AP of the entity on a respective first and second link, where the first and second AP include first and second Lower Service Access Points (L-SAPs) and are non-collocated. Next, using the map, data received at the U-SAP is directed over one of the two links for transmission to the client device. Further, frame aggregation and block acknowledgment functions may be performed by one of the first or second L-SAP based on whether data transmission is over the first or second link.

Abstract: Management of radio resources of a wireless network according to a Flexible Radio Assignment (FRA) mode may be provided. For each Access Point (AP) of the wireless network: a type of AP may be identified including determining whether each AP has Multi-Link (ML) capability, and when the FRA mode is for performance, a bias may be applied to each ML capable AP to reduce a likelihood of a radio of each ML capable AP being identified as a redundant radio. For each Client Device (CD) of the wireless network, an identification of whether each CD has ML capability may be made, and a radio configuration of at least one ML capable AP may be tailored to support one or more ML capable CDs.

Abstract: Systems and methods herein can analyze a bandwidth restriction in a communication stream of an Access Point (AP). Then, based on the bandwidth restriction, the AP can determine a lower amount of wireless bandwidth to provide to station wireless communicating to the AP. The AP can then modify a bandwidth allocation assigned to the station based on the lower amount of wireless bandwidth.

Abstract: Techniques for a machine learning event-driven radio resource management (ED-RRM) module which provides analysis of interference events in a network system are described. The network system reacts to the detection of interference in a network system and uses multiple input parameters to determine a type of device creating the interference, a predicted duration of the interference, and an ED-RRM decision on whether to activate the radio resource management (RRM) processes to alter the network transmission or block the RRM processes to conserve system resources for the network system.
