Abstract: Optimization of radio communications of a wireless network of a local site may be provided. A probe frame or an association frame may be received from a Client Device (CD) operating in the local site that identifies at least one operating class and Multi-Link (ML) capability information of the CD. Channel information of at least one Access Point (AP) having ML capability in the local site may be embedded in a probe response frame or in an association response frame based on the at least one operating class and the ML capability information of the CD. The probe response frame or the association response frame that includes the channel information of the at least one AP having ML capability in the local site may be transmitted, as unicast, to the CD.

Abstract: Presented herein are techniques for using mobile client density to compensate for variations in path loss between neighboring access points. In one example, a device (e.g., wireless controller) determines one or more mobile client density variation trends in a wireless network location and determines one or more neighbor message power variation trends between at least first and second access points within the wireless network location over a time period. The device generates one or more correlation bias factors using the mobile client density variation trends and the neighbor message power variation trends over the time period. The device determines a path loss between at least the first and second access points using the correlation bias factor.

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: Spectrum management may be provided. A first Radio Frequency (RF) event metric may be received from a first service end point. The first RF event metric may comprise a time a first event occurred. A second RF event metric may be received from a second service end point. The second RF event metric may comprise a time a second event occurred. Then it may be determined that the time the first event occurred and the time the second event occurred are substantially congruent. Next, in response to determining that the time the first event occurred and the time the second event occurred are substantially congruent, the first service end point and the second service end point may be grouped in a first RF group thereby allowing frequency re-use across similar RF groups. Then different channels may be assigned to the first service end point and the second service end point.

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: Enhanced Radio Frequency (RF) management using active sensors may be provided. First, a plurality of user devices may be determined that a first active sensor is to act as an anchor for within a first portion of a Radio Frequency (RF) environment in which the plurality of user devices and the first active sensor are disposed. Next, RF environment data corresponding to the first portion of the RF environment in which the plurality of user devices are disposed may be collected. A report corresponding to the first portion of the RF environment in which the plurality of user devices are disposed may then be created based on the collected RF environment data. The report may be configured to aid in evaluating a link between at least one of the plurality of user devices and a first Access Point (AP). The created report may be provided to the first AP.

Abstract: Systems, methods, computer-readable media, and devices are disclosed for collecting access point telemetry. A first access point is identified that is associated with a single instance on a pod. A hash identifier is identified, where the hash identifier identifies a radio frequency (RF) neighborhood of the first access point based on a geographical location of the first access point. Subsequent access point members of the RF neighborhood are dynamically determined by dynamically assigning a second access point to the RF neighborhood, the dynamic assignment based on the second access point being within a threshold geographical location to the first access point. Telemetry from the second access point is directed towards the single instance on the pod, where the pod receives telemetry for all access points in the dynamically determined RF neighborhood.
