Abstract: An access point in a wireless network communicates wirelessly with one or more client devices over a channel that includes a plurality of subchannels. Radar is detected on a first subchannel of the plurality of subchannels. It is determined to puncture the first subchannel, based on the detecting the radar on the first subchannel and based on one or more puncturing factors. The first subchannel is punctured, the puncturing comprising muting one or more subcarriers on the first subchannel.

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.

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 based on the correlation bias factor and data associated with neighbor messages sent between the first and second access points.

Abstract: A method and system for providing location services at a network edge is described. An AP can receive location information associated with a second AP in a location group. The AP can also receive client location data from the second AP and associated with a first client. From at least the received client location data, the AP can determine a location of the first client. The AP can then send the location of the first client to a location service.

Abstract: Parallel Redundancy Protocol (PRP) using non-overlapping Resource Unit (RU) groupings may be provided. A first computing device may associate to a first Access Point (AP) at a virtual Media Access Control (MAC) address. Next, the first computing device may associate to a second AP at the virtual MAC address. Then data from a data frame may be replicated to a first one or more RUs in a channel. The first one or more RUs may be assigned to the first AP. Data from the data frame may then be replicated to a second one or more RUs in the channel. The second one or more RUs may be assigned to the second AP and may not overlap the first one or more RUs.

Abstract: Client analytics-driven dynamic channel assignment may be provided. At a client, Radio Frequency (RF) channels may be scanned to detect access points of a network. A subset of the access points belonging to a same Extended Set Service (ESS) of the network may be determined based on data collected from the access points during the scan. For each access point in the subset, a Channel Quality Index (CQI) may be measured for an RF channel assigned to the access point, and a non-preferred channel report may be generated based on the CQI. The non-preferred channel report may be transmitted from the client to a network management system for use in dynamic channel assignment.

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: The present technology enables inter-network routing by dynamically optimizing data paths for traffic destined for wired clients attached to a wireless access point in a wireless mesh network with a plurality of wireless access points. The present technology can also influence steering of wireless device connections within the wireless mesh network when high amounts of data traffic are exchanged between nearby mesh wireless access points.
