  • Patent number: 11159960
    Abstract: Systems and methods herein can synchronize 802.11ax Uplink (UL) and Downlink (DL) Orthogonal Frequency-Division Multiple Access (OFDMA) schedules between adjacent APs that have overlapping BSSs, which may not be solved by BSS coloring. The method includes several stages. First, the APs detect RF interference from APs with overlapping BSSs. Then, the APs conduct time synchronization between these APs. The various APs can then elect a master scheduler. The master scheduler creates and implements a master schedule between these APs to coordinate use of the radio resource.

  • Patent number: 11153761
    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.

  • Patent number: 11146982
    Abstract: The present disclosure provides systems and methods for dynamically adjusting cell coverage sensitivity to address asymmetry of wireless cells that affect upstream and downstream traffic mismatch. In one aspect, a method includes estimating, at a network controller, one or more packet demodulation thresholds for an access point; sending, by the network controller, the one or more packet demodulation thresholds to the access point; receiving, from the access point, collected statistic, the collected statistics being link performance characteristics between the access point and one or more endpoints associated with the access point measured by one or more sensors associated with the access point; updating, at the network controller, the one or more packet demodulation thresholds based on the collected statistics to yield an updated packet demodulation threshold; and configuring, by the network controller, the access point with the updated demodulation threshold.

  • Publication number: 20210297164
    Abstract: An access point allocates resource units within a first channel to mitigate interference from an adjacent second channel. The access point obtains a measure of signal strength corresponding to each wireless device attached to an access point, and assigns, for each wireless device, resource units with a first frequency band of the first channel to mitigate interference with a second frequency band of a second channel adjacent to the first channel. An assignment between a set of resource units and a particular wireless device is based on the measure of signal strength corresponding to the particular wireless device. The access point communicates with the wireless devices on the resource units.

  • Publication number: 20210289397
    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.

  • Patent number: 11122443
    Abstract: Wireless access point locations can be determined by processing a combination of wired and wireless telemetry. Wireless telemetry can be combined with backend network management information to isolate a set of access points within a radio frequency neighborhood cluster. Wired telemetry, including time domain reflectometer operations performed by a local switch, can be used to refine location estimates of the isolated set of access points. Trilateration can be used to pinpoint the access point locations and the pinpointed locations can be overlaid on a floor plan map.

  • Publication number: 20210235325
    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.

  • Publication number: 20210195562
    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.

  • Publication number: 20210144239
    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.

  • Publication number: 20210120397
    Abstract: A method performed by a system which manages station transition from a Wi-Fi access point includes sending, based on the station roaming to an edge-of-domain access point, a request to neighboring access points to the edge-of-domain access point for neighbor reports. The method includes receiving a cellular signal value from the station, comparing a first signal grade associated with the edge-of-domain access point to a second signal grade associated with the cellular signal value to yield a comparison and generating a link usability rating associated with a link between the station and the edge-of-domain access point. Based at least in part on the comparison and the link usability rating, the method includes transmitting a message to the station suggesting that the station roam from the edge-of-domain access point to a cellular network. An edge of the domain can also be dynamic and vary based on station characteristics.

  • Patent number: 10972943
    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.
