  • 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.

  • Patent number: 11018933
    Abstract: The present disclosure is directed to systems and methods that enable adjusting of focal point of maps displaying network sites of an enterprise network for access by an authorized network controller, based on network provider's access privilege. In one aspect a method includes receiving an access request to access a network controller management dashboard for managing network sites of a network; determining an access privilege associated with the access request; identifying one or more network sites for the access request based on the access privilege; and providing an interactive visual rendering of the one or more network sites by adjusting a focal point of a map of the network sites to display only the one or more network sites.

  • Publication number: 20210153026
    Abstract: Location-aware spatial reuse may be provided. First, an Overlapping Basic Service Set (OBSS) transmission to be received at a device may be detected by a first Access Point (AP). Then the location of the device may be determined. Next, based on the determined location, it may be determined that the device is out of range of the first AP. Then, in response to determining that the device is out of range of the first AP, the first AP may perform an OBSS Packet Detect (PD) based Spatial Reuse (SR) transmission without reducing a transmit (Tx) power for the transmission.

  • Publication number: 20210119893
    Abstract: Inter-protocol interference reduction for hidden nodes may be provided. A first service end point may determine that an inter-protocol interference is present on a channel. Next, an initial packet failure count value on the channel may be determined. A transmit (Tx) power for selected packets may then be increased until a subsequent packet failure count value on the channel is less than the initial packet failure count value.

  • Publication number: 20200336922
    Abstract: Pattern recognition and classification of packet error characteristics for Multi-user Multiple Input Multiple Output (MU-MIMO) optimization may be provided. First, a packet error characteristic data of a channel for a Downlink (DL) Multi-user (MU) group may be received. Next, the received packet error characteristic data may be provided as input data to a classifier model. Then, in response to providing the received packet error characteristic data as the input data to the classifier model, output data may be received from the classifier model. The output data may indicate at least one probability value corresponding to at least one channel effect. An optimization for improving performance of DL MU-MIMO in the presence of the at least one channel effect may then be performed when the at least one probability value is above or below a predetermined level.

  • Patent number: 10743226
    Abstract: In one embodiment, a service receives radar data regarding usage of one or more wireless channels by a radar. The service populates a database of radar features with the received radar data. The service trains, using the database of radar features, a machine learning-based model to predict channel usages by the radar. The service causes a wireless access point to change to a different wireless channel, based on the predicted channel usages by the radar.

  • Publication number: 20200153540
    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.

  • Patent number: 10541778
    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. Each subchannel corresponds to a distinct frequency chunk with a respective plurality of subcarriers. Radar is detected on a first subchannel. In response, a selection is made between (i) redefining the channel and (ii) puncturing the first subchannel while continuing to use all other subchannels. Puncturing the first subchannel includes muting subcarriers on the first subchannel. Redefining the channel includes removing multiple subchannels from the channel. The selection is based at least in part on one or more factors that provide indications as to whether puncturing would be efficient and/or effective. The access point continues to communicate wirelessly with the one or more client devices in accordance with the selection.

  • Publication number: 20200015220
    Abstract: Bypassing radar in wide Dynamic Frequency Selection (DFS) channels utilizing puncturing may be provided. A first client device may be classified as eligible for puncturing and a second client device may be classified as not eligible for puncturing. Next, it may be determined that a subchannel in a bandwidth range should not be used. Then, in response to determining that the subchannel in the bandwidth range should not be used, the first client device may be steered to a first subset of the bandwidth range and the second client device may be steered to a second subset of the bandwidth range. The second subset of the bandwidth range may be smaller than the first subset of the bandwidth range.
