  • Patent number: 11304048
    Abstract: Example implementations relate to partitioning a radio into chains to scan channels. In some examples, a network device may comprise a processing resource and a memory resource storing machine-readable instructions to partition a default radio of the network device into a service chain and a scan chain in response to a scan request, scan a particular channel with the scan chain to discover devices operating on the particular channel of a network, and combine the service chain and the scan chain into the default radio.

  • Publication number: 20220110052
    Abstract: The full efficiency gains of the Target Wake Time (TWT) mechanism specified in the 802.11ax standard may not be realized when stations associated to an access point (AP) are spread across multiple Base Station Service Identifiers (BSSIDs). In such a scenario, TWT as conventionally utilized/specified in the 802.11ax standard, cannot properly coordinate sleep/wake schedules for stations due to associating to different BSSIDs. Accordingly, various embodiments are directed to grouping stations associated to multiple BSSIDs of an AP to allow for the synchronization (or staggering) of TWT, and facilitate multi-user transmissions, both in the uplink and downlink directions.

  • Patent number: 11277850
    Abstract: Systems and methods for grouping client devices for uplink multi-user transmission are provided. Client device groups may be determined based on at least one of traffic compatibility/similarity, client device class compatibility/similarity, and uplink pathloss similarity. A target received signal strength measured by an AP with which client devices in the client device groups communicate and an appropriate modulation coding scheme rate to be used by the client devices may be determined and set for the client devices. The modulation coding scheme rate can be adjusted based on feedback regarding successful data packet reception at the AP from each of the client devices.

  • Publication number: 20220029668
    Abstract: Systems and methods are provided for optimizing channel bandwidth while increasing downlink multi-user, multiple-input, multiple-output (DL MU-MIMO) gain. Depending on the access point (AP) platform, for example, APs exhibit certain characteristics regarding DL MU-MIMO gain as a function of the number of DL MU-MIMO clients associated to the AP. Accordingly, APs can be configured to operate in accordance with an algorithm that checks the number of DL MU-MIMO capable clients are associated to an AP, and dynamically switch between single- and dual-radio modes of operation to take advantage of those DL MU-MIMO gains.

  • Publication number: 20210409957
    Abstract: Systems and methods for partitioning radio spectrum in an AP to support a mixed client environment while maintaining efficient 802.11ax transmissions is provided. Clients in a zone may be categorized into 802.11ax and legacy clients, and those clients may further be categorized into a majority population and a minority population. Assignment of the minority and majority populations can be effectuated by considering the number of available channels to be assigned to each population of client devices, as well as steering load/cost and a client device's ability to be steered to another channel. Moreover, assignment of the minority and majority populations can take into account maintaining a particular client-channel density.

  • Publication number: 20210409961
    Abstract: Systems and methods are provided for optimizing the channel switching process in an access point. Periodic background scanning of a current channel on which a radio is operating to determine channel utilization can be used to generate a ranked channel list from which to select an alternative channel to which the radio can migrate, for example, in the event of a radar signal(s) being detected on its current channel. To maintain connectivity for clients, the clients may be temporarily transitioned to a non-DFS channel while an isolated/dedicated radio chain is used to perform the requisite Channel Availability Check (CAC) assessment on a DFS channel if the radio, based on the ranked channel list, selects a DFS channel as the alternative channel.

  • Publication number: 20210385220
    Abstract: Operation of a wireless network access point (AP) to communicate with a first set of one or more wireless client devices using a wireless protocol in which spatial reuse of channels is supported via at least a dynamically configurable basic service set (BSS) identifier of the wireless AP. The BSS identifier is utilized to identify overlapping BSSs (OBSSs). A first set of one or more wireless client devices communicate using a wireless protocol in which spatial reuse of channels is supported via at least a dynamically configurable BSS identifier of the wireless AP. The BSS identifier is utilized to identify OBSSs. Unauthorized network activity is detected based on the BSS identifier and a received BSS identifier associated with the received transmissions. A dynamic adjustment is made to one of the BSS identifiers of the AP or the received BSS identifier in response to detected unauthorized network activity.
