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.

Abstract: A network controller may include a memory and a processor. The memory may include instructions executable by the processor to receive a message from an access point. The message may comprise an interference event detected on a particular channel, wherein the particular channel is part of a particular channel list associated with the access point and stored at the network controller in a wireless local area network (WLAN). The memory may further include instructions executable to remove the particular channel from the particular channel list associated with the access point. The memory may further include instructions executable to determine a channel plan for a plurality of access points in the WLAN based on a corresponding plurality of channel lists including the particular channel list and deploy the channel plan to the plurality of access points.

Abstract: A method related to selecting a channel bandwidth may include partitioning the plurality of networks into a plurality (P) of local radio environments and identifying, for the P local radio environments, an available channel bandwidth set comprising a plurality of channel bandwidth values. The method may also relate to determining whether the plurality of channel bandwidth values provide a frequency reuse distance that is greater than a threshold frequency reuse distance, wherein the frequency reuse distance is estimated based at least on the pathloss measurement and, based on a determination that at least one of the plurality of channel bandwidth values provides the frequency reuse distance that is greater than the threshold frequency reuse distance, configuring a channel plan for the plurality of networks with a channel bandwidth value from the at least one of the plurality of channel bandwidth values.

Abstract: Systems and methods for assigning default an alternative BSS colors in a wireless local area network (WLAN) including a network graph representing radio neighbors include assigning a frequency range and EIRP for each radio represented in the network graph; generating a subgraph of radios operating at the same frequency range; for the subgraph, determining a minimum number of basic service set (BSS) colors required to BSS color the subgraph without BSS color conflict; based on the minimum number of BSS colors, assigning a default BSS color to each radio in the subgraph to avoid BSS color conflict among radios in the subgraph; based on remaining BSS colors, assigning one or more alternative BSS colors to each radio in the subgraph.

Abstract: Systems and methods for calculating uplink pathloss in a wireless local area network are provided. Uplink pathloss between an access point and client device operating in the wireless local area network can be calculated based on determining an effective maximum transmit power. Based on the effective maximum transmit power, and known uplink power headroom, a current transmit power of the client device can be determined. Based on the current transmit power of the client device, uplink pathloss can be determined. If the operating conditions and/or characteristics of the client device and/or wireless local area network change, the uplink pathloss may be re-evaluated.

Abstract: An example access point is described that includes a wireless transceiver, processing circuitry, and a non-transitory computer-readable medium comprising instructions. The instructions, when executed on the processing circuitry cause the processing circuitry to: receive a trained machine learning model that determines whether signals include interference patterns characteristic of a category of interference sources, receive a first signal including a first interference pattern, determine that the first interference pattern is an interference pattern characteristic of the category of interference sources, transmit information about the first signal including attributes of the first interference pattern and the determination that the first interference pattern is an interference pattern characteristic of the category of interference sources to the model training device, and receive an updated trained machine learning model that is updated based at least on the transmitted information about the first signal.
