Systems and methods are provided for receiving data indicating a spatial distribution and 802.11ax capabilities of access point radios and of client devices in a network, assigning the access point radios as either first access point radios or second access point radios, the first access point radios conducting data transmission using an 802.11ax wireless standard and the second access point radios conducting data transmission using legacy wireless standards, based on the data, determining whether any of the client devices are to be steered to a different access point radio based on the 802.11ax capabilities of the client devices, and in response to determining that a client device is to be steered to a different access point radio, steering the client device to a first access point radio or a second access point radio.

Redistribution of 802.11ax capable client devices to radios to improve throughput and spectral efficiency

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.

Channel plan determination

An example non-transitory computer readable medium comprising instructions executable by a processor to: determine a channel distribution vector based on a channel priority for a plurality of available wireless channels within a wireless network; receive a set of constraints on a channel plan; determine a channel plan meeting the set of user defined constraints based on the channel distribution vector; and transmit the channel plan to a plurality of radios on the wireless network, wherein the channel plan comprises a channel assigned to each radio of the plurality of radios.

Determine channel plans

An example access point comprising: a memory; and a processor executing instructions stored in the memory to: determine a first interference event while operating on a first channel, wherein the first channel is designated to the access point in a global channel plan by a network controller based on a global view of a wireless network; switch to operate on a second channel from the first channel for a first amount of time in response to the first interference event; determine a second interference event of the same event type as the first interference event on the first channel, wherein the second interference event is the same event type as the first interference event; and switch to operate on the second channel from the first channel for a longer amount of time than the first amount of time, wherein the second channel is selected based on a local view of the wireless network by the access point.

Channel switching based on interference events

Examples of the present disclosure include: obtain data collected from a plurality of access points (APs) in a WLAN, including a current allocation of channels to radios of the APs according to a current channel plan; calculate a new channel plan which assigns a different channel to at least one of the radios; calculate a first metric that predicts better network performance achieved by the new channel plan than the current allocation of channels to the radios; determine whether the first metric exceeds a first predetermined threshold; and implement the new channel plan in response to determining that the first metric exceeds the first predetermined threshold.

Channel plans for wireless local area networks

An example method comprising: assigning at least one band mode specified in the band mode list to a radio of the identified node, assigning a dual band mode to a set of wireless nodes of the plurality of wireless nodes that each satisfy a baseline coverage when operating on a low frequency band of the wireless band mode, assigning a high frequency band mode to a set of wireless nodes of the plurality of nodes based on band capacity, assigning a channel to the radio of the node on the high frequency band based on a band capacity; and responsive to assigning the channel to the radio on the high frequency band, assigning a channel to each radio of the set of nodes on the low frequency band.

Assign band modes and channels to wireless nodes

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.
