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.

Abstract: 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.

Abstract: 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.

Abstract: The present disclosure describes examples of the mechanism of a Supplemental Beacon. The Supplemental Beacon may be used as an additional beacon to an original main beacon in a Wi-Fi system. The Supplemental Beacon may be transmitted in a Short Interframe Space (SIFS) interval preceding the transmittance of the main beacon. Establishing set times of the Supplemental Beacon transmittance before the main beacon may allow client devices to wake up at consistent time intervals to receive data, and allow client devices to only remain awake for a short duration between the Supplemental Beacon transmittance and the main beacon transmittance before going back to sleep. The support of a Supplemental Beacon to the main beacon at fixed times of short duration before the main beacon that may allow the conservation of power of client devices and network devices in the Wi-Fi system, and increase productivity in the transmission of data.

Abstract: Systems and methods are provided for defining a split multi-link system. For example, the split multi-link system can define a multi-link device (MLD), where the MLD operates a first radio from a first AP of a plurality of APs and a second radio from a second AP of the plurality of APs through a Media Access Control (MAC) Service Access Point (SAP) of the split multi-link system. The first radio from the first AP and the second radio from the second AP may operate at different frequencies. The split multi-link system may also affiliate the first radio from the first AP and the second radio from the second AP with the MLD, where, using the MLD, the split multi-link system can transmit or receive one or more data frames from the MLD to a non-MLD or MLD client device using the first radio or the second radio.
