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: 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.

Abstract: Systems and methods for power save aware resource unit allocation include sending, by an access point to a station, a beacon indicating that the station has data buffered at the access point, wherein the station is in a power-save mode, sending, by the access point after sending the beacon, an Orthogonal Frequency Division Multiple Access (OFDMA) trigger to the station, wherein the OFDMA trigger causes the station in the power-save mode to send PS-POLL using OFDMA, receiving, by the access point and from the station, a PS-POLL frame using OFDMA.

Abstract: Methods for assigning effective isotopic radiated power to an access point in a wireless network are provided. In one aspect, a method includes determining weights for neighboring access points in a wireless network based on channel frequency and basic service set color assignments. For a particular access point, a first path loss based on the determined weights and a second path loss based on the neighboring access points are calculated. First and second effective isotopic radiated power values are calculated based on the respective first and second path losses. The effective isotopic radiated power of the particular access point is adjusted based on the lower of the first and second calculated effective isotopic radiated power values. Systems and machine-readable media are also provided.

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.

Abstract: Examples described herein mitigate adjacent channel interference for dual radios of a network device. Examples described herein may associate, by a network device, a first client device with a first radio of the network device, associate, by the network device, a second client device with a second radio of the network device, determine that the first and second client devices are within a steering threshold, and based on the determination that the first and second client devices are within the steering threshold, steer, by the network device, the second client device from the second radio to the first radio. Examples described herein may communicate, using the first radio of the network device, with the first and second client devices.

Abstract: Systems and methods are provided for synchronizing uplink (UL) and downlink (DL) traffic. In particular, frames associated with Quality of Service (QoS}-sensitive traffic flows to be transmitted in a first direction are prioritized commensurate with frames to be transmitted in a second direction, different/opposite to that of the first direction. For example, UL traffic flows can be prioritized based on DL traffic flows, where the traffic flows belong to the same application flow, and vice versa, where DL traffic flows can be prioritized based on UL traffic flows for the same application flow. In this way, end-to-end QoS can be achieved.

Abstract: Examples of techniques for handling fine time measurement ranging requests are described. In an example, an access point (AP) may receive a ranging request for initiating a Fine Timing Measurement (FTM) session. The AP may modify a channel width of a Wireless Local Area Network (WLAN) channel on which the AP is operating from a first channel width to a second channel width for performing the FTM session, where the second channel width is greater than the first channel width. In response to completion of an FTM burst associated with the FTM session, the AP may restore the channel width of the WLAN channel to the first channel width for performing non-FTM operations of the AP.

Abstract: Examples of triggered single user (SU) transmissions are described. In an example, an access point (AP) may send a SU trigger frame to a client device for initiating a data transmission by the client device. The AP may detect whether the data transmission is initiated within the Short Interframe Spacing (SIFS) after the SU trigger frame is sent. Responsive to detecting that the data transmission is not initiated within the SIFS, the AP waits for the client device to initiate the data transmission within a predefined time interval after the SIFS. Responsive to detecting that the data transmission is not initiated within the predefined time interval, the AP repurposes the channel access after the predefined time interval is elapsed. Responsive to detecting that the data transmission is initiated within the predefined time interval, the AP repurposes channel access after one of an expiration of a maximum transmission opportunity (TXOP) duration and a completion of the data transmission, whichever is earlier.
