Abstract: In one embodiment, a method comprises first causing, by a controller device, wireless access points (APs) to allocate first non-interfering wireless channels for a prescribed reliable data service for wireless client devices in a WLAN; second causing the wireless APs to allocate a second shared channel having a bandwidth that is at least twice the corresponding bandwidth of any of the first non-interfering wireless channels; allocating for each wireless client device a corresponding location service interval on the second shared channel for transmission of at least a corresponding identifiable wireless data unit for locating the corresponding wireless client device between two or more of the wireless APs; and determining a location of at least one of the wireless client devices based on reception of at least the corresponding wireless data unit between the one wireless client device and the two or more wireless APs during the corresponding location service interval.

Abstract: Management of radio resources of a wireless network according to a Flexible Radio Assignment (FRA) mode may be provided. For each Access Point (AP) of the wireless network: a type of AP may be identified including determining whether each AP has Multi-Link (ML) capability, and when the FRA mode is for performance, a bias may be applied to each ML capable AP to reduce a likelihood of a radio of each ML capable AP being identified as a redundant radio. For each Client Device (CD) of the wireless network, an identification of whether each CD has ML capability may be made, and a radio configuration of at least one ML capable AP may be tailored to support one or more ML capable CDs.

Abstract: According to one or more embodiments of the disclosure, a device receives data regarding wireless communications between a wireless access point and a client. The device evaluates, based on the data, motion of the client relative to the wireless access point. The device makes, based on the motion of the client relative to the wireless access point, a determination that the motion of the client relative to the wireless access point will result in the wireless communications degrading as the client approaches the wireless access point. The device adjusts the wireless communications, based on the determination that the motion of the client relative to the wireless access point will result in the wireless communications degrading as the client approaches the wireless access point.

Abstract: Systems and methods herein can analyze a bandwidth restriction in a communication stream of an Access Point (AP). Then, based on the bandwidth restriction, the AP can determine a lower amount of wireless bandwidth to provide to station wireless communicating to the AP. The AP can then modify a bandwidth allocation assigned to the station based on the lower amount of wireless bandwidth.

Abstract: A wireless access point device is full-duplex capable and serves wireless communication for at least first and second wireless client devices. The wireless access point device sends to the first wireless client device a trigger frame that causes the first wireless client device to send an uplink transmission to the wireless access point after a first time interval. The wireless access point device waits a second time interval after the first wireless client is expected to begin sending the uplink transmission. The wireless access point device receives the uplink transmission from the first wireless client device. After the second time interval, and while receiving the uplink transmission from the first wireless client device, the wireless access point device sends to the second wireless client device a downlink transmission that overlaps at least partially in frequency and time with the uplink transmission from the first wireless client device.

Abstract: In one embodiment, a first wireless access point (AP) of a first basic service set (BSS) receives, from a second wireless AP of a second BSS, data indicative of an 802.11-based target wake time (TWT) schedule of a client of the second BSS. The first wireless AP identifies, from the receive data, a scheduled communication time of the client of the second BSS in the TWT schedule. The first wireless AP generates an 802.11-based TWT schedule for a client of the first BSS that avoids the scheduled communication time of the client of the second BSS. The first wireless AP sends the generated 802.11-based TWT schedule to the client of the first BSS, wherein the sent TWT schedule causes the client of the first BSS to wake from sleep at a scheduled wake time.

Abstract: An access point allocates resource units within a first channel to mitigate interference from an adjacent second channel. The access point obtains a measure of signal strength corresponding to each wireless device attached to an access point, and assigns, for each wireless device, resource units with a first frequency band of the first channel to mitigate interference with a second frequency band of a second channel adjacent to the first channel. An assignment between a set of resource units and a particular wireless device is based on the measure of signal strength corresponding to the particular wireless device. The access point communicates with the wireless devices on the resource units.

Abstract: Techniques for a machine learning event-driven radio resource management (ED-RRM) module which provides analysis of interference events in a network system are described. The network system reacts to the detection of interference in a network system and uses multiple input parameters to determine a type of device creating the interference, a predicted duration of the interference, and an ED-RRM decision on whether to activate the radio resource management (RRM) processes to alter the network transmission or block the RRM processes to conserve system resources for the network system.

Abstract: In one embodiment, a device in a wireless network receives a target wake time (TWT) request from a wireless client. The device computes TWT parameters based on the received request. The device predicts, using the computed TWT parameters as input to a machine learning model, whether the computed TWT parameters will be accepted by the wireless client. The device provides the computed TWT parameters to the wireless client, based on a prediction by the machine learning model that the client will accept the computed TWT parameters.
