Abstract: Optimal determination of transmit power level for MLDs in A Wireless Local Area Network (WLAN). An AP can establish synchronous downlink multi-link operations with another MLD. A first link and a second link between the AP and the MLD both operate in a same sub-band. The AP can then determine the same power level for both the first link and second link. After establishing the same power level, the AP can then determine a second power level for the first link and a third power level for the second link. The second power level is greater than the third power level. The AP can then provide the second power level for the first link and the third power level for the second link.

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: Improved Radio Frequency (RF) performance by optimizing temperature may be provided. A plurality of heatmaps may be created associating a plurality of component heat characteristics, of a plurality of components of a device, with a plurality of pre-defined performance trade-off states. Next, a shortest path through the plurality of pre-defined performance trade-off states may be determined. The device may then be placed in successive ones of the plurality of pre-defined performance trade-off states according to the determined shortest path until a Transmit (TX) performance target is met.

Abstract: Optimal determination of wireless antenna configurations may be provided. A computing device may direct an antenna array of an Access Point (AP) to generate a wide beamwidth, to locate a cluster of two or more stations. Upon locating the cluster, the AP can narrow the beamwidth, and, with the narrower beamwidth, receive a key performance indicator (KPI) from at least one of the two or more stations in the cluster. The computing device may then generate a statistical model, based on the KPI and an antenna vector of the antenna array. Based on the statistical model, the computing device can determine a second antenna vector to optimize the KPI for one or more of the client stations. The computing device can then modify the antenna state of the AP to generate the determined antenna vector.

Abstract: Automatically changing Access Point (AP) system configurations for Power over Ethernet (PoE) adaptation and Radio Frequency (RF) power improvement on band edge channels, particularly for Wireless Local Area Networks (WLAN) may be provided. A PoE budget for an AP may be determined. Then, an evaluation of inputs associated with the AP may be performed. The evaluation may include determining an entity input from an entity associated with the AP, determining a client input from a client interfacing with the AP, and/or determining a device input from the AP. Next, a configuration of the AP may be determined based on the PoE budget and the entity input, the client input, and/or the device input. The operation of the AP may be altered based on the configuration.
