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: Noise floor degradation detection may be provided. First, an incremental packet loss rate for a secondary radio may be calculated that indicates an impact on packet reception on the secondary radio due to transmissions by a primary radio. The secondary radio and the primary radio may comprise an access point. Next, it may be determined that the incremental packet loss rate is greater than a predetermined value. A configuration of the access point may be changed in response to determining that the incremental packet loss rate is greater than the predetermined value.

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: In one embodiment, a method is performed. A device may receive an antenna state configuration and a sequence from a wireless access point (AP) device. A plurality of antenna states configured on the device may be selected based on the antenna state configuration and the sequence. An inertial measurement unit (IMU) measurement may be determined. A beacon signal may be transmitted for each selected antenna state. Each transmitted beacon signal may indicate a corresponding selected antenna state.

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.
