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.
