Abstract: Techniques for dynamic bandwidth expansion are provided. A first set of channel quality metrics is collected, by an access point (AP) communicating using a first bandwidth, for an expanded bandwidth beyond the first bandwidth. A second set of channel quality metrics for the expanded bandwidth is received from one or more stations. An available portion of the expanded bandwidth is then determined based on the first and second sets of channel quality metrics. Communication with the one or more stations is initiated using the available portion of the expanded bandwidth.

Abstract: A method to manage access points in a wireless network to save power during off-peak hours. The method includes operating a wireless local area network including access points with the access points powered on, receiving information indicative of channel utilization levels for each of the access points over a predetermined period of time, receiving respective indications of occupancy levels of a space that is covered by the access points during the predetermined period of time, predicting a low occupancy period of the space based on the channel utilization levels and the respective indications of occupancy levels, and during the low occupancy period, causing a first group of the access points to be powered off, and causing a second group of the access points to remain powered on.

Abstract: Techniques for assigning APs to wireless network controllers are described. One or more RF constellations for a plurality of APs in a wireless network are generated. The RF constellations are organized based on estimated RF distances among the plurality of APs. The plurality of APs are clustered into a plurality of groups of one or more APs, based on the RF constellations and the estimated RF distances. Each group, of the plurality of groups, is assigned to a wireless network controller.
