  • Patent number: 10327186
    Abstract: A technique for providing per station control of multiple stations in a wireless network across multiple access points. A look-up table that assigns a station connected to the access point and at least one communication parameter to each of a plurality of persistent, uniquely-assigned BSSIDs (Basic Service Set Identifiers) is stored. An access point responds to messages addressed one of the plurality of persistent, uniquely-assigned BSSIDs and ignores messages addressed to other BSSIDs. Persistence of the BSSID allows the controller to maintain individual control over each station after moving to a second access point of the plurality of access points. A frame comprising the plurality of BSSIDs corresponding to each connected station aggregated into the frame is generated. The frame is transmitted to the plurality of stations.

  • Patent number: 9210587
    Abstract: Deploying multiple access points on multiple wireless communication channels to optimize coverage area. Additional channels provide additional communication capability which multiple AP's, and their associated stations, can collectively use. An additional set of AP's can be disposed in the additional communication channel, with multiple communication channels possibly physically intersecting. The system control element collects information from devices in the wireless communication system, and automatically configures which AP is assigned to which communication channel. The system control element determines which AP's are servicing which physical locations, in response to feedback from AP's and stations in those locations. The system control element assigns, or re-assigns, AP's in each physical location, with the effect of optimizing coverage.
