  • Automatic channel selection in wireless local area network (WLAN) controller based deployments
    Patent number: 9992737
    Abstract: Wi-Fi channels are automatically selected in a WLAN controller based deployment. Scan results received from each of the plurality of access points comprise a list of neighboring access points from the plurality of access points relative to each access point. Responsive to a number of the plurality of access points exceeding a number of non-interfering channels, assigning each of the plurality of access points to a non-interfering channel with sharing of at least one of the non-interfering channels, using a GCA (Graph Coloring Algorithm) in which each color assignment corresponds to a non-interfering channel assignment in order to prevent neighboring access points from sharing a non-interfering channel. Lowest RSSI measurements collected by access points can also be a factor in channel selection.
    Type: Grant
