  • Techniques to create, update, disseminate, and use dynamic subset backhaul channel lists in a mesh network
    Patent number: 9521608
    Abstract: A mesh network includes a controller, root access points (APs), and mesh APs assigned to different groups of APs. The controller creates for each group a distinct subset channel list of backhaul channels used by root APs of the group that are connected to the controller. The controller updates, for each group, the subset channel list as root APs assigned to the group connect with and disconnect from the controller. The controller sends, for each group, the subset channel list to the mesh APs assigned to the group that are connected with the controller through respective root APs when the subset channel list is created and updated.
