Abstract
A method includes receiving at a gateway mesh node a channel set list indicating radio channels that are allowed for use by the gateway mesh node, scanning channels in the channel set list and creating a list of channels in order of interference that is present, allocating channels from the list of channels to a plurality of radios that comprise the gateway mesh node, and initiating transmission of beacon frames from each of the plurality of radios on a main channel. Each beacon frame includes information descriptive of a path cost representing a sum of all link costs back to a central point, a primary radio channel used by the radio transmitting the beacon frame, a channel set indicating only those channels that an associated portion of the mesh network is allowed to use, and a set of meshed nodes associated with the radio.
