Abstract: In an example embodiment, a method for determining backhaul channel assignments for multi-channel dual radio mesh nodes. The method comprises acquiring collision domain data for each access point of an associated mesh network. A cost function is calculated for each access point of the associated mesh network, the cost function assigning a weighted value for each access point in a collision domain based on a number of access points in the collision domain. Backhaul channel assignments for selected for each access point that minimizes the cost function.
