Abstract
Client balancing in a wireless digital network comprising a plurality of access nodes connected to a controller. Access nodes collect client density information and periodically report that client density information to the controller. The controller uses the client density information from the access nodes to compute Virtual RF Neighborhoods, identifying Virtual RF neighboring access nodes. Two access nodes are Virtual RF neighbors if a client which can connect to one access node can also connect to the other access node. The controller then identifies which nodes are overloaded by comparing the client loading of a target access node to the client loading of its Virtual RF neighbors. If an access node is identified as overloaded and selected for client balancing on a particular channel, it will initially refuse new association requests from client devices on that channel.
