Centralized wifi channel selection

An apparatus configured to perform dynamic channel selection, comprising:

• means for receiving, at a central self-organizing network server, data from an access point (AP) including a number of stations associated with the AP;
• means for calculating downlink capacities for the associated stations;
• means for selecting a channel for the AP which maximizes a pre-defined network utility that is based on the downlink capacities;
• means for determining if the network utility gain resulting from selecting the channel exceeds a threshold when compared to a previous channel selection state;
• and
• means for issuing, if the network utility gain exceeds the threshold, a channel change command to the AP directing the AP to use the selected channel to communicate with a specific station.

An apparatus configured to perform dynamic channel selection, comprising:

• a processor;
• and
• a memory coupled to the processor and storing instructions configured to cause the processor to:
• receive, at a central self-organizing network server, data from an access point (AP) including a number of stations associated with the AP;
• calculate downlink capacities for the associated stations;
• select a channel for the AP which maximizes a pre-defined network utility that is based on the downlink capacities;
• determine if the network utility gain resulting from selecting the channel exceeds a threshold when compared to a previous channel selection state;
• and
• issue, if the network utility gain exceeds the threshold, a channel change command to the AP directing the AP to use the selected channel to communicate with a specific station.
