Abstract
Techniques for enhancing throughput capacity and/or bandwidth distribution fairness among APs in a wireless network are described. Specifically, a channel frequency profile which includes a center frequency and channel-width (i.e., channel bandwidth) is dynamically assigned to each of one or more APs in a wireless network. The assigned channel frequency profile for each AP is based, at least in part, on the current composition of the wireless network including, its topology and traffic load distribution. In this regard, each AP's channel frequency profile can be continuously or periodically changed such that the entire available frequency spectrum is effectively utilized and/or interference between APs is avoided or limited. This, in turn, enhances the throughput capacity and/or bandwidth distribution fairness of the wireless network.
