Corrected predictions for wireless LAN with dynamic frequency selection (DFS)

摘要

The present invention describes an algorithm for the selection of channels used by access points (APs) in wireless LANs in a dynamic way in order to achieve the best performance. The selection of channels is based on a procedure in which an AP is scanning its possible channels in order to gather information on interference and channel sharing. A decision for the optimum channel is based on estimated interference and channel sharing, calculated with help of information coming from other APs, and on experienced interference and channel sharing that is calculated using information on foreign activity time of the AP and the amount of retransmitted data by the AP. <IMAGE>
