An information channel and power combined self-configuration method for APs (Access Points) in
wireless local area network comprises the steps as follows: the area where the APs to be configured are located is selected as a local network, and the local network is divided into a plurality of grids according to practical conditions; each AP sends out a self-configuration request to a
server and simultaneously reports the position coordinate of the AP and the scanned
frequency spectrum use information of the ambient environment of the AP; the
server analyzes the positions and the ambient environments of the APs according to the self-configuration requests of the APs, and allocates information channels and power parameters to the APs to be configured in combination with the use conditions of AP information channels in neighbor cells under the premises of meeting the coverage rate requirement and minimizing same frequency interference, that is, first the
signal energy of each grid is estimated according to a
path loss empirical model to learn the network coverage condition, and then the information channel and the
power parameter eventually configured for each AP is obtained through calculation based on the principle that the energy efficiency ratio is highest, and are sent to the AP to be configured. The method provided by the invention is quick and effective, guarantees the region coverage requirement, avoids same frequency interference to the maximum extent and guarantees that the energy efficiency ratio of the network is highest.
