Abstract:
1. An access point for a wireless communication network, comprising a processor and memory storing data and instructions, arranged to dynamically select an optimum channel by carrying out the following steps: (a) selecting a channel from a plurality of possible channels; (b) collecting data as to at least level of Medium Activity on said channel during a predetermined scanning time; (c) storing a channel interference parameter indicative of a time period in said scanning time that said level of Medium Activity exceeded a first threshold value; (d) repeating steps (b) and (c) for all other channels of said plurality of channels; (e) selecting said optimum channel in accordance with a predetermined rule taking said channel interference parameter into account, and wherein said channel interference parameter, at system startup, is defined as CI(j)=T_interference(j)/T_scan(j) with T_scan(j) being said scanning time on said channel (j) and T_interference(j) being a time period in said scanning time that said level of activity exceeded said first threshold.
