Abstract:
1. A channel-searching method used in a wireless network having a first wireless network service provider and at least one second wireless network service provider, comprising the steps of: providing the first wireless network service provider with both a signal-strength information and a channel-influence information resulting from each of the at least one second wireless network service provider; generating an interference information based on the signal-strength information and the channel-influence information from the at least one second wireless network service provider by the first wireless network service provider; and selecting an optimum channel as an operating channel for the first wireless network service provider according to the interference information, wherein the channel-influence information is the influence ratio representing the influence of the at least one second wireless network provider upon each channel, the influence ratio being determined by the formula: influence ratio=(22−5×N)/22, where N represents the difference between the channel numbers of any two channels.
