Patent ID: 7359351

Claim:
A method of selecting a channel for wireless audio/visual (A/V) equipment, comprising: establishing a monitoring channel set, the monitoring channel set including at least one channel operable by the A/V equipment; establishing an operation mode as a station mode; scanning each channel of the monitoring channel set to obtain information; computing a parameter based upon the obtained information for each channel; selecting a channel with optimized condition from operable channels by comparing parameters of each channel; and forming a wireless network using the selected channel by converting the operation mode to an Access Point (AP) modes, wherein the parameter computed by the AV equipment is computed for the at least one operable channel, wherein the parameter includes at least one of a parameter distance, which is a distance on a frequency between the computed channel and an interference channel nearest the computed channel; a parameter numBSS_adj, which is a number of external wireless networks within an adjacent channel scope having influence on the computed channel; a parameter numBSS_adj_legacy, which is a number of external wireless networks of a legacy standard within an adjacent channel scope having influence on the computed channel; a parameter interferers_loc, which is a position of an interference channel relative to the computed channel; a parameter numBSS_nearest, which is a number of external wireless networks located at an interference channel nearest to the computed channel; a parameter maxRSSI_nearest, which is a maximum value of signal strengths detected by a channel computed by the external wireless networks; and a first center frequency which is a center frequency of a channel to be computed.
