Method and apparatus of performing direction search and wireless communication by using multiple wireless channel in wireless communication system

The present invention relates to a method and an apparatus of performing direction search and wireless communications by using multiple wireless channels, which is multiple frequency bands, in a wireless communications system, configured to use a plurality of directional antennas facing in different directions, to assign sequentially along the direction one by one in the frequency bands which are predetermined to the directional antennas, to compare the strength of signals received by the directional antennas, and to perform direction search and wireless communications of radio signals through the directional antenna having the most high strength of the received signal by comparing the strength of the received signals of the directional antenna. Therefore, the present invention can provide a frequency diversity effect in an environment where the received signal is severely changed by distance according to the frequency band by the interference of sea reflected wave such as sea.
