发明名称 WIRELESS COMMUNICATION SYSTEM, AND WIRELESS COMMUNICATION APPARATUS
摘要 <P>PROBLEM TO BE SOLVED: To provide a wireless communication system and a wireless communication apparatus, capable of shortening time duration adjusting the beam direction to attain proper wireless transmission, even if wireless transmission is performed between devices installed indoors and the like. <P>SOLUTION: The wireless communication system includes a first wireless communication apparatus and a second wireless communication apparatus. The first wireless communication apparatus includes a first antenna, a first evaluator, a first memory, and a first controller. The first antenna can control a beam to a plurality of directions. The first evaluator evaluates the line quality of wireless lines using wireless waves transmitted from the second wireless communication apparatus. The first memory stores a beam pattern information including information indicative of priority for a plurality of beam directions based on the line quality evaluated by the first evaluator. The first controller controls the first antenna, the first evaluator, and the first memory. Then, the first controller controls the beam direction of the first antenna, based on the beam pattern information stored in the first memory. <P>COPYRIGHT: (C)2010,JPO&INPIT
