For provide a wireless communication system and a wireless communication
apparatus, for enabling preferable wireless transfer, reducing the time
taken for adjustment of the beam direction, even in the case where the
wireless transfer is conducted between the apparatuses installed within
the room, etc., according to the present invention, there is provided a
wireless communication system comprising a first wireless communication
apparatus and a second wireless communication apparatus. The first
wireless communication apparatus comprises a first antenna, which is able
to control a beam into a plural number of directions, a first estimate
portion, which estimates a network quality of a wireless network with
using a radio wave transmitted from the second wireless communication
apparatus, a first memory portion, which memorizes a beam pattern
information including information indicative of priorities of the plural
number of beam directions upon basis of the network qualities estimated
by the first estimate portion, and a first controller portion, which
controls the first antenna, the first estimate portion and the first
memory portion. And, the first controller portion controls the beam
direction of the first antenna upon basis of the beam pattern information
memorized in the first memory portion.
