<p>PROBLEM TO BE SOLVED: To provide a radio communications system capable of increasing probability of re-connection even if a connection is disconnected due to change of peripheral propagation environment.SOLUTION: A radio communication system includes a transmitter, a receiver, and an antenna device connected to one or both of the transmitter and the receiver. The receiver includes an error detection part for detecting an error of a signal transmitted by the transmitter, and a reception result transmission part for transmitting a result of detection by the error detection part to the transmitter. The transmitter includes a signal transmission part for transmitting a signal, and a signal re-transmission part for re-transmitting a signal transmitted by the signal transmission part on the basis of a result transmitted from the reception result transmission part. The antenna device includes an antenna element for transmitting and receiving a signal, a rotation part for rotating the antenna element, and a rotation amount control part for controlling the amount of rotation of the rotation part on the basis of either of a preset parameter, a parameter transmitted by the transmitter, or a result detected by the error detection part.</p> |
