초록 ▼

A communication apparatus transmits a test message in one direction by the transmitting unit having narrow directivity capable of changing the transmitting direction, and an indication message which indicates that the test message is being transmitted by a transmitting unit having non directivity. Accordingly, the indication message is transmitted at least to the communicating party\s apparatus. Subsequently, the transmitting direction of the test message is sequentially changed, and a similar process is performed. When the communicating party\s apparatus detects a reception of the indication message, information indicating a level of the test message is transmitted to the transmitting apparatus as a response. The communication apparatus at the transmitting side detects the direction where the communicating party exists by receiving the information indicating the level. Hereinafter, the information communication is performed to adjust the transmitting unit of narrow directivity to the determined direction.

대표청구항 ▼

A communication apparatus which performs an information communication by using wave motion in space propagation, comprising: first transmission means for transmitting information at a first speed with a first directivity; changing means for successively changing a transmission direction of the information to be transmitted by said first transmission means; second transmission means for transmitting information at a second speed lower than the first speed with a second directivity wider than the first directivity; reception means for receiving information transmitted from a communicating party of said communication apparatus; testing means for performing a plurality of testing processes, each of which transmits a first message in a predetermined direction by said first transmission means, and a second message indicating that the first message is being transmitted by said second transmission means whenever the transmission direction of the first message to be transmitted by said first transmission means is changed by said changing means; and selection means for selecting one of the transmission directions of the first message to be transmitted by said first transmission means in accordance with a third message transmitted from the communicating party, in response to the second message transmitted in each of the testing processes performed by said testing means.
