Abstract: A first wireless communication device includes: a first communication unit; and a first addition unit that adds first additional information to a connection signal. A second wireless communication device includes: a second communication unit; and a second addition unit that adds second additional information that differs from the first additional information to a connection request signal requesting connection with the first wireless communication device. The second communication unit transmits to the first wireless communication device the connection request signal with the second additional information added when the second communication unit receives from the first communication unit the connection signal with the first additional information added. Then, the first communication unit transmits to the second wireless communication device a connection response signal for responding to the connection request signal and receives data from the second wireless communication device when the first communication unit receives from the second communication unit the connection request signal with the second additional information added.

Abstract: An inter-vehicle communication system is a system that provides communication between vehicles with use of a beam having a directivity and includes a first antenna and a second antenna. The first antenna is provided to a first vehicle, and performs wireless communication. The second antenna is provided to a second vehicle coupled to the first vehicle, and performs wireless communication. The second antenna emits a beam toward the first antenna. In a state where the first vehicle and the second vehicle are aligned to each other, a position in a horizontal direction of the first antenna is different from a position in the horizontal direction of the second antenna.

Abstract: A train communication system is configured to perform wireless communication between two cars coupled to each other by using low power radio. The train communication system includes: a first device disposed on one coupling surface of two coupling surfaces facing each other between two cars; a second device disposed on the one coupling surface; a third device disposed on another coupling surface of the two coupling surfaces; and a fourth device disposed on the other coupling surface. The first device and the third device are disposed to face each other. The second device and the fourth device are disposed to face each other. When no wireless connections are established among the first device, the second device, the third device, and the fourth device, the first to fourth devices each perform at least one of switching of communication channels used for wireless communication among the first to fourth devices and switching of a master device or a slave device.

Abstract: A communication system includes a transmission terminal and a reception terminal, and the transmission terminal transmits data to the reception terminal. The transmission terminal includes a storage unit that stores data and management information of the data, and a first communication unit that performs communication using a first radio method having non-directivity and a second radio method having directivity. The reception terminal includes a second communication unit that performs communication using the first radio method having non-directivity and the second radio method having directivity, and a selector that selects the data based on the management information. The first communication unit and the second communication unit communicate with each other using the first radio method having non-directivity when selecting the data to be transmitted, and communicates with each other using the second radio method having directivity when transmitting the selected data.

Abstract: A communication device includes: a distance information acquisition unit configured to acquire distance information indicating a distance to a communication target; a setting information acquisition unit configured to acquire setting information including a communication distance; and a communication unit configured to communicate with the communication target. The distance information acquisition unit acquires the distance information after the communication unit establishes connection with the communication target. The communication unit cuts the connection with the communication target when the distance information does not satisfy the communication distance included in the setting information.
