Abstract

A wireless communication system includes a first communication apparatus that moves, a second communication apparatus that moves, and a reception apparatus. A first control unit of the first communication apparatus, when an own apparatus can communicate with any of the reception apparatuses, transmits transmission data acquired by the own apparatus from a first communication unit to the reception apparatus, and, when the own apparatus cannot communicate with any of the reception apparatuses, transmits the transmission data from a second communication unit to the second communication apparatus capable of communicating with the own apparatus. A second control unit of the second communication apparatus transmits the transmission data received by a third communication unit from the first communication apparatus from a fourth communication unit to a reception apparatus capable of communicating with the own apparatus.

Claims15

Dependent claims

A wireless communication system comprising one or more first communication apparatuses that move, one or more second communication apparatuses that move, and one or more reception apparatuses, wherein

a first communication apparatus included in the one or more first communication apparatuses includes
a first transceiver that wirelessly communicates with at least one of the reception apparatuses,
a second transceiver that wirelessly communicates with at least one of the second communication apparatuses, and
a first controller that, when the first communication apparatus can communicate with any of the reception apparatuses, transmits transmission data acquired by the first communication apparatus from the first transceiver to one of the reception apparatuses capable of communicating with the first communication apparatus, and, when the first communication apparatus cannot communicate with any of the reception apparatuses, transmits the transmission data from the second transceiver to one of the second communication apparatuses capable of communicating with the first communication apparatus, and
a second communication apparatus included in the one or more second communication apparatuses includes
a third transceiver that wirelessly communicates with at least one of the first communication apparatuses,
a fourth transceiver that wirelessly communicates with at least one of the reception apparatuses, and
a second controller that transmits the transmission data received by the third transceiver from one of the first communication apparatuses from the fourth transceiver to one of the reception apparatuses capable of communicating with the second communication apparatus.
