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.

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 the at least one of the reception apparatuses, transmits transmission data acquired by the first communication apparatus, using the first transceiver, to the at least one of the reception apparatuses capable of communicating with the first communication apparatus,
wherein the first controller when the first communication apparatus cannot communicate with the at least one of the reception apparatuses, transmits the transmission data, using the second transceiver to the at least one of the second communication apparatuses capable of communicating with the first communication apparatus, and
wherein a second communication apparatus included in the at least one of the one or more second communication apparatuses includes:
a third transceiver that wirelessly communicates with the first communication apparatus;
a fourth transceiver that wirelessly communicates with the at least one of the reception apparatuses;
and
a second controller that transmits the transmission data received by the third transceiver from the first communication apparatus, using the fourth transceiver, to the at least one of the reception apparatuses capable of communicating with the second communication apparatus,
wherein the first controller, when the first communication apparatus cannot communicate with the at least one of the reception apparatuses and the acquired transmission data has a high priority, transmits the transmission data, using the second transceiver, to the at least one of the second communication apparatuses capable of communicating with the first communication apparatus, and
wherein the first controller, when the first communication apparatus cannot communicate with the at least one of the reception apparatuses and the acquired transmission data does not have the high priority, transmits, after the first communication apparatus becomes capable of communicating with the at least one of the reception apparatuses, the transmission data, using the first transceiver, to the at least one of the reception apparatuses capable of communicating with the first communication apparatus.

7 more elements

A wireless communication method of communication apparatuses in a wireless communication system including;

a first communication apparatus that moves;
a second communication apparatus that moves;
and one or more reception apparatuses, the wireless communication method comprising:
transmitting, by the first communication apparatus, when the first communication apparatus can communicate with at least one of the reception apparatuses, transmission data acquired by the first communication apparatus, using a first transceiver that wirelessly communicates with the at least one of the reception apparatuses, to the at least one of the reception apparatuses capable of communicating with the first communication apparatus, and
transmitting, by the first communication apparatus, when the first communication apparatus cannot communicate with the at least one of the reception apparatuses, the transmission data, using a second transceiver that wirelessly communicates with the second communication apparatus, to the second communication apparatus that capable of communicating with the first communication apparatus and the at least one of the reception apparatuses,
wherein a controller of the first communication apparatus, when the first communication apparatus cannot communicate with the at least one of the reception apparatuses and the acquired transmission data has a high priority, transmits the transmission data, using the second transceiver, to the second communication apparatus capable of communicating with the first communication apparatus, and
wherein the controller of the first communication apparatus, when the first communication apparatus cannot communicate with the at least one of the reception apparatuses and the acquired transmission data does not have the high priority, transmits, after the first communication apparatus becomes capable of communicating with the at least one of the reception apparatuses, the transmission data, using the first transceiver, to the at least one of the reception apparatuses capable of communicating with the first communication apparatus.
