Document Type and Number:
Japanese Patent JP6877152
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a technology of an unmanned aircraft, in which the throughput of cellular communication is less likely to decrease.SOLUTION: An unmanned aircraft includes: three or more antennas 24 which are different from each other in the directivity direction; and a cellular communication part 11 for performing cellular communication using an antenna having smaller influence of an interference wave as compared with other antennas out of three or more antennas 24. A part of an airframe of the unmanned aircraft is used as three or more antennas 24. The cellular communication is performed using the antenna having smaller influence of the interference wave as compared with the other antennas out of three or more antennas 24, thereby the throughput of cellular communication is less likely to decrease.SELECTED DRAWING: Figure 1
