COMMUNICATION SYSTEM UNDERSTANDING A PLURALITY OF RADIO RETRANSMISSION STATIONS TO RETRANSMIT A RADIOCOMMUNICATION WITH A TERMINAL DEVICE AND REMOTE CONTROL DEVICE

摘要

a highly robust communication system capable of stably creating a three-dimensional network over a wide area can be provided, in which a propagation delay is low, a simultaneous connection to a large number of terminals in a wide area and high-speed communication speed can be performed, and a system capacity per unit area is large, in radio communications with terminal devices including iot devices, in fifth generation mobile communications or the like. the communication system comprises a plurality of radio relay to relay radio communication between a terrestrial base station and a terminal device. the plurality of radio relay stations include a plurality of first radio relay stations capable of communicating with each other, each first radio relay station being provided in a floating controlled object to be located in a floating air space with a altitude less than or equal to 100 km by an autonomous control or an external control, and a second radio relay station to relay a communication between the plurality of first radio relay stations and the terrestrial base station, the second relay station radio being provided in a floating object anchored on the ground or in the sea, in order to be located in a floating airspace with an altitude less than or equal to 100 km.
