Inter-HAPS communication and high-capacity multi-cell HAPS to build a 3D network of 5th generation communication

摘要

In the fifth generation mobile communication, etc., the overall delay of wireless communication between a terminal device including an IoT-only device is low, it is possible to simultaneously connect to a large number of terminal devices, high-speed communication is possible, and the system capacity per unit area is reduced. Provided is a communication system excellent in robustness that can stably construct a large three-dimensional network over a wide area. The communication system includes a plurality of radio relay stations that relay radio communication between a terrestrial base station and a terminal device. The plurality of wireless relay stations is installed in a floating body controlled to be located in a floating airspace having an altitude of 100 [km] or less by autonomous control or external control, and the plurality of first wireless relay stations and altitudes of 100 [km] And a second wireless relay station installed on a floating or moored floating body so as to be located in the following floating airspace and relaying communication between a plurality of first wireless relay stations and a terrestrial base station.
