HAPS inter-communication and large-capacity multi-cell HAPS building 3D network of 5th generation communication

摘要

In the fifth generation mobile communication or the like, the propagation delay of the wireless communication with the terminal device including the IoT-only device is low, and it is possible to simultaneously connect with a large number of terminal devices, enable high-speed communication, and have a system capacity per unit area. Provides a robust communication system capable of stably constructing a large three-dimensional network over a wide area. The communication system includes a plurality of radio relay stations that relay radio communication between the terrestrial base station and the terminal device. The plurality of wireless relay stations may be installed in a float controlled by the autonomous control or externally controlled to be located in a floating airspace having an altitude of 100 [km] or less and the plurality of first wireless relay stations capable of communicating with each other and having an altitude of 100 [km] or less. And a second radio relay station installed in the floating body on the ground or the sea so as to be located in the floating airspace, and relaying communication between the plurality of first radio relay stations and the ground base station.
