To provide a communication system in which propagation delay of radio communication is low between the system and terminals including a device for IoT in the fifth generation communication or the like, the system can simultaneously connect to a plurality of terminals in a wide range, high speed communication is possible, and the system is excellent in robustness where three dimension network with a large system capacity per unit area can be stably constructed over a wide area.SOLUTION: A communication system includes a plurality of radio relay stations relaying radio communication between a ground base station and a terminal. The radio relay stations comprises: a plurality of first radio relay stations installed in a floating body controlled to be positioned at levitation space altitude of which is 100 Km or less by autonomous control or external control and capable of communicating to each other; and a second radio relay station installed in a floating body moored on the ground or on the sea to be positioned at a levitation space altitude of which is 100 Km or less and relays radio communication between the first radio relay stations and the ground base station.SELECTED DRAWING: Figure 1

    【課題】第5世代移動通信等においてIoT向けデバイスを含む端末装置との間の無線通信の伝搬遅延が低く、広範囲の多数の端末装置と同時接続でき、高速通信可能で、単位面積あたりのシステム容量の大きい3次元化したネットワークを広域にわたって安定に構築できるロバスト性に優れた通信システムを提供する。【解決手段】地上基地局と端末装置との無線通信を中継する複数の無線中継局を備える通信システムであって、複数の無線中継局は、自律制御又は外部から制御により高度が100[km]以下の浮揚空域に位置するように制御される浮揚体に設けられ相互に通信可能な複数の第1無線中継局と、高度が100[km]以下の浮揚空域に位置するように地上又は海上に係留された浮揚体に設けられ複数の第1無線中継局と地上基地局との通信を中継する第2無線中継局とを含む。【選択図】図1
