RESEARCH PROJECTS

When 5G is put into practical use, the communication can be realized under such the areas and environments where the terrestrial communications are difficult to be used at present, and it is expected that IoT that the people and every sort of things are connected via the wireless communication and the more advanced IoE are widely disseminated. However, 5G services still remain unavailable over the sea, at the mountains and at the isolated areas, where radio waves cannot reach, or when base stations are damaged due to disasters.

To solve these problems of connectivity, the Space Communication Systems Laboratory has been carrying out the research and development aiming for constructing space-ground integrated networks with a view to use the big date in space by combining optical satellite communications and Ka-band satellite communications to support 5G communications.
