In the next generation communication systems such as Beyond-5G/6G, non-terrestrial networks (NTN) are attracting attention as they expand communication networks globally and three-dimensionally to sea, air, and space. Activities toward introducing NTN are progressing both in Japan and overseas, and radio technologies, digitization technologies, optical technologies, and network technologies are the keys to applying NTN by solving problems caused by performance differences with terrestrial networks. NTN are also expected to flexibly respond to the resolution of global social issues such as SDGs. |
