Abstract (in Japanese) (See Japanese page) 
(in English) High-Speed and broadband network transformation is needed for multi-points collecting sensing data and distributing moving data in cyber-physical systems. Ultra-high speed and capacity is one of key factors for 6 G. Futhermore, a target example of wireless transmission rate is more than 100 Gbit/s. In order to realize 100Gbit/s for wireless access network, we focus on distributed antenna systems using high-frequency-band such as millimeter wave and terahertz-bands with bandwidth of more than 1GHz. This report describes its system concept and evaluates theoretical system capacity. Moreover, it describes technical problems of this systems and introduces A-RoF (Analog Radio over Fiber) system, positioning sensing, and user selection for multi-user transmission to solve these problems.
