A device for real-time visualization of the spatial arrival of sub-THz radio waves was successfully realized by combining an 896-element super multi-element antenna developed by NTT and a receiving signal analyzer developed by Keysight Technologies.
Also, combining a SISO channel sounder developed mainly by DOCOMO and a signal transceiver built by Keysight Technologies enabled ultra-high-resolution observation of the temporal arrival of sub-THz signals. Using this equipment, DOCOMO and NTT have successfully conducted radio propagation experiments for ultra-broadband communications in the sub-THz band.
Channel models with dynamic tracking capabilities in real-world environments will be further developed for the design of an efficient ultra-wideband 6G communication system.
