[Press Release]Development of Sub-THz Wideband Mobile Transmission Testbed for 6G and Successful Basic Transmission of Vehicle-Oriented Communication Systems

A research group led by Professor Hiroshi Harada and Assistant Professor Yusuke Koda at the Graduate School of Informatics, Kyoto University, has developed a wideband mobile transmission testbed using software-defined radio technology in the sub-terahertz band (100 GHz) for future 6G systems. In field trials conducted on a roadway approximately 200 meters long from an intersection, the group successfully achieved wideband mobile transmission with a channel bandwidth of 920 MHz—more than twice the maximum 5G channel bandwidth in Japan (400 MHz)—while adhering to the 5G-standardized transmission formats with the data rate of 1.7 Gbit/s. This achievement is expected to accelerate research and development for building ultra-high-speed wireless communication infrastructure capable of rapidly transmitting vehicle-related perception data, such as stationary camera footage at intersections, thereby contributing to a safer traffic society.
