On March 21, 2024, DOHI Yusuke won the 39th Telecom System Technology Award of the Telecommunications Advancement Foundation. In March 2017, after completing the doctoral course, DOHI Yusuke received his doctorate in engineering from Meiji University. Since then, he has been engaged in the research and development of radio communications in the railway business at the Research and Development Center of JR East Group, East Japan Railway Company.
The Telecom System Technology Award is given to individuals and organizations who have made outstanding contributions to telecommunications systems and technology. The winners are evaluated in society and honored for their high levels of achievement in the development, promotion and quality improvement of technologies and systems that have contributed to the development and innovation of communications.
DOHI’s first-authored paper, “Local 5G Verification Test on Shinkansen Deadhead Line and Rolling Stock Center,” which was published in August 2023 in the Japanese Journal B of the Institute of Electronics, Information and Communication Engineers, was evaluated for its high effectiveness and future potential.
This paper contains findings from various measurements: measuring the throughput of the local 5G system between the ground and the inside of a Shinkansen train running on the deadhead line, checking transmitted images in each transport layer protocol, measuring communicable areas considering uplink communication, measuring the propagation characteristics of various radio waves in a Shinkansen train at the leaving depot of the Rolling Stock Center, and measuring the interference control areas. The results of the verification tests reported in this paper are not only expected to contribute to the development of the railway business, but are also expected to promote wider use of the local 5G system in many industries, including railways, identify and solve problems, and help improve the system itself.
