Achieving the World’s Highest Wireless Transmission Rate by Delving into Theories That Appeared about 100 Years Ago
Doohwan Lee · NTT technical review · 2024
With the advent of smartphones, mobile communications have rapidly become popular.Fifth-generation mobile communications system (5G) services, which feature high speed, large capacity, low latency, and simultaneous connection to multiple terminals, are spreading, and the 3rd Generation Partnership Project (3GPP), an international standardization organization, has begun initial discussions on 6G.The technological foundation for the advancement of mobile communications is wireless transmission technology.Doohwan Lee, a senior distinguished researcher at NTT Network Innovation Laboratories, and his colleagues achieved the world's first high-capacity wireless transmission of 1.44 Tbit/s using the sub-terahertz band.We interviewed him about the technology that enabled this achievement, his research themes aiming at exploiting all the properties of radio waves, and his thoughts on the importance of researcher well-being for enabling them to make people happy through research.
