Korean Research Team Succeeds in World's First 200 Gbps Wireless Communication for 6G Mobile Communications

The Electronics and Telecommunications Research Institute of Korea (ETRI) announced on January 23, 2025, that it has developed a proof-of-concept (PoC) system for 6G mobile communications and successfully demonstrated the world's first 200 Gbps wireless link.

According to the announcement, ETRI's research team demonstrated a multipoint transmitter/receiver technology that transmits data using a bandwidth of 10 GHz in the sub-THz band at the end of 2024. Using four base station radio units (RUs) that simultaneously transmit signals in the same frequency band and advanced beamforming technology that minimizes signal interference, the team achieved a total transmission rate of over 200 Gbps.

To make this demonstration a success, ETRI implemented innovative signal transmission and reception techniques, advanced interference reduction techniques, and coding and decoding technologies that make large data channels manageable. This successfully increased data throughput by a factor of four, demonstrating the potential of the sub-THz band for short-range, high-capacity applications such as indoor picocells and high-resolution sensing.

ETRI emphasized that this achievement "was made possible through collaborative efforts with domestic partners (Samsung, CleverLogic, SnetICT, Komotech, etc.) and years of basic research. Baek Yong-soon, head of the research institute's 3D Communications Laboratory, also commented, "We will continue to do our best to lead the world's 6G standardization and industrialization.
