LG successfully demos 6G data transmission using terahertz spectrum

Industry 10:00 August 19, 2021

SEOUL, Aug. 19 (Yonhap) -- LG Electronics Inc. on Thursday said it has successfully demonstrated 6G data transmission using the terahertz spectrum as the South Korean tech giant tries to move ahead in the next-generation communication technology.

LG succeeded in sending 6G terahertz wireless communication signals 100 meters in an outdoor environment in collaboration with Fraunhofer-Gesellschaft, Europe's leading application-oriented research organization, in Berlin last week.

LG said it developed a new power amplifier with Fraunhofer-Gesellschaft in order to deliver stable communication signals at the 6G terahertz spectrum.

The ultrawide band spectrum has a short frequency coverage range, while power losses in antenna transmitting and receiving processes are severe, demanding enhanced power amplifiers to solve such problems.

LG said its new amplifier can deliver a maximum output signal of 15 decibel-milliwatts for stable communication in the 155-175 gigahertz band.

LG added it also developed adaptive beamforming and high-gain antenna switching technologies for the 6G terahertz wireless communication demonstration.

LG expects 6G communication to be commercialized in 2029, with talks for standardization beginning in 2025.

The company believes the next-generation telecommunications network can provide faster data speed, lower latency and higher reliability than 5G, and will be able to bring the concept of Ambient Internet of Everything (AIoE), which provides enhanced connected experiences to users.

LG established a 6G research center with KAIST in 2019 and signed an agreement with the Korea Research Institute of Standards and Science last year to study 6G technologies.

In June, the company's principal researcher was elected the chair of the applications working group in the Next G Alliance, a North American mobile technology alliance for 6G solutions development.
