SEOUL, Aug. 19 (Yonhap) – LG Electronics Inc. on Thursday announced that it has successfully demonstrated 6G data transmission using the terahertz spectrum as the South Korean tech giant attempts to advance in communications technology from new generation.

LG managed to send 6G terahertz wireless communication signals 100 meters away in an outdoor environment in collaboration with Fraunhofer-Gesellschaft, Europe’s leading application-oriented research organization, in Berlin last week.

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

Ultra-wideband spectrum has a short frequency coverage range, while the power losses in the antenna transmit and receive processes are severe, requiring improved power amplifiers to solve such problems.

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

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

LG expects 6G communication to go to market in 2029, with talks for standardization starting in 2025.

The company believes that the next-generation telecommunications network can deliver faster data speed, lower latency, and higher reliability than 5G, and will be able to bring the concept of ambient internet to anything (AIoE ), which provides enhanced connected experiences for users.

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

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