LG Electronics Displays 6G Tech In South Korea

South Korean technology company LG Electronics displayed 6G technology during the ‘2021 Korea Science and Technology Exhibition’ recently held at KINTEX in Ilsan, South Korea.

During the event, LG was expected to unveil a power amplifier for 6G for the first time, a device it has cooperatively developed with Germany’s Fraunhofer Research Institute.

This is the same amplifier that was used by LG during its 6G demo in Berlin in August 2021. At that time, LG Electronics said it has effectively manifested the transmission and reception of wireless “6G” terahertz (THz) data over 100 meters in an outdoor setting.

 

6G systems do not practically exist because they have not yet been regularized, but terahertz frequencies — beyond millimeter wave — are being explored to be part of future systems.

 

LG stated that due to terahertz frequencies have a short range and experiences power loss during transmission and reception between antennas, one of the biggest test for the future of wireless 6G is the need for power amplification to create a stable signal across ultra-wideband frequencies.

 

The power amplifier developed by LG, Fraunhofer HHI and Fraunhofer Institute for Applied Solid State Physics (IAF) was crucial to the success of this latest test, the Korean company added.

 

The power amplifier is capable of generating stable signal output up to 15 dBm in the frequency range between 155 to 175 GHz. LG noted that it was also successful in demonstrating adaptive beamforming technology, which alters the signal’s direction in accordance with changes to the channel and receiver position; as well as high-gain antenna switching, which combines output signals of multiple power amplifiers and transmits them to specific antennas.

 

In 2019, LG set up the LG-KAIST 6G Research Center in partnership with the Korea Advanced Institute of Science and Technology (KAIST).

LG and KAIST had previously partnered with U.S.-based test and measurement firm Keysight Technologies with the aim of carrying out research on future 6G technologies.

 

Under the terms of the agreement, the three partners will cooperate in enhancing technologies related to terahertz frequencies, broadly seen a key frequency band for 6G communications, which have not yet been regularized. The partners aim to finish 6G research by 2024.

 

LG initially said that 6G is expected to be popularized in 2029. LG also stated that future 6G technologies will 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 increased connected experience to users.

 

The government of South Korea initially said it aims to announce a pilot project for not-yet-standardized 6G mobile services in 2026. The Korean government expects 6G services could be commercially available in Korea between 2028 and 2030.

 

The Korean government’s strategy for 6G consists of preemptive development of next-generation technologies, obtaining standard and high value-added patents, and laying R&D and industry foundations. The government picked five major areas for the pilot project: Digital healthcare immersive content, self-driving cars, smart cities and smart factories.

 

RCR Wireless News published an editorial report about future 6G technology dubbed “Is it really time to start talking about 6G?”, in which key industry leaders and analysts talk about the previous efforts towards the future growth of 6G.
