This achievement achieved on September 7 at the Fraunhofer Heinrich Hertz Institute (HHI) in Berlin is a significant step towards the commercialization of 6G THz in open and closed urban areas, since the reference coverage of base stations for urban macrocells is about 250 meters outdoors. That’s a big leap even compared to August 2021, when LG proved it could transmit 6G THz data at a distance of 100 meters outdoors.
6G, which uses ultra-wideband frequencies, has a relatively short range, and power loss from transmission to reception is possible. To solve these problems, LG, the Fraunhofer Heinrich Hertz Institute and the Fraunhofer Institute for Applied Solid State Physics (IAF) jointly developed an amplifier that can increase the transmission power and a low-noise receiver amplifier that improves the quality of incoming signal.
The multi-channel amplifier used in the demonstration has an output greater than 20dBm, which represents an increase of over 5dBm compared to the solutions that LG, HHI and IAF installed in the previous test. A receiver amplifier was also used, which minimizes the generation of noise in the receiving signal. These new technologies are integrated into LG’s latest modular design ready for future integrated circuit manufacturing to ease the path to commercialization.
“With this latest success, we are one step closer to realizing 6G speeds of 1 terabit per second in open and closed urban areas,” said Dr. Kim Byoung-hoon, CTO and Executive Vice President of LG Electronics. “LG will continue to work with research institutes and innovators to further solidify leadership in 6G technology. We expect 6G to be the main driver of future business and new user experiences, so there’s no place we’d rather be than here, at the forefront of its development.”
LG plans to announce the full results of its latest 6G communications test and an overview of the technology’s development so far at the upcoming 6G Grand Summit to be held on September 23 at the LG Science Park in Seoul. The company is hosting the event in collaboration with the Korea Advanced Institute of Science and Technology (KAIST) and the Korea Research Institute of Standards and Science (KRISS).
Discussions on 6G network standardization are expected to begin around 2025, and commercialization of the technology is expected in 2029. Compared to 5G wireless networks, 6G will provide far better data rates with lower latency and higher reliability.
Global companies are racing to enter the 6G space given the key role it will play in enabling all kinds of innovation, from ultra-realistic mobile holograms to the next phase of the Internet of Things and ambient computing, which will provide a more flexible and personal experience through organically connecting people, objects and space.
To ensure its continued leadership in 6G, LG actively collaborates with renowned research institutes, universities and companies from around the world. The company also aims to establish core 6G R&D collaborations with organizations including HHI, IAF, KAIST, KRISS and Keysight Technologies, Inc. to accelerate the arrival of the next generation of wireless network communications.
Also, the Next Generation Alliance (Next G Alliance), an initiative of the Alliance for Telecommunications Industry Solutions (ATIS – Alliance for Telecommunications Industry Solutions), chose LG in June 2021 as the leader of the working group for applications that will discuss 6G technologies and lead the future direction of 6G telecommunications services.
