LG Electronics (LG) has successfully tested the wireless transmission and reception of 6G terahertz (THz) data.
The test was conducted on 7 September at the Fraunhofer Heinrich Hertz Institute (HHI) in Berlin, Germany using a frequency range of 155 to 175 GHz over a distance of 320 meters, outdoors.
In contrast, LG proved it could transfer 6G THz data over a distance of 100 meters outdoors last year in August. The reference cell coverage of base stations for urban macro cells is approximately 250 meters outdoors.
6G leverages ultra-wideband frequencies and has a relatively short range through power loss
To solve the issue, LG, Fraunhofer HHI, and Fraunhofer Institute for Applied Solid State Physics (IAF) have co-developed a power amplifier and a receiver low-noise amplifier.
The multi-channel power amplifier has an output of more than 20dBm, an increase of over 5dBm from the previous trial.
The receiver’s low-noise amplifier then minimizes noise generation for reception signals.
With the success of our latest demonstration, we are one step closer to realizing 6G speeds of 1 terabit (TB) per second in both indoor and outdoor urban areas,”
CTO and executive vice president of LG Electronics, Dr. Kim Byoung-hoon.
LG plans to announce the full results of its latest 6G communications test and present an overview of the technology’s development at the upcoming 6G Grand Summit, at the LG Science Park in Seoul on 23 September.
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, with commercialization of the technology slated for 2029.
