LG brings 6G a step closer with latest test

1 min read

Electronics giant LG has achieved a major milestone in the commercialization of 6G with a successful outdoor test of 6G terahertz (THz) data over a distance of 320 meters.

According to LG, the test which took place on September 7 at the Fraunhofer Heinrich Hertz Institute (HHI) in Berlin was at a frequency range of 155 to 175 GHz.

LG said the successful test represents a big step forward in commercializing 6G THz in both indoor and outdoor urban areas since the reference cell coverage of base stations for urban macro cells is a distance of about 250 meters outdoors.

The test follows a similar outdoor test by LG last August that the transfer of 6G THz data over a distance of 100 meters.

6G leverages ultra-wideband frequencies and has a relatively short range. As a result of this it can experience power loss from transmission to reception.

To solve these problems, LG working in tandem with the Fraunhofer engineers co-developed a power amplifier capable of increasing transmission strength, and a receiver low-noise amplifier that improved incoming signal quality, the company said.

The team also utilized a receiver low-noise amplifier that minimized noise generation for the reception signal. These new technologies were integrated into LG’s latest module design, which the company said was capable of future IC (Integrated Circuit) fabrication, helping ease the path towards future commercialization.

“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,” said Dr Kim Byoung-hoon, CTO and executive vice president of LG Electronics.

“LG will continue to cooperate with research institutes and industry innovators to further solidify its leadership in 6G technology. We expect 6G to be a major driver of future business and new user experiences, and there is no place we’d rather be than at the forefront of its development.”

LG plans to announce the full results of its latest 6G communications test and present an overview of the technology’s development so far at the upcoming 6G Grand Summit, set to take place at the LG Science Park in Seoul on September 23.
