Looking forward: 5G wireless networks are still in their infancy, but that doesn’t stop the leading mobile experts from exploring what comes next. LG demonstrated wireless transmission and reception of 6G terahertz (THz) data at a distance of 320 meters outdoors. The feat occurred at the Fraunhofer HHI in Berlin, Germany, on September 7 with a frequency range of 155 to 175 GHz.
The demo is a big leap compared to LG’s last public test in August 2021 when it demonstrated that 6G THz data could be transmitted outdoors at a distance of 100 metres.
To circumvent the relatively short term of 6G, LG, Fraunhofer HHI, and Fraunhofer Institute for Applied Solid State Physics (IAF) have developed a power amplifier that increases transmitter power and a low-noise receiver to improve the quality of the incoming signal.
The LG multichannel power amplifier used in the most recent test had an output of over 20 dBm, well above the ~5 dBm used in the previous demo.
Dr. Kim Byung-hun, chief technology officer and executive vice president of LG Electronics, said the presentation brings them one step closer to achieving 6G speeds of 1 terabyte per second in both indoor and outdoor urban areas.
Notably, LG did not share how fast it reached in the test. Instead, the company will reveal the full results of its testing and provide an overview of the technology at the upcoming major 6G summit, scheduled to be held at LG Science Park in Seoul on September 23.
6G is still several years away. In its press release, LG said that discussions regarding the network standard are not expected to begin until around 2025. The technology is scheduled to be commercialized in 2029. When it arrives, it promises to deliver much faster data transfer speeds with improved latency and higher reliability. Then again, we’ve had that streak before so it’d probably be best to hold back your enthusiasm until he gets here and sees what he can do in the real world.
