LG successfully demonstrated data transmission and reception in the wireless 6G terahertz (THz) spectrum over more than 100 meters in an outdoor situation.
In collaboration with Fraunhofer-Gesellschaft, Europe’s largest applied research laboratory, the company reached this technological milestone. Because 6G THz technology is only short-range and power loss occurs during antenna transmission and reception, one of the most difficult challenges in developing wireless 6G was to increase performance, which was required to generate a stable signal at ultra-wideband frequencies, LG explains in a statement.
This is why the performance amplifier developed by the Fraunhofer Institute for Applied Solid State Physics is a crucial component that contributed to the test’s success. In the frequency range of 155 to 175 GHz, the power amplifier can deliver a consistent signal output of up to 15 dBm.
LG has implemented adaptive beamforming technology and high-profit antenna switching with great success. The former adjusts the signal’s direction in response to changes in the channel and receiver’s positions. At the same time, the latter mixes and sends the output signals of many power amplifiers to specified antennas.
6G networks will offer considerably faster wireless transmission and communication with low latency and excellent dependability after worldwide standardization in 2025 and commercialization four years later.
According to LG, 6G will be a crucial component of the Ambient Internet of Everything, an emerging technology that recognizes human presence and preferences to make the home and business environment more sensitive, flexible, autonomous, and personalized based on user wants.
