LG U+ has started to verify the key antenna technology required to implement the 6G mobile communication. This technology, called RIS, is a smart antenna that can provide transmission or reflection effects according to the received radio wave characteristics. In order to implement 6G, this RIS technology is essential because it requires a very high frequency in the THz band, which has never been used in mobile communication.

This technology is a kind of intelligent technology that transmits the base station signals to the inside of buildings and helps to bypass obstacles. It is expected that higher quality communication services will be provided in urban and indoor spaces with many obstacles.

LG U+ has been collaborating with various companies such as Nokia on the 6G RIS technologies since last year.

Sang-heon Lee, LG U+ NW Advance Development Manager, said, "If the actual usability of RIS is verified, it is expected to be used not only for 6G but also for 5G quality improvement."

The telecommunications industry around the world is focusing on RIS technology and making all-out efforts to secure 6G leadership. For example, NTT DoCoMo, a Japanese telecommunications company, has also announced plans to improve indoor coverage based on RIS.
