SKT is strengthening mobile communication quality in buildings and transportation by focusing on research in the field of transparent antennas and RIS technology.

SKT announced that it has succeeded in developing transparent antenna equipment and RIS (Reconfigurable Intelligent Surface) technology through over three years of research collaboration with chemical materials company Dongwoo Finechem.

They stated that the newly developed technology receives radio waves by attaching an antenna with a thin metal pattern in the form of a transparent film to glass, and that it can be installed so harmoniously with the surrounding environment that the antenna attached to the glass is imperceptible.

In addition, SKT announced on the 30th that it has completed verification of core RIS technology that can enhance 5G and 4G service quality through transparent antennas that can be attached to buses, subways, and building glass.

SKT stated that by utilizing transparent antennas and RIS technology, it can enhance wireless quality, expand mobile communication service coverage, and reduce power consumption by increasing energy efficiency. It can also be used to expand coverage inside buildings by reflecting specific frequency bands.

Recently, we successfully commercialized the application of transparent antennas to LTE modems used in public Wi-Fi on some city buses in the metropolitan area, and completed performance verification of transparent antennas for 5G data modems and RIS for high frequency bands at our Pangyo office.

SKT expressed its ambition to lead technological evolution by continuing related research and development to enable utilization in various communication services such as 5G and 4G, and to secure key technologies for mid-to-long-term evolution leading to 5G advancement and 6G evolution by continuing research in various environments.

Park Jong-kwan, Head of Infrastructure Technology at SKT, stated, “We will continue to discover leading global examples for enhancing wireless quality, such as advanced antenna technologies like transparent antennas and RIS, which are necessary for the advancement of 5G services and the evolution of 6G.”
