LG Electronics unveiled 6G-related technologies, which are core technologies for future connectivity, at 'Institute of Electrical and Electronics Engineers (IEEE) International Conference on Communications (ICC) 2022' on the 17th. At this conference, LG Electronics introduced ▲ a power amplifier device for transmitting and receiving 6G terahertz (㎔) wireless data and ▲ Full Duplex Radio (FDR) transmission/reception technology that can maximize frequency efficiency.In a keynote speech, Byung-hoon Kim, CTO of LG Electronics said, “We will strengthen our capabilities in various fields such as mobility, metaverse, and robots by increasing our competitiveness in 6G and AI technologies.”LG Electronics exhibited its future car ‘LG Omnipot’ at the event. The LG Omnipot is a concept model of future mobility that interprets a vehicle as a newly expanded space of a home. It can be used as an office space or as a personal space where you can enjoy watching movies, exercising, camping, etc.

KT SAT's satellites and antennas enable communication services at any time anywhere in the sea, land or air, and the company is engaged in various overseas satellite launch projects.Kyung-il Choi, CTO of KT SAT explained that the size of the communication network to be built is expected to increase in the 6G era, and that the satellite network should be added to the ground network in order to provide stable and fast communication services. KT SAT also expressed its will to lead the market flow through international cooperation and satellite technology innovation in the space exploration competition ahead of the introduction of 6G. Hancom Inc. announced on May 26 that its low-orbital earth-observing satellite 'Sejong 1' has entered its target orbit. Hancom Group is also expanding its business to the field of communication infrastructure technology to keep pace with the era of 6G mobile communication, of which technology standardization is being progressed on the premise of using communication satellites. Hancom Inspace is expected to play a key role in this plan. On the 11th, the company was selected as the main operator of the 'Development of Ultra-Small Communication Satellite System for Demonstration of 6G Low-Orbital Communication' project among the space innovation projects of the Ministry of Science and ICT.

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.   

Samsung Electronics and LG Electronics are spurring the development of 6G technology, which is expected to be commercialized in 2028. Since the establishment of the Next-Generation Communication Research Center under Samsung Research in 2019, Samsung Electronics has been conducting researches on 6G prior technologies, and is working hard not to lose its leadership in 6G by meeting with the CEO of US Verizon. In addition, Samsung Electronics and Korea University are planning to proactively foster professionals who will lead the telecommunications market by linking the 'next-generation communications department' that deals with next-generation communications technologies, including 6G, to employment of electric and electronic engineers.   LG Electronics has the core technology of 6G mobile communication, such as being the first in the world to successfully transmit communication signals over 100m in a straight line outdoors using the 6GHz frequency band. LG Electronics established a 6G research center jointly with KAIST in 2019, and was selected as the chairman of ‘NGA’ organized by the American Telecommunications Industry Association (ATIS). In NGA, LG Electronics is in charge of discovering 6G use cases and establishing related technical requirements.   Korea's three major telecommunication companies, SKT, KT, and LGU+, are also actively conducting R&D to prepare for the 6G era, and are also collaborating with companies. SKT is conducting R&D on major 6G technologies in partnership with Samsung Electronics, Nokia, and Ericsson, and KT is researching 6G technologies with Seoul National University's New Media and Communication Research Center. LGU+ is working on national projects with ETRI, KAIST, and LG Electronics to develop 6G technologies.
