The company has announced (via PhoneArena) over in Korea that they will be establishing a 6G Research Center together with KAIST. While it does seem like it is very early to begin researching 6G, especially since 5G smartphones aren’t even in the market yet, LG claims that they want to pre-empt it.
According to Professor Cho Dong-Ho (translated from Korean), “It is important to improve the competitiveness of Korea’s mobile communication technology and to prepare for the future industry after 10 years from the start of 6G mobile communication technology development.” Basically it sounds like LG is hoping to keep themselves competitive by hopping on the 6G train way before everyone else does.
It is definitely way too early to tell what kind of changes 6G will bring to the table. As it stands there are companies that are currently exploring what 5G can do, so research into 6G is probably quite a long ways away.
