KT, a major Korean mobile carrier, said Wednesday it has joined hands with Finnish telecommunications firm Nokia for sixth-generation (6G) communications network research.

The two companies signed a memorandum of understanding aimed at co-developing open radio access network and ultra-wideband wireless technologies as part of efforts to take global leadership in the 6G market, expected to span out from 2030, KT said.

"With the 6G partnership with Nokia, KT looks forward to leading the development of telecommunications technologies directly connected to the next-generation cloud and artificial intelligence," said Lee Jong-sik, head of KT's network research center. (Yonhap)
