Samsung Electronics (KRX:005930), along with KT (KRX:030200) and Keysight Technologies, verified eXtreme-multiple input multiple output (eMIMO) technology in the 7GHz band, according to a Friday release.
The 7GHz spectrum is considered a core frequency for 6G networks, offering broader bandwidth and considerably higher data speeds compared with the 3.5GHz band currently used for commercial 5G services, the release said.
Shares of KT rose nearly 4% in recent trade.
