Samsung 6G trial hits 3 Gbps at 7 GHz with X‑MIMO

Samsung 6G trial hits 3 Gbps at 7 GHz with X‑MIMO
Samsung Electronics, working with KT Corporation and Keysight Technologies, has demonstrated 3 Gbps peak downlink in outdoor tests using an ultra‑dense antenna system and X‑MIMO in the 7 GHz band. The field trial took place at Samsung’s Seoul R&D Campus and pushed eight concurrent spatial streams from a base station to a single user device. The key enabler was a radio unit that packs roughly four times the antenna elements of today’s 5G massive MIMO gear into a similar physical footprint. Shorter wavelengths at 7 GHz make that density feasible without expanding the radio size.

iPhone RCS Launches in Korea with SK Telecom, KT and LG Uplus

iPhone RCS Launches in Korea with SK Telecom, KT and LG Uplus
Korea’s three national carriers have enabled Rich Communication Services (RCS) on iPhones via Apple’s recent iOS update, bringing Android–iOS parity for default messaging to a market long dominated by OTT apps. SK Telecom, KT, and LG Uplus now support RCS for iPhone users across Korea, extending capabilities that previously existed only on Android. RCS on iPhone is available on iPhone 11 series and newer models running the latest iOS update, with activation dependent on carrier support and user settings. Users gain modern chat features including group messaging with up to 100 Android participants, read receipts, typing indicators, replies, and support for richer media.

Korean Telecoms Launch 300B-Won AI & Semiconductor Fund
South Korea's government and its three national carriers are aligning fresh capital to speed AI and semiconductor competitiveness and to anchor a private-led innovation flywheel. SK Telecom, KT, and LG Uplus will seed a new pool exceeding 300 billion won (about $219 million) via the Korea IT Fund (KIF) to back core and foundational AI, AI transformation (AX), and commercialization in ICT. KIF, formed in 2002 by the carriers, will receive 150 billion won in new commitments, matched by at least an equal amount from external fund managers. The platforms lifespan has been extended to 2040 to sustain long-cycle bets.
