• Samsung Electronics and KT Corporation Verify X-MIMO Technology in 7 GHz Band for 6G Development on February 20, 2026 AI Summary AUDIO Play Download Share open Print Samsung Electronics today announced it has reached a significant milestone in 6G development, successfully verifying eXtreme multiple-input multiple-output (X-MIMO) technology in the 7 GHz band - a key candidate frequency for future 6G networks - with KT Corporation (KT) and Keysight Technologies. • Through outdoor field testing, the companies demonstrated a peak downlink data rate of up to 3 gigabits per second (Gbps) in the 7 GHz band using X-MIMO. • The breakthrough was enabled by ultra-high-density antenna technology that integrates significantly more antenna elements into equipment of comparable size. • Considered a foundational component of 6G, ultra-high-density antenna technology achieves four times the antenna density of current 5G systems. • Overcoming 7 GHz Band Challenges As data demands surge due to advancements in AI, immersive services and fixed wireless access (FWA), 6G is becoming increasingly important in meeting evolving global connectivity needs. • The 7 GHz band stands out as a promising candidate for future communications, offering an optimal balance of coverage and capacity between the 5G 3.5 GHz band and millimeter-wave frequencies.

Article Summaries:

  • Samsung Electronics and KT Corporation announced that they have successfully verified eXtreme multiple‑input multiple‑output (X‑MIMO) technology in the 7 GHz band, a key frequency candidate for 6G networks. In outdoor field tests, the partners demonstrated a peak downlink data rate of up to 3 Gbps using eight simultaneous data streams from a 6G base‑station prototype with 256 digital ports. The breakthrough relies on ultra‑high‑density antenna arrays that provide four times the antenna density of current 5G systems, helping to balance coverage and capacity at 7 GHz. The test, conducted at Samsung’s Seoul R&D campus with Keysight Technologies, marks a foundational step toward commercial 6G deployment.
