Through the exams, Samsung and KT stated they recorded peak downlink speeds of as much as 3 Gbps within the 7 GHz band utilizing X-MIMO
In sum – what to know:
3 Gbps at 7 GHz – Area testing utilizing X-MIMO delivered peak downlink speeds of as much as 3 Gbps, demonstrating the efficiency potential of the 7 GHz band for future 6G techniques.
Density enhance – Extremely-high-density antenna design integrates roughly 4 occasions the antenna components of present 5G techniques, addressing propagation challenges at increased frequencies.
256-port prototype – Trials used Samsung’s 6G base station prototype with 256 digital ports and eight simultaneous information streams in outside circumstances.
Korean vendor Samsung Electronics introduced it has verified eXtreme multiple-input multiple-output (X-MIMO) expertise within the 7 GHz band in collaboration with Korean service KT Company and U.S. agency Keysight Applied sciences.
The businesses performed outside discipline testing to evaluate efficiency in a frequency band extensively thought-about a candidate for future 6G networks.
Through the exams, the companions recorded peak downlink speeds of as much as 3 Gbps within the 7 GHz band utilizing X-MIMO. The setup relied on ultra-high-density antenna expertise, integrating the next variety of antenna components into tools of comparable measurement. In response to the businesses, this strategy permits roughly 4 occasions the antenna density of present 5G techniques.
The 7 GHz band is considered as providing a stability between protection and capability, positioned between mid-band 3.5 GHz spectrum and millimeter-wave frequencies. Nonetheless, increased frequencies sometimes face shorter propagation distances. The businesses stated X-MIMO compensates for this limitation by rising antenna density and bettering throughput whereas sustaining protection akin to 5G.
Testing occurred at Samsung’s Seoul R&D campus, the place engineers transmitted eight simultaneous information streams from a base station to a single system. The trial used Samsung’s 6G base station prototype outfitted with 256 digital ports and Keysight’s 6G terminal testbed. KT supported the creation of an out of doors wi-fi take a look at setting to mirror real-world circumstances.
“The validation of ultra-high-density antenna expertise efficiency within the 7 GHz band marks a important step towards 6G commercialization. By securing secure, high-capacity operation in high-frequency bands, we’ve got established a foundational expertise for enabling ultra-fast, immersive companies,” stated Jong-Sik Lee, government vp and head of Future Community Laboratory at KT Company.
In December 2025, Samsung and KT additionally validated AI-based radio entry community optimization expertise in a business setting and proceed to collaborate on uplink protection analysis.
The companions performed a discipline take a look at with roughly 18,000 customers in choose areas of Seongnam, Gyeonggi Province, in South Korea, that includes various environmental circumstances. The AI-RAN expertise was utilized to customers who had repeatedly skilled service disruptions, permitting the groups to determine recurring challenge patterns and develop user-specific community configurations.
