Samsung Electronics announced Friday that it has achieved record-breaking data transmission speeds in the 7-gigahertz (GHz) band, a critical frequency for future 6G networks. This milestone was accomplished in a joint test conducted with Korean telecom operator KT and US-based electronics test equipment company, Keysight Technologies.
The cutting-edge ultra-high-density multiple-antenna technology utilizes massive multiple-input multiple-output (MIMO) architecture. This advanced system integrates a large number of antennas into a single unit, significantly enhancing efficiency and speed of data transmission.
As part of this collaborative effort, Samsung developed a prototype base station incorporating the ultra-high-density antenna technology. KT provided a simulated network environment to facilitate testing, and Keysight Technologies supplied its advanced 6G test equipment for verification purposes.
The companies successfully achieved a downlink speed of 3 gigabits per second (Gbps), representing the fastest recorded results in the 7GHz band. This achievement was made possible by simultaneously transmitting eight data streams from the base station to a user device.
The 7GHz band is considered a highly promising frequency range for 6G technology due to its wider bandwidth and potential for higher data rates compared to the 3.5GHz band currently used in 5G networks. While higher frequencies typically face challenges related to shorter transmission ranges and increased sensitivity to physical obstacles, this experiment addressed those concerns.
The partners highlighted that the innovative X-MIMO configuration effectively overcame these limitations, delivering coverage comparable to existing 5G networks while simultaneously achieving substantial improvements in transmission speeds. Samsung anticipates that these advancements will significantly contribute to the development of 6G technology, especially in sectors experiencing rapid growth in data demand, such as artificial intelligence (AI) and extended reality (XR).
“Through our collaboration with KT and Keysight, we have confirmed the potential for further breakthroughs in transmission speed for next-generation communications,” stated Jeong Jin-guk, Head of Samsung’s Advanced Communications Research Center. “We will continue to lead the development of future network technologies for the 6G era.”
