Samsung Electronics, KT, and Keysight Achieve Top Speeds with 6G Ultra-High-Density Multi-Antenna Technology

Twice the Speed of 5G in the 7 GHz Band
"We Will Continue to Secure Leadership in the Global 6G Ecosystem"

Samsung Electronics announced on the 20th that, together with KT and Keysight Technologies (hereinafter Keysight), it has successfully validated ultra-high-density multi-antenna technology in the 7 GHz band, a core frequency band for 6G communication standards.

Ultra-high-density multi-antenna technology integrates multiple antennas into a single system to improve signal efficiency and maximize data throughput. Samsung Electronics developed a base station prototype applying this technology, and validated its performance by using Keysight's test 6G device in a communication environment built by KT to closely resemble real-world conditions.

As a result, the research team achieved a maximum transmission speed of 3 Gbps, which is among the highest in the industry, when sending data from the base station to the user device, thereby securing a core technology for 6G communications.

The 7 GHz band used in the validation is considered a core 6G frequency because it offers a wider bandwidth compared with the existing 3.5 GHz band used for 5G. However, as frequencies become higher, the signal coverage range decreases, which created the need for ultra-high-density multi-antenna technology as a key solution to overcome this limitation.

Samsung Electronics stated that through this technology validation, it has confirmed that stable communication coverage and ultra-high-speed data transmission are possible even in the 7 GHz band. The company expects this to contribute to the realization of data-intensive services such as artificial intelligence (AI) and extended reality (XR).

Going forward, the company plans to expand collaboration with global telecommunications operators and equipment vendors, continuing to develop core 6G technologies and build out the 6G ecosystem.

Jeong Jinkuk, Head of the Next-Generation Communications Research Center at Samsung Electronics, said, "We will continue to lead the way in securing future network technologies so that various services and user experiences of the 6G era can be realized."

Lee Jongsik, Head of the Future Network Research Institute at KT, said, "This validation is an important turning point in preparing for 6G commercialization, as it has enabled us to secure a core foundational technology needed to implement ultra-high-speed, immersive services by ensuring stable and high capacity in the 7 GHz band."
