Samsung Electronics has secured key technology for 6G commercialization by achieving 3Gbps in the 7GHz band.

Samsung Electronics announced on the 20th that it has succeeded in verifying eXtreme-MIMO technology in the 7GHz band, which is attracting attention as a key candidate frequency for 6G, the next-generation mobile communication, together with KT and Keysight Technologies.

This achievement is considered an important milestone that secures core technologies for the implementation of 6G communication and strengthens leadership in the global 6G ecosystem.

Ultra-high density multi-antenna technology is a technology that integrates multiple antennas into a single system at high density to maximize signal efficiency and dramatically increase data throughput.

Samsung Electronics developed a prototype 6G base station with the technology applied, and conducted performance verification using Keysight's test 6G terminals in a communication testbed built by KT that is similar to a real-world environment.

As a result of verification, the research team achieved a maximum transmission speed of 3Gbps in a downlink environment where data is transmitted from a base station to a user terminal.

This is about twice as fast as commercial 5G and is the industry's highest speed achieved in the 7GHz band.

This demonstrated that technical limitations such as signal attenuation and reduced communication range occurring in the high-frequency band can be overcome.

The 7GHz band isWhile it offers a wider bandwidth than 3.5GHz of 5G, enabling ultra-high-speed data transmission, it has the disadvantage of being vulnerable to obstacles as the frequency increases.

Samsung Electronics, KT, and Keysight have secured communication range and stability comparable to 5G by utilizing ultra-high-density multi-antenna technology to simultaneously transmit eight data streams.

This technology verification is expected to contribute to the realization of 6G-based ultra-high-speed and ultra-low-latency communication in fields with rapidly increasing data demand, such as AI, extended reality (XR), and immersive media.

"Through this collaboration, we have confirmed the potential for innovative transmission speed improvements in next-generation communications," said Jin-Gook Jeong, Head of Samsung Electronics' Next-Generation Communication Research Center. "We will continue to lead future network technologies to realize new services and user experiences in the 6G era."
