Samsung not only makes smartphones but also develops the telecommunications networking equipment used to build cellular networks that phones connect to. The South Korean firm has now announced that it has reached a major milestone in verifying a technology it developed that could play a vital role in deploying 6G cellular networks.
Samsung Electronics has successfully verified eXtreme multiple-input multiple-output (X-MIMO) technology in the 7GHz band in collaboration with Keysight Technologies and KT Corporation (KT). They achieved a peak download speed of 3Gbps in the 7GHz band using X-MIMO. They used an ultra-high-density antenna system that incorporates significantly more antenna elements into equipment while maintaining a similar physical size to systems based on older technologies.
X-MIMO is considered a foundational component of 6G telecommunications networks and uses four times the number of antenna elements compared to 5G networks. The 7GHz band is emerging as a strong candidate for 6G because it offers a balance between capacity and coverage. It sits between 5G’s 3.5GHz mid-band spectrum and its millimeter wave bands.
The verification was conducted at Samsung Electronics’ Seoul R&D Campus. Researchers measured data transfer rates while simultaneously transmitting eight data streams from the base station to a single user device. To replicate real-world network conditions, Samsung worked with KT to create an outdoor wireless test environment.
The test also used Samsung’s 6G base station prototype with 256 digital ports and Keysight’s 6G terminal testbed.
JinGuk Jeong, Executive Vice President and Head of the Advanced Communications Research Center at Samsung Research, said, “Through our collaboration with KT and Keysight, we have demonstrated the potential for significant improvements in data rates for next-generation communications. We remain committed to pioneering future network technologies that will enable diverse services and enhanced user experiences in the 6G era.”
