NEW DELHI: MediaTek and Samsung have successfully completed the industry's first test of a 3Tx 5-layer uplink configuration, marking a significant milestone in 5G network technology. The demonstration combined MediaTek's M90 5G modem platform with Samsung's advanced network solutions, including its virtualized Radio Access Network (vRAN), Massive MIMO radios, and macro radio systems.

The trial utilized a multi-band setup featuring the n66 (1.7 GHz) band as the primary cell alongside dual n77 (3.7 GHz) carriers across five uplink layers. Using a 30 MHz bandwidth on the n66 band and a combined 200 MHz bandwidth on the n77 spectrum, the companies achieved a peak uplink throughput of 670 Mbps.

The breakthrough builds on earlier advancements in three-transmit antenna (3Tx) technology and is designed to improve uplink capacity, spectral efficiency, and network performance for data-intensive applications. The companies said the technology will support richer cloud services, immersive digital experiences, and enhanced Fixed Wireless Access (FWA) connectivity.

Samsung's software-based vRAN architecture and Massive MIMO technology played a key role in optimizing resource allocation, managing multiple frequency bands, and improving network efficiency while serving multiple users simultaneously.

MediaTek said the achievement highlights the growing importance of high-speed uplink connectivity as demand increases for cloud computing, ultra-high-resolution content, real-time collaboration tools, and next-generation digital services.
