Samsung Network, in collaboration with MediaTek, conducted a test of a standalone 5G uplink network using three antennas (3Tx). The test successfully achieved super fast upload speeds of up to 363 Mbps.
The testing itself utilized Samsung’s C-Band Massive MIMO radio, virtualized Distributed Unit (vDU), and 5G core. Meanwhile, MediaTek contributed testing devices with its latest M-80-based CPE chipset.
Interestingly, the device used three antennas (3Tx) simultaneously on the 1,900MHz, 3.7GHz, and 3.7GHz channels. Current smartphones or CPE devices typically support only two antennas (2Tx).
Samsung explained that this approach can enhance upload speeds, data transmission efficiency, and overall network performance. The 363 Mbps upload speed nearly matches the highest download speed of 5G, which was previously significantly different.
High upload speeds can open up various new opportunities, including enabling on-the-go high-resolution live streaming. Of course, it will take some time for this technology to reach consumer devices, including the smartphones we use every day. Let’s wait and see.
