Samsung Electronics and MediaTek have achieved a major breakthrough in wireless mobile capabilities by successfully testing 5G Standalone Uplink (UL) 2CC Carrier Aggregation (CA) with C-Band UL MIMO. This groundbreaking achievement has paved the way for enhanced connectivity and improved upload speeds, revolutionising the way we interact with our devices.
In today's fast-paced digital world, the demand for high-quality uplink performance is skyrocketing. Whether it's live streaming, multiplayer gaming, or video conferences, upload speeds play a crucial role in determining how quickly we can send data to servers or transmit high-resolution content to the cloud. With an increasing number of users seeking to document and share their experiences in real time, having a robust uplink capability has become more important than ever.

Traditionally, smartphones and customer premise equipment (CPEs) have been limited to supporting 2Tx antennas. However, this recent test demonstrated the remarkable potential of 3Tx antenna support, delivering enhanced mobile capabilities. By increasing the number of transmit antennas, not only are upload speeds significantly improved, but spectrum and data transmission efficiency are also enhanced, leading to an overall boost in network performance.
The successful test took place at Samsung's cutting-edge lab in Suwon, Korea. Leveraging Samsung's industry-leading 5G network solutions, including C-Band Massive MIMO radios, virtualised Distributed Unit (vDU), and core, the team collaborated with MediaTek, which provided their new M80-based CPE chipset. The test began with one uplink channel each at 1,900 MHz and 3.7 GHz, and then an additional uplink flow was added using MIMO on 3.7 GHz. The result was an impressive peak throughput rate of 363 Mbps, approaching the theoretical peak speed achievable with 3Tx antennas.
This achievement not only opens up new possibilities for faster and more reliable data uploads but also highlights the continuous efforts of industry leaders to push the boundaries of mobile technology. As we embrace a future of immersive experiences and real-time content sharing, this milestone brings us one step closer to seamless connectivity and enriches the way we navigate our digital lives.
