Samsung Electronics and MediaTek announced they completed the testing of 5G Standalone Uplink (UL) 2CC Carrier Aggregation (CA) with C-Band UL MIMO to reach top uplink speeds.
MediaTek and Samsung Electronics used three transmit (3Tx) antennas to improve upload experiences for consumers.
Improvement in uploading is important for live streaming, multi-player gaming and video conferences. Smartphone users rely on upload speeds of their mobile network to send data to gaming servers or transmit high-resolution videos to the cloud.
Current smartphones and customer premise equipment (CPEs) can only support 2Tx antennas. This industry-first demonstration validated the enhanced mobile capability of 3Tx antenna support. This approach improves upload speeds, enhances spectrum and data transmission efficiency, as well as overall network performance.
MediaTek and Samsung Electronics conducted the test in Samsung’s lab, based in Suwon, Korea. Samsung provided its 5G network solutions, including its C-Band Massive MIMO radios, virtualized Distributed Unit (vDU) and core.
The MediaTek test device featuring its new M80-based CPE chipset began with one uplink channel apiece at 1,900MHz and 3.7GHz, but added an extra uplink flow using MIMO on 3.7GHz. Both companies achieved a peak throughput rate of 363Mbps, an uplink speed that is near theoretical peak using 3Tx antennas.
“Faster uplink speeds bring new possibilities and have the potential to transform user experiences. This milestone further demonstrates our commitment to improving our customers’ networks using the most advanced technology available,” said Dongwoo Lee, Head of Technology Solution Group, Networks Business at Samsung Electronics.
“Enhancing uplink performance using groundbreaking tri-antenna and 5G UL infrastructure technologies will ensure next-generation 5G experiences continue to impress users globally,” said HC Hwang, General Manager of Wireless Communication System and Partnership at MediaTek.
