Verizon, Ericsson and Qualcomm Technologies have made what they claim is a new U.S. record in 5G uplink speed reaching 480 Mbps using the sub-6 GHz spectrum.
High uplink speeds provide seamless data transmission from user devices to the cloud. This allows for low-latency interactions and reduces bottlenecks in data-heavy applications. The companies said that fast upload speeds are especially useful for time sensitive applications like:
- Healthcare diagnostics
- Remote robotics
- Live broadcasting
5G enhanced uplink capabilities in the trial will allow many businesses and industries to unlock AI, smarter automation, improving efficiency and immersive user experiences. This is important for video conferencing, cloud gaming, internet of things communications and augmented reality.
The trial
During the demonstration, Verizon, Ericsson and Qualcomm Technologies used 200 MHz of C-Band spectrum, employing 2x2 MIMO on each 100 MHz channel. This was hosted on Ericsson’s generation 4 RAN processor 6672 and massive multiple-input and multiple-input/multiple-output (MIMO) TDD antenna integrated radio AIR 6449.
MIMO uses multiple antennas on both the networks and the device to send and receive multiple data streams simultaneously.
The trial also employed time division duplex (TDD), a method that allows uplink and downlink to share the same frequency band but at different time slots. This technology can allocate time for uploads and downloads based on dynamically shifting network demands and improve spectral efficiency.
