Leveraging their close cooperation on 5G NR implementation in their wireless test systems, Rohde & Schwarz and VIAVI have successfully accomplished high-speed data throughput end-to-end test of 5G NR eMBB. By achieving 7.5 Gbps, the two companies herald the new age of high data throughput, showing that it is possible to validate very high data rate applications over a 5G network without performance compromises.
This high throughput rate means mobile subscribers will soon benefit from 4K video streams or augmented reality. The demonstration paves the way for upcoming data rates up to 10 Gbps.
The setup is based on theCMX500 wideband radio communication tester by Rohde & Schwarz and the TM500 network tester for user equipment (UE) emulation by VIAVI. In the demo, the instruments simulate a standalone 5G cellular network with 8x downlink carrier aggregation in NR dual connectivity (NR-DC) using 1xCC in FR1 and 7xCC in FR2 with a modulation scheme of 256QAM on all carriers. Two remote radio heads in the setup are used to upconvert the signals to 5G FR2 frequencies.
End-to-end testing evaluates the data throughput speed from the built-in simulated server and base station to the device under test in a well-defined network environment. The application test enabler of the CMX500 comes with ready-to-use servers for testing web, FTP, DNS or IMS services allowing easy setup. In this scenario, the CMX500 enables upload and download throughput tests for the File Transfer Protocol.
