Rohde & Schwarz and VIAVI demonstrate 5G NR high-speed downlink IP data throughput using 8x FR1 and FR2 component carriers

Enhanced mobile broadband (eMBB) is the use case of 5G NR which supports the ever-increasing end user data rate and system capacity, as mobile devices integrate more and more internet-based services and applications. At MWC21, T&M specialists Rohde & Schwarz and VIAVI Solutions will demonstrate a 5G NR eMBB end-to-end test scenario in 5G SA mode (standalone 5G) exceeding for the first time a high-speed data throughput of 7.5 Gbps. The demonstration paves the way for upcoming data rates up to 10 Gbps. This high throughput rate means mobile subscribers will soon benefit from 4K video streams or augmented reality.

Leveraging their close cooperation on 5G NR implementation in their wireless test solutions, the T&M specialists Rohde & Schwarz and VIAVI Solutions 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.

The setup is based on the R&S CMX500 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 R&S CMX500 comes with ready-to-use servers for testing web, FTP, DNS or IMS services allowing easy setup. In this scenario, the R&S CMX500 enables upload and download throughput tests for the File Transfer Protocol.

Rohde & Schwarz and VIAVI have been working together to implement and test new 3GPP 5G NR features at the same time in order to further expedite the release of software features with quality to customers. Using the R&S CMX500 as network infrastructure emulator alongside the TM500 UE emulator is a versatile alternative to a real device. The cooperation ranges from RF performance testing, protocol stack verification of 3GPP Rel.16 features and to maximum IP data throughput tests. This enables both companies to provide their customers with a stable, mature and comprehensive 5G 3GPP feature coverage at an accelerated rate.

Rohde & Schwarz is showcasing eMBB end-to-end tests with VIAVI at Mobile World Congress 2021 from June 28 to July 1 at the Fira Gran Via in Barcelona in hall 3, booth 3K30. Additional activities around 5G NR device testing can be found online on the Rohde & Schwarz Signals webpage.
