Rohde & Schwarz has declared to be presenting test solutions for “5G reality & evolution” as the focal point at Mobile World Congress 2021 (MWC21).
When it comes to cellular device testing, Rohde & Schwarz will showcase the following highlights at the industry’s premier event:
High-throughput eMBB end-to-end testing
At MWC21, Rohde & Schwarz demonstrates, together with VIAVI, its R&S CMX500 radio communication tester and the VIAVI TM500 network tester in a 5G NR eMBB end-to-end test scenario in 5G SA (standalone) mode, exceeding for the first time a high-speed data throughput of 7.5 Gbps.
VoNR audio quality testing
Even with 5G, voice services will remain a key use case for mobile subscribers. Rohde & Schwarz has teamed up with HEAD acoustics to verify the quality of voice services over 5G NR. At MWC21, the two companies demonstrate a test solution based on the latest generation of the R&S CMX500 radio communication tester, combined with the labCORE hardware platform from HEAD acoustics and their ACQUA measurement and analysis software.
Conformance testing and carrier acceptance tests
With an R&S CMX500 based test system, Rohde & Schwarz supports carrier acceptance tests such as performance quality analysis (PQA), network protocol tests (NPT) and LBS tests in 5G FR2.
At MWC21, Rohde & Schwarz demonstrates a typical carrier acceptance test case: heat dissipation of a mobile device as a function of data throughput.
Multireflector compact antenna test range
With the R&S ATS1800M, Rohde & Schwarz is introducing a CATR based mmWave test chamber that provides a multi-reflector setup with a small footprint to test with low measurement uncertainty.
This solution is ideal for characterizing devices in the presence of multiple signals coming from different directions using a full black-box test approach – a typical test scenario in radio resource management (RRM) testing that is made possible thanks to a total of four CATR reflectors in the R&S ATS1800M, each one providing a quiet zone with an unrivaled size of 30 cm in diameter.
mmWave testing on the factory floor
For this, Rohde & Schwarz has developed the R&S CMPQ test platform. Manufacturers setting up their production lines can configure the individual components and the overall system independently to create customized solutions for FR2 testing.
The R&S CMPQ consists of an R&S CMP200 radio communication tester, R&S CMPHEAD30 mmWave remote radio heads and an R&S CMQ200 shielding cube.
