Rohde & Schwarz and HEAD acoustics have successfully verified voice services over 5G NR (VoNR).
The test solution employs the latest generation of the R&S CMX500 wideband radio communication tester, combined with the labCORE hardware platform from HEAD acoustics and their ACQUA measurement and analysis software. This setup allows simulation of a voice connection in both 5G (VoNR) and 4G (VoLTE) networks.
Christian Schüring, Sales Manager Telecom at HEAD acoustics, says: “The interoperability between our labCORE platform and the radio communication tester from Rohde & Schwarz is another milestone for our customers about testing and optimizing the quality of the communication of 5G devices.”
Christoph Pointner, Senior Vice President Mobile Radio Testers at Rohde & Schwarz, adds: “The successful collaboration between the two companies in the field of voice quality analysis for 2G, 3G and 4G, based on the R&S CMW500 platform, is extended to 5G with our R&S CMX500. The jointly verified test solution enables reproducible test results and allows device manufacturers and network operators to ensure an optimized 5G voice experience at an early stage.”
This enables manufacturers of 5G capable telecommunications devices to test the voice quality of their devices at an early stage before market introduction. The solution was presented at the Mobile World Congress in Shanghai in February 2021 for the first time.
The test solution from Rohde & Schwarz is based on the tried and tested R&S CMW500 wideband radio communication tester for 2G/3G/LTE and WLAN. The test scope for 5G NR can be upgraded with the R&S CMX500 radio communication tester, allowing 5G NR devices to be tested in both standalone (SA) and non-standalone (NSA) TDD and FDD mode.
The R&S CMX500 supports the sub6 GHz (FR1) and mmWave (FR2) frequency bands and provides all required technologies for VoLTE and VoNR calls in both SA and NSA mode.
Using the test suite of the ACQUA measurement and analysis software developed by HEAD acoustics for TS 26 131-32, the system fully covers all significant acoustical requirements. This reliable solution enables manufacturers of 5G capable telecommunications devices to test the voice quality of their devices at an early stage and prepare for the rollout of 5G voice services.
