Together with Rohde & Schwarz, HEAD acoustics has successfully verified communication quality of 5G (VoNR)-capable devices. For the test solution, the interoperability between the hardware platform labCORE, the measurement and analysis software ACQUA and the latest generation of the R&S CMX500 wideband radio communication tester was verified. The setup allows simulation of a voice connection in both 5G (VoNR) and 4G (VoLTE) networks. 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.
Connection establishment in a 5G mobile network
Mobile phones under test can register with the integrated IP multimedia subsystem (IMS) server of the R&S CMX500 platform via the simulated 4G or 5G mobile network, depending on the use case. labCORE is connected through wired Ethernet using the integrated IP forward mode of the IMS server, specifically developed for this use case. This allows users to forward the voice data of a call established with the R&S CMX500 directly to labCORE for detailed voice quality analysis. In this mode, the system fully supports the 5G speech codecs EVS (Enhanced Voice Service), AMR-WB and AMR-NB. Using the test suite TS 26 131-32 for use with the measurement and analysis software ACQUA developed by HEAD acoustics, 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 rollout of 5G voice services.
Christoph Pointner, Senior Vice President Mobile Radio Testers at Rohde & Schwarz, says: "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."
"With the interoperability to the Rohde & Schwarz solution, we can provide our customers with a crucial supplier we are compatible with in shortest time," adds Christian Schüring, Head of Sales Department Telecom at HEAD acoustics GmbH. "This is an important step to measure and optimize the communication quality of 5G-enabled devices."
As a world's leading provider of holistic solutions for measuring, analyzing and optimizing communication quality, HEAD acoustics is addressing the challenges of future 5G and 6G functions with industry partners early on to offer customers in the entire communications industry even more comprehensive test solutions.
