Voice and audio analysis expert HEAD acoustics has selected the 5G test solution from Rohde & Schwarz for verification of voice and audio services of 5G mobile devices. The upgraded R&S CMX500 5G one-box signaling tester features a significantly reduced footprint and easier handling combined with debugging and analysis capabilities, which support the end users’ testing of voice services.
Another important feature is the Bearer and Flow Monitor that enables the user to see various Quality of Service (QoS) flows such as video or audio live via the connection. For instance, all audio properties are visualized, including bitrate and codec within the flow stream. The HEAD acoustics labCORE system is connected via Ethernet using the integrated IP forward mode of the internal R&S CMX500 IMS server, specifically developed in a joint cooperation for this use case. This allows users to forward the voice data of a call established to the labCORE system for detailed voice quality analysis. However, an analog connection with the labCore system is also supported in case the labCore system is not equipped with the IP interface.
