Rohde & Schwarz combines the HEAD acoustics voice and audio quality analysis solution with its 5G test platform R&S CMX500 for verifying 5G mobile device voice and audio services.
The modular labCORE hardware and the ACQUA software, combined with the comprehensive testing toolset of the R&S CMX500 from Rohde & Schwarz, allow voice services testing in 5G (VoNR) and 4G (VoLTE) networks. The powerful combination enables manufacturers of 5G-capable devices to reliably test voice quality early before market introduction.
HEAD acoustics has fully integrated the latest releases of all relevant standards bodies, such as 3GPP, GSMA, and PTCRB for testing and verifying the speech performance of 5G VoNR terminals. The HEAD acoustics solution includes testing with all speech codecs and standardized performance testing under packet loss and jitter conditions. The HEAD acoustics labCORE system connects to the R&S CMX500 through wired Ethernet using its internal IMS server's integrated IP forward mode, allowing users to forward the voice data of a call established to the labCORE system for detailed voice quality analysis.
The combination with the leading-edge Rohde & Schwarz solution allows 5G NR device testing in standalone (SA) and non-standalone (NSA) TDD and FDD modes. The R&S CMX500 supports 5G FR1 and mmWave (FR2) frequency bands and provides the required features for VoLTE and VoNR calls. The Bearer and Flow Monitor enables users to see various Quality of Service (QoS) flows and visualizes all audio properties, including bitrate and codec, within the flow stream.
Christian Schüring, Head of Sales Telecom at HEAD acoustics GmbH, states: "The combination of the HEAD acoustics test solution with the R&S CMX500 one-box design dramatically simplifies cabling and handling. This combination becomes an even more powerful, convenient, and comprehensive tool."
Christian Hof, Senior Product Manager of Mobile Radio Testers at Rohde & Schwarz GmbH & Co. KG, states: "The cooperation with HEAD acoustics facilitates the seamless integration of acoustics and radio transmission testing. It greatly adds value to our products and significantly simplifies our common customers' work."
