T&M solution
The R&S®CMWrun software is the right overall automation tool for audio/speech performance testing of VoLTE and legacy standards. In this setup, the R&S®CMW500 callbox tester acts as a 2G/3G and LTE network emulator. It provides integrated IMS service support plus an audio board with the standard specific speech codecs for voice calls. The R&S®UPV audio analyzer supports PESQ/POLQA algorithms for objective audio analysis.
Research and development testing
With just a few mouse clicks, the user can define a testing campaign that includes the key signaling parameters and conditions in an LTE network with their possible impact on the audio quality and user experience. Signaling parameters that are integrated into the R&S®CMW500 and can be configured via R&S®CMWrun include: integrated IMS server to establish a voice or video call, RoHC, SPS, TTI bundling, dedicated bearer and QoS, IP environment (IPv4 and IPv6) delay, jitter, packet losses and fading profiles.
The audio testing solution is available in the following standard-specific R&S
