AMR Testing on GSM Base Stations with R&S CMU300
26-Jul-2005 | AN-No. 1CM59
The user can select between the supported codecs, such as EVS and AMR-WB or AMR-NB with their respective codec rates. To test audio quality during a call, an analyzer is required. It must be able to generate and analyze audio waveforms using the latest methodologies according to PESQ or POLQA, whereby POLQA is used for audio quality measurements during VoNR and VoLTE calls.

Rohde & Schwarz and HEAD acoustics demonstrate test solution for 5G voice over NR (VoNR) voice serviceTogether with HEAD acoustics, Rohde & Schwarz has 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. 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.
