Rohde & Schwarz Tests VoLTE and Audio Quality

Rohde&Schwarz demonstrated voice over LTE (VoLTE) and audio quality measurements with the R&S®CMW500 wideband communication tester and the R&S®UPV audio analyzer at LTE North America 2011. For the demonstration a commercial LTE USB dongle in collaboration with an IMS client running on a PC was used to simulate a VoLTE-capable device. This setup registered to an IMS server via LTE to establish an IMS call. The audio quality measurements carried out have been in line with the PESQ® standard.

Rohde&Schwarz also demonstrate the SMS over IMS Verification.
