Combining the CMW500 wideband radio communication tester, which emulates a LTE network, and the UPV Audio Analyzer, Rohde & Schwarz has developed the world’s first VoLTE test system for audio quality measurements, according to the company.

Combining the CMW500 wideband radio communication tester, which emulates a Long-Term Evolution (LTE) network, and the UPV Audio Analyzer, Rohde & Schwarz has developed the world’s first Voice over LTE (VoLTE) test system for audio quality measurements, according to the company. Users can perform audio quality measurements based on PESQ1 during an active IMS voice call on the simulated LTE network. Rohde & Schwarz says that with the combination of the R&S UPV Audio Analyzer and R&S CMW500 Wideband Radio Communication Tester, network operators can pre-test VoLTE-capable devices and build confidence in performance before taking this step in their LTE deployments.
