Codec option improves analysis of VoLTE enhanced voice services
EVS, which was specifically designed for broadband voice calls in mobile communications systems such as LTE, noticeably improves the audio quality of phone calls.
The R&S CMW500 emulates an LTE network while the R&S UPV uses objective criteria to analyze the audio and voice quality of the mobile device’s EVS-based VoLTE services. The measurements are based on the mean opinion score (MOS) method using the standardized perceptual objective listening quality analysis (POLQA) algorithm.
The R&S CMW500 offers users such as network operators and mobile device manufacturers a fully integrated, user-friendly IMS test environment that can be used to quickly and easily test VoLTE EVS calls and other IMS functions on mobile devices.
At this week’s Mobile World Congress in Bacelona Rohde & Schwarz is presenting the company’s test setup for analyzing VoLTE enhanced voice services. The R&S CMW-KS104 codec for enhanced voice services option for the R&S CMW500 wideband radio communication tester is now available for ordering. To use this option, the R&S CMW500 must be equipped with an integrated data application unit, an audio board and the IMS server option.
