The webinar illustrates on the R&S®CMW500 wideband radio communication tester how the specified RF test cases can be performed and automated, and how the results can be interpreted.
Bluetooth® Low Energy channel sounding validation
06-Sep-2023
This application note and associated application software may be used to conduct psychoacoustic speech quality evaluation for Voice over LTE (VoLTE) connections. The measurements are based on recommendations ITU-T P.862 and ITU-T P.863. The included software sequence performs decoder/encoder calibration, connection setup for the UE under test and subsequent speech quality analysis.
