Voice and SMS in LTE

This white paper summarizes the technology options for supporting voice and short message service (SMS) in LTE, including circuit switched fallback (CSFB), SMS over SGs, and voice over LTE (VoLTE). It includes background information on the standardization process, and the commercial implications for the different options. The white paper also addresses test and measurement requirements…

Webinar: Video over LTE

This webinar will illustrate how to establish and test the LTE video transmission link. Additionally, and equally importantly, it will show how the quality of the video transmission links can be measured under real-life propagation conditions and which metrics can be used to accomplish this task.

Voice over LTE (VoLTE) Speech Quality Measurements

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, respectively. The CMWrun example sequences perform decoder / encoder calibration, connection setup for the UE under test and subsequent speech quality analysis…
