This Rohde & Schwarz webinar presents the technical background to VoLTE (based on IMS) and explains how to measure voice quality in live networks. It also illustrates the impact of radio conditions and IP impairments (e.g. jitter or audio delay) to audio quality. The main focus is on the field testing aspects of VoLTE.

One of the leading use cases for carrier network virtualization is the IP multimedia subsystem (IMS) core. Service providers, particularly mobile operators planning for voice over LTE (VoLTE), are looking toward network functions virtualization (NFV) to scale services up and down quickly and to better align costs with network usage.
