Ericsson, Qualcomm to demo VoLTE to WCDMA voice handover via SRVCC

At Mobile World Congress next week, Ericsson and Qualcomm will conduct a live demo of seamless voice call handoff between LTE to WCDMA voice networks. 

The SRVCC (Single Radio Voice Call Continuity) demo highlights the ability to use fewer radio components to hand off calls between LTE and WCDMA networks.   A demo illustrates there is no change in codecs between LTE and WCDMA 3G networks; i.e., AMR-WB is used throughout the call.

According to Wikipedia, WCDMA is used in Japan and better known/marketed as UMTS and known as 3GSM around the world.
