Voice over LTE 2014: Finally, the starting point
2014: Finally, the starting point
This report provides an insight into the Voice over LTE market.
More specifically, we shall see the rationale for using the VoLTE solution rather than keep relying on good old circuit-switch technology, and understand exactly where mobile carriers are in terms of embracing it.
We shall thus discern the challenges that operators face in choosing this solution as well as the opportunities that it represents.
