Fourth generation (4G) data services are in the deployment stage, but is will be a few years until there is ubiquitous LTE coverage. Meanwhile, there are competitive threats emerging against incumbent carriers' core voice services. This is coming at a time when all bearer services (voice and data) are becoming marginalised due to market expectations, economic conditions, and a coming supply side expansion in terms of network capacity.

This research assesses the market drivers and outlook for VoLTE as well as carrier opportunities and challenges. The report forecasts VoLTE growth for the North American region. The report includes conclusions and recommendations for network operators.
