Albany, NY -- (SBWIRE) -- 04/07/2016 -- VoLTE (Voice over LTE) technology allows a voice call to be placed over an LTE network, enabling operators to reduce reliance on legacy circuit-switched networks. Powered by IMS (IP Multimedia Subsystem) architecture, VoLTE brings a host of benefits to mobile operators ranging from the ability to refarm legacy 2G and 3G spectrum to offering their subscribers a differentiated service experience through capabilities such as HD voice and video telephony.

First deployed by South Korean operators in 2012, VoLTE is beginning to gain momentum globally. As of Q3'2015, more than 20 operators have commercially launched VoLTE services and several roaming and interoperability agreements are already in place.

Research estimates that VoLTE service revenue will grow at a CAGR of 36% between 2015 and 2020. By the end of 2020, VoLTE subscribers will account for nearly $120 Billion in revenue. Although traditional voice services will constitute a major proportion of this figure, over 12% of the revenue will be driven by video calling and supplementary services.
