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.

Key Findings:

The report has the following key findings

By 2020, SNS Research estimates that VoLTE services will account for nearly $120 Billion in annual service revenue, as mobile operators remain committed to VoLTE as the long term solution to secure a fully native IP based telephony experience

Nearly all VoLTE operators are committed to migrate existing mobile voice subscribers to LTE in order to refarm their 2G and 3G spectrum

Some operators are integrating their VoLTE services with WiFi calling in a bid to offer voice services in areas where their licensed spectrum coverage is limited

SNS Research estimates that VoLTE capable smartphone shipments will grow at a CAGR of 33% between 2015 and 2020, eventually accounting for over 950 Million unit shipments by the end of 2020

As part of the wider NFV (Network Functions Virtualization) initiative, many vendors are integrating their virtualized VoLTE offerings with cloud platforms

The vendor ecosystem is gradually consolidating with several prominent acquisitions such as Mitel’s acquisition of VoLTE specialist Mavenir Systems
