Tata Communications to supply Voice over LTE calling

07 Feb 2014 Evaluate

Tata Communications will supply Voice over LTE calling (VoLTE) to its growing global community of IPX-connected service providers. VoLTE will allow mobile network operators to offer HD voice over their LTE / 4G networks and is seen as a key factor for the success of 4G customer uptake. Customers will benefit from near-instant call setup, better sound quality and the ability to have HD Voice conversations with more users outside the mobile-only community.

VoLTE is viewed as a critical next step in continuing to deliver a high quality voice experience. It offers customers HD Voice, while enabling mobile network operators to operate on the basis of an all-IP infrastructure. This is significant in that it produces operational efficiencies and the required foundation for deploying new services, as well as integration for further applications aimed at improving user experience.

For mobile network operators, the improved quality leads to increased usage, and ultimately, better revenues. Mobile voice quality issues are an ongoing concern for network operators and investing in VoLTE is set to greatly reduce customer churn and improve the customer experience. Analysts estimate that VoLTE services combined with OTT VoIP are set to become a $16 billion business by 2017.
