Voice over LTE (VoLTE)

Voice over LTE (VoLTE) can help you fulfil the vision of mobile broadband over LTE, ensuring profitable high quality voice, video and multimedia service to your customers.

Data may dominate mobile traffic, but voice and SMS still represent more than 70% of operator revenue and are the most used mobile services.

As consumers expect and demand more services for less money, it’s critically important to reduce delivery costs if service providers are to remain profitable. The flexibility and greater spectrum efficiency of Long Term Evolution (LTE) networks provides part of the answer.

But LTE network architecture doesn’t include traditional 2G/3G voice services. Operators are now faced with the need to move beyond data only LTE, the basis for LTE deployments, and migrate voice and messaging traffic to LTE networks.

With VoLTE, you get the capability to provide voice and SMS alongside LTE mobile broadband in a profitable, reliable way, uniting legacy networks with the new mobile technology.
