What is Voice over Long-Term Evolution (VoLTE)?

Voice over long-term evolution is abbreviated by Voice over LTE or VoLTE. It refers to a technical specification that details the guidelines and procedures for transmitting speech and data over 4G LTE networks. One method for creating, offering, and maintaining high-speed phone, video, and message services for mobile and portable devices on a 4G wireless network is this one.

How Does Voice over Long-Term Evolution (VoLTE) Work?

VoLTE is built on the architecture of the IP Multimedia Subsystem (IMS). This makes it possible for the service to send multimedia as data flows across a single IP interface. Although, it can use a conventional circuit-switched voice network but is not reliant on it.

For instance, a user can start a call using the LTE network. The call will be returned to the legacy network if they depart an LTE coverage area. Single Radio Voice Call Continuity (SR-VCC) is a feature that enables two connections to be kept active simultaneously until the LTE signal is lost.

Furthermore, the suggested speech codec for VoLTE is adaptive multi-rate wideband (AMR-WB) or HD voice. HD speech enhances sound quality while expanding the audio frequency range for voice calls.

What are the Key Benefits of VoLTE (Voice over Long-Term Evolution)?

Enabling VoLTE provides numerous benefits in terms of cost and operations. Some of them are the following. So, let’s have a look at them!

1. It offers a more efficient use of the spectrum in comparison to the traditional voice.

2. Satisfies the growing need for "Richer," more reliable services.

3. The voice on one network and data on another is no longer required.

4. Voice over Long-Term Evolution uses IMS as the common service platform to open up new revenue opportunities.

5. It may be used with RCS multimedia services including video sharing, multimedia messaging, chat, and file transfer as well as video calls over LTE.

6. Battery life on smartphones has increased by 40%. (compared with VoIP)

7. It gives the experience of making calls very clearly

8. Voice over Long-Term Evolution (VoLTE) enables rapid call setup.
