What is meant by VoLTE?
VoLTE is an abbreviation for Voice over Long Term Evolution. It is a voice over internet protocol or IP-based LTE network. It enables the users to make voice calls over LTE.
VoLTE allows High Definition (HD) voice calling. It is difficult to measure the quality of these calls, but they surely offer a noteworthy improvement over the conventional calls made via cellular networks.

Theoretically, LTE should offer data speeds that are capable of reaching 100-150 megabits per second while in motion, and 1GB per second when still.
How VoLTE works?
In “Voice over LTE” scenario, voice calls will be typically provisioned over a 4G LTE data network and not on the circuit-switched 2G or 3G networks that are normally used.
The VoLTE technology allows the voice to become another app that uses LTE data network. LTE, which is also known as Long-term evolution is the technology standard for delivering high-speed broadband services, that are commonly known as 4G.
VoLTE depends on the IP Multimedia Subsystem (IMS) network.
Benefits of VoLTE
It permits an operator to offer both, voice and data without switching between bands and treats voice just as another application that rides on an LTE data network.

The execution of VoLTE is beneficial in terms of both: cost as well as operation. We are provided with a more efficient use of spectrum than the traditional voice. It helps to meet the rising demand for richer and more reliable services.
VoLTE can be positioned in parallel with video calls over LTE and RCS multimedia services which include video share, multimedia messaging, chat and file transfer.
