Voice over LTE (VoLTE)
Search Networking, March 23rd, 2023
Voice over LTE, or VoLTE, is a digital packet technology that uses 4G LTE networks to route voice traffic and transmit data. This voice service is the standard for high-speed wireless communications in devices such as smartphones, data terminals, IoT devices and wearables.
VoLTE is important for network operators, vendors, original equipment manufacturers and consumers. Since LTE is a data-only networking technology, VoLTE provides higher quality calls, better service, and the ability to use voice and data simultaneously.
How does VoLTE work?
VoLTE is based on the IP Multimedia Subsystem framework. This enables the service to deliver multimedia as data flows using a common IP interface that can use but doesn't depend on a legacy circuit-switched voice network.
