Description

Vo5G, or Voice over 5G, refers to the voice and video communication services enabled by the 5G mobile systems. While 5G's evolution is primarily driven by data services, voice and video communication remain crucial for its success.In the initial phase of 5G deployment, voice and video services are delivered over LTE networks using the IMS (IP Multimedia Subsystem) platform. This technology is known as VOLTE (Voice Over LTE) in 5G non-standalone deployment. As 5G advances, the focus shifts to the new 5G radio access technology,  known as NR (New Radio), which enables VoNR (Voice over New Radio) as the next-generation solution for delivering voice and video services.. VoLTE and VoNR represent different access modes for delivering IMS-based voice and video communication services.The transition from VoLTE to VoNR marks the evolution of Vo5G, which goes beyond traditional calls. With Vo5G, improved voice and video services will integrate seamlessly into a variety of 5G-enabled applications, such as augmented reality (AR), remote robotics, and immersive entertainment platforms like gaming and streaming.This course delves deep into the technical intricacies of Vo5G, providing a comprehensive understanding of how voice and video services are evolving alongside 5G technology.
