📞 VoNR (Voice over New Radio): Revolutionizing 5G Voice Calls


🔍 Introduction

With the evolution of 5G networks, traditional voice services are transitioning to VoNR (Voice over New Radio), which delivers high-quality, low-latency voice calls over 5G standalone (SA) networks. Unlike VoLTE (Voice over LTE), VoNR eliminates dependency on LTE, providing seamless end-to-end 5G voice services. Let’s explore how VoNR works, its interfaces, and its real-world impact! 🚀
