Voice over New Radio (VoNR)
Commonly used in Telecommunications
Voice over New Radio (VoNR) is a technology that allows voice calls to be made over 5G networks, offering improved call quality and greater reliability compared to previous generations. It integrates voice services directly into the 5G infrastructure, enabling seamless communication alongside data services.
How It Works
VoNR operates by utilising the 5G New Radio (NR) interface, which is the radio access technology for 5G networks. It replaces traditional circuit-switched voice calls with packet-switched voice transmission, similar to Voice over IP (VoIP). The technology leverages the 5G core network to handle voice traffic, ensuring low latency and high-quality audio. Devices establish a dedicated session using the IP Multimedia Subsystem (IMS), which manages the signalling and media exchange for voice calls. This setup allows voice and data to share the same network infrastructure, simplifying operations and reducing latency.
Common Use Cases
- Making high-definition voice calls over 5G networks without dropping to 4G or Wi-Fi.
- Supporting simultaneous voice and high-speed data transfer on 5G-enabled smartphones.
- Enabling real-time voice communication for enterprise applications via 5G networks.
- Providing improved voice quality for emergency services using 5G connectivity.
- Integrating voice services into IoT devices that operate on 5G networks for better communication reliability.
Why It Matters
VoNR is a critical component of the 5G ecosystem, as it ensures that voice communication keeps pace with the high-speed data services that 5G offers. For IT professionals and network engineers, understanding VoNR is essential for deploying and managing next-generation networks that support both voice and data seamlessly. Certification candidates focusing on 5G technology need to grasp how VoNR integrates with the overall network architecture to optimise user experience and meet service quality standards. As voice remains a fundamental communication method, VoNR’s ability to deliver high-quality, reliable calls over 5G makes it a key enabler for future communication services and applications.
