Yes, phone call services in 5G can operate without the internet, thanks to the inclusion of voice services in the 5G network infrastructure.
Voice Services in 5G:
In summary, 5G can support voice calls through native 5G technologies like VoNR or by falling back to existing 4G networks, without needing an internet connection.
Yes, 5G networks can support phone call services independently of the internet through a technology called Voice over New Radio (VoNR). VoNR allows voice calls to be made using the 5G network’s infrastructure without needing to rely on traditional circuit-switched networks (2G/3G) or fallback to older technologies like VoLTE (Voice over LTE).
Here’s how it works:
1. Native Integration: 5G networks are designed to handle voice and data services simultaneously over the same network architecture, unlike previous generations where voice calls required separate infrastructure.
2. Efficiency and Quality: VoNR leverages the efficiency and speed of 5G, providing high-quality voice calls with faster call setup times and improved voice clarity compared to older technologies.
3. Coverage and Compatibility: As 5G networks expand, VoNR ensures that voice services can seamlessly transition between different generations of mobile networks (2G, 3G, 4G, and 5G) without disruption.
4. Standards Compliance: VoNR is based on global 3GPP standards, ensuring interoperability between different network operators and handset manufacturers.
5. Enhanced Features: 5G networks also enable the potential for enhanced voice services, such as higher-definition audio, simultaneous voice and data, and integration with advanced communication technologies like Internet of Things (IoT) devices.
Overall, VoNR in 5G networks represents a significant advancement in mobile communications, offering robust voice services without the need for traditional circuit-switched networks or reliance on internet connectivity.
As of last update, which was in early 2022, 5G technology primarily enhances internet connectivity rather than tradition
al voice calls. However, some mobile networks have integrated Voice over 5G (Vo5G or VoNR) for voice calls, but this generally requires internet connectivity.
For standard voice calls on a 5G network, the technology may fall back to 4G or even 3G networks, as these are optimized for voice communication. Therefore, while 5G can facilitate voice calls through its network, it still relies on underlying internet protocols for initiating and maintaining calls.
