What Is 5GVoice andWhy Does It Matter? The IP multimedia system (IMS)- based phone calling service voice over 5G (Vo5G) or voice over new radio (VoNR) uses the 5G network as its source of internet protocol voice processing. The 5G radio access technology, which is an upgraded and updated version of the 4G radio access technology, is used for new radio network communication. There will be two types of voice services available via 5G mobile networks: • Carrier-grade voice service, which is not part of the public internet voice over new radio (VoNR) or Vo5G networks and has tight quality of service support. • OTT voice services will continue to exist in 5G networks and will be delivered via mobile internet access based on the best-effort principle and network neutrality (e.g., Viber, WhatsApp, Skype and others). Is 5GVoice Important? The demand for faster data speeds and innovative services is driving the development of 5G. However, the voice is significant for these reasons: 1. Smartphones with 5G data rates. 2. New 5G-specific use cases are supported. 3. The phase-out of the legacy system. What Happens to VoNR in the End? The 3rd Generation Partnership Project (3GPP) has stated 5G will utilize the 4G voice/video communication architecture while also providing IMS-based voice/video communication services. It’s worth noting that VoLTE and VoNR are two different access modalities for the IMS voice/video communication services. 5G Voice will make use of the existing network infrastructure IMS, which is being used to deliver voice over LTE services on LTE handsets today. As a result, for a 5G smartphone to make voice calls, the service provider must have enabled voice over LTE. Furthermore, it will take some time for 5G to be implemented fully across the entire network. In the interim, current 4G networks must be interworked with. From the perspective of the end user, the phone service is the same whether the connection is 4G or 5G. Even when switching from 4G to 5G, end consumers want smooth service continuity. Aside from making high-quality phone calls on 5G smartphones, what else would 5G Voice enable? In order for all of the other new and cooler 5G features to be made available, voice must work. 5G pioneers are researching and developing a variety of ideas and specific implementations for how 5G might provide a more beneficial user experience to consumers and business users — as well as industries and other use cases. According to Reports and Data, the voice over 5G (Vo5G) market will register significant growth over the coming years as voice communication demand increases. The consumer perspective Consumers can purchase a 5G smartphone with ultra-fast 5G speeds and low latency. They’ll be able to make high-quality, dependable phone calls, as they do on 4G and 2G/3G networks now. A new voice codec is something new (tech name EVS, evolved voice service, 3GPP standardized). This technology is being used in voice over LTE networks. It will, nevertheless, be the default voice codec in 5G. This means any user who purchases a 5G smartphone will have it pre-installed. It will offer a better voice quality experience than high-definition voice does now. Today, some service providers use the GSMA trademark “HD voice Plus” to sell this in LTE networks. Another unique feature of this voice codec is that it improves the quality of music shared over a voice call when compared to HD voice. o Paroma Bhattacharya is a content writer who has written pieces in health care, technology banking and a range of other industry verticals.
