Jio tests interoperability between 5G VoNR and 4G VoLTE

5G services have still not been launched in India and telcos have been testing 5G services for some time now. In a boost to its capabilities, Mukesh Ambani-led Reliance Jio has started testing the interoperability between 5G Voice over New Radio (VoNR) and 4G Voice over Long Term Evolution (VoLTE).

According to a LinkedIn post by Aayush Bhatnagar, senior vice president, Reliance Jio, the company has upgraded its 4G VoLTE network and has integrated its 5G core. This has enabled the company to test the interoperability between 5G VoNR and 4G VoLTE.

What is 5G VoNR?
5G VoNR removes the need for an LTE anchor that is used in 4G VoLTE, allowing the calls placed to stay on the 5G network. This ensures improved voice quality and high-definition audio.

In simpler words, with 5G VoNR allows calls to benefit from the lower latency that 5G networks offer, while also improving the sound quality. This technology will prevent the need to fall back to 4G for voice calls – telecom companies currently switch to 4G, 3G or even 2G networks for voice calls on their 5G networks.

In short, VoNR is to 5G what VoLTE is to 4G.

Why is 5G VoNR important?
As explained above, 5G VoNR allows you to enjoy the benefits of a 5G network to its full extent. VoNR support also allows you to enjoy calls over the 5G network while also enjoying the much faster data speeds that a 5G network offers.

Imagine the early days of 4G in India – especially on Reliance Jio – when you had to use the JioVoice app to make calls over Jio’s network, especially if your smartphone did not offer full 4G support over the Jio 4G network. Business Insider
