About Voice over 5G

  • It is also known as Voice over New Radio (VoNR).
  • This standard allows voice calls over 5G networks instead of the current standard that uses 4G.
  • In simple terms, Vo5G takes all the improvements of 5G – speed, capacity, responsiveness – and applies them squarely to voice.
  • It aims to have all that infrastructure and interoperability ready well in advance.
  • To use Vo5G, you need three things: a phone that supports Vo5G, a carrier that offers Vo5G, and a 5G signal in your area.

How is VoNR better than VoLTE?

  • VoNR brings clear advances over VoLTE.
  • With 5G’s substantially higher bandwidth and lower latency compared to 4G LTE.
  • Enhanced call quality: It utilizes more advanced audio codecs that provide superior clarity and fidelity based on 5G’s increased data capacity.
  • Faster connection times: It promises faster call connection times, ensuring a seamless and prompt user experience.
  • Improved reliability: Vo5G aims to eliminate the notorious call drop issues, particularly during transitions between 5G and 4G.
  • Lower packet loss contributes to better reliability, minimising the occurrence of voice cutouts during calls.
