HEAD acoustics and Rohde & Schwarz Test Voice over 5G New Radio Communication Quality

Working together with Rohde & Schwarz, HEAD acoustics have created a test solution that was able to successfully verify the communication quality of 5G (VoNR)-capable devices. VoNR, or “Voice over 5G New Radio” is a call service which fully explores the capabilities in the SA architecture for 5G networks. Compared to other communication services, VoNR provides significantly lower latency and improved sound and picture quality, improving the calling experience.

audioXpress is proud to publish a contributed article by Manfred Lutzky, Head of Audio for Communications at Fraunhofer IIS, Audio and Media Technologies division and one of the members of the team responsible for the development of state-of-the-art speech and audio communication codecs such as EVS, AAC-ELD, and LC3/LC3plus. In this article, he provides a valuable perspective about the technologies and audio codecs that we depend upon to make audio and video conferencing calls. This article was originally published in audioXpress, October 2020.

At the Mobile World Congress 2016 in Barcelona, Rohde & Schwarz introduced new RF and audio multistandard test solutions for manufacturers of Bluetooth headsets and audio car kits, and added the enhanced VoLTE voice service codec to its R&S CMW500. The R&S CMW500 is the only test platform on the market to offer a one-instrument solution for testing all cellular and non-cellular standards and Bluetooth.
