Oppo Tests Voice and Video Calls on 5G Network

OPPO has announced today announced that they have successfully conducted voice and video calls solely based on the next-generation 5G network.

Partnering with Ericsson and MediaTek, the VoNR (Voice/Video on New Radio) calls were made on a modified smartphone from OPPO featuring MediaTek’s Dimensity 1000 series SoC using an end-to-end 5G Standalone (SA) network powered by Ericsson Radio System products and solutions as stated by Oppo in its press statement. The successful joint test was carried out under the 5G SA network environment provided by Ericsson at its headquarters in Stockholm, Sweden. After dialing, the two phones connected almost instantly and then seamlessly switched to a high-definition video call with a single keypress.

VoNR is a basic call service that completely relies on the 5G network (SA architecture). Compared with earlier call services, VoNR provides significantly lower latency, greatly improved sound quality and picture quality, resulting in an elevated overall experience for users as further explained by OPPO.

As one of the first mobile phone brands to support VoNR calls under the SA architecture, OPPO aims to ensure that even the early adopters can have a more complete 5G experience.

It also positions OPPO as the mobile phone partner of choice for operators and communication equipment suppliers building 5G networks around the world as the next generation of communication technologies demands a much higher technology capability from smartphone makers.

Andy Wu, Vice President and President of Software Engineering Business Unit, OPPO said, “As a leading global technology company, OPPO proactively works to accelerate large-scale commercialization of 5G. Our cooperation with Ericsson and MediaTek on VoNR is part of our in-depth collaborations in the 5G era. We aim to become the industry’s ideal partner to deploy 5G around the world and at the same time improve 5G experience for the users.”
