Oppo announced today that it has 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 commercial smartphone from OPPO featuring MediaTek’s Dimensity 1000L SoC in a 5G SA (standalone) network environment made possible by Ericsson.
VoNR is a basic call service that completely relies on the 5G network (SA architecture). Compared with earlier call services, VoNR enjoys lower latency, improved sound quality and picture quality. SA architecture is one of the mainstream architectures of future 5G networks.
Andy Wu, vice president and president of Oppo’s Software Engineering Business Unit, said, “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. “
The 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 quickly and switched to a high-definition video call with a single keypress.
