Oppo has completed voice and video calls based solely on a next generation 5G network.

The successful tests were made on a modified commercial smartphone from Oppo using MediaTek’s Dimesnity 1000 series system-on-chip using end-to-end 5G standalone network powered by Ericsson’s radio systems products.

Voice/Video on New Radio (VoNR) is a call service that relies on standalone architecture, which is key for future 5G networks. Standalone networks only use 5G whereas non-standalone networks use 4G base stations and technology to run 5G signals on, which doesn’t have the same amount of networking power as standalone networks.

The joint tests were carried out under the 5G SA network environment provided by Ericsson at its headquarters in Stockholm, Sweden. After dialing, two phones were connected almost instantly and then switched to a high-definition video call with a single keypress.

Oppo claims it is one of the first technology brands to support VoNR calls under the SA architecture and will lay a foundation for operators and communication equipment suppliers to build 5G networks worldwide.

"After spearheading 5G rollouts across the world, we are gearing up for the next step: 5G Standalone services,” said Hannes Ekström, head of product line 5G RAN at Ericsson. “Using an Ericsson end-to-end 5G Standalone network based on commercial hardware and software, along with devices from our partners Oppo and MediaTek; we've shown that beyond the high-speed capabilities delivered by 5G. We are ready to deliver on the voice and video calls that will remain important to consumers."
