As the world embraces the next-generation 5G wireless communications technology, the convention of making a call is set to change for good. Oppo has become one of the first companies to have conducted voice and video calls "solely" based on 5G. The Chinese company partnered Ericsson for the 5G network equipment while MediaTek provided its Dimensity 1000- series chipset for the test. It is called a VoNR call, short for Voice/Video over New Radio, and is relied on the SA architecture of 5G, eliminating the need for NSA mode that is bound to be phased out in future.

Oppo said it used a "modified commercial" smartphone, powered by the Dimensity 1000-series SoC, to conduct the VoNR call using end-to-end 5G SA network, provided by Ericsson. "As one of the first technology brands to support VoNR calls under the SA architecture, OPPO aims to ensure that even the early adopters can have a comprehensive 5G experience," said Oppo in a press statement. The test was carried out at the Ericsson headquarters in Stockholm, Sweden. The 5G SA network environment was provided by the network equipment making company at its headquarters.

With the recent piloting of the VoNR call, Oppo "aims to ensure that even the early adopters can have a comprehensive 5G experience." It is crucial for companies such as Oppo to spearhead the development and adoption of the next-generation technologies, especially when their fight against the bigwigs, such as Samsung and Apple, has intensified. This is largely also why Oppo files a number of patents to showcase its technologies and prototypes.

According to the press statement, Oppo has been ranked among the Top 5 Patent Cooperation Treaty (PCT) filers by the World Intellectual Property Organization (WIPO) for the year 2019, with a total of 1,927 applications so far. "In 2019, OPPO joined partners to take the lead in implementing the world's first video data call based on Dynamic Spectrum Sharing (DSS) technology," said Oppo.

"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, enhance 5G experience for the users," said Ethan Xue, President of OPPO Middle East and Africa.
