Huawei recently completed the world's first 5G VoNR call in China. 5G enhanced technology R&D test organized by the IMT-2020 (5G) promotion group, which marks the maturity of the 5G industry chain.
It is reported that the call is based on the 5G network built by Huawei. The two Mate 20X (5G version) mobile phones are located at two test sites in Beijing and Huairou, respectively, at least 60 kilometers apart, and the test distance is close to the commercial real scene. During the test, the two mobile phones made multiple voices and video calls, the connection rate was 100%, and the voice call voice was clear, which means that the VoNR call test under the world's first 5G SA network was successful.
