OPPO successfully completes 5G signalling and data links using commercially available smartphones.
OPPO 5G testing
OPPO recently announced that they have successfully completed the 5G signal tests using commercially available smartphones in Shenzhen, China. The company used a phone based on the OPPO R15 integrated with a Qualcomm Snapdragon X50 5G modem to do the testing.
According to Liu Chang, Director of OPPO Research Institute, access to the signalling and data links is the basis for reliable communications functions of 5G mobile phones. Using commercially available smartphones to access 5G connectivity will speed up development of 5G smartphones, and in turn will result in available 5G products in 2019.

The breakthrough in signalling and data connectivity was based on the 3GPP Release 15 NSA standard, using the 10 MHz bandwidth in 4G LTE Band 5 and the 20 MHz bandwidth in 5G NR n78. The n78 band is one of the most widely used 5G NR frequency band in the world, and is also considered to be the most likely band for priority deployment worldwide.
Last May, OPPO successfully complete the world’s first 5G video call using 3D structured light. Peak transmission rates with a downlink of 1.4 Gbps and an uplink of 160 Mbps were reached. Because of this, the company won first prize in the “Blooming Cup” 5G Application Contest sponsored by the Ministry of Industry and Information Technology, China Information and Communication Research Institute and the IMT-2020 (5G) Promotion Group.
