Engineers from six OPPO research and development institutes worldwide participated in the video call, the company said on Monday.


The video call was made on an OPPO R15 Pro-based 5G smartphone and lasted for more than 17 minutes on a 5G network with a bandwidth of 100 (megahertz) MHz.


Engineers operating out of OPPO`s six R&D institutes worldwide reported smooth connectivity and low latency during the video call.


For the 5G test, OPPO said it used Keysight`s UXM signalling test set and 5G New Radio (NR) network emulation solutions for protocol and radio frequency (RF) performance validation in sub-6 gigahertz frequency bands.


OPPO completed its first 5G signalling and data connections on a smartphone in August and became the first company to complete a 5G Internet access test on a smartphone in October.


The Chinese smartphone maker said it was working towards becoming the first brand to release real commercial 5G smartphones next year.
