5G signalling test conducted by Rohde & Schwarz and OPPO

Test and measurement expert Rohde & Schwarz and electronics manufacturer OPPO have performed a non-standalone 5G NR FR1 signalling test, with a OPPO 5G smartphone powered by the Qualcomm Snapdragon X50 5G modem and RF frontend solutions. The test was carried out using an R&S CMW500 wideband radio communication tester and R&S CMX500 5G NR signalling tester from Rohde & Schwarz.

The R&S CMX500-based test set-up provides a 5G network simulation to test a mobile phone in real time using a signalling connection. This connection was used during the test to verify the protocol stack implementation of the OPPO mobile phone. In addition, the R&S CMW500 adds LTE-Advanced-Pro features, such as the support of five-component carrier (5CC) and 4x4 MIMO.

The test system can simultaneously support other cellular and non-cellular technologies, such as 2G, 3G, NB-IoT Release 14, C-V2X, 802.11ax and Bluetooth v5.0, to fully meet the development requirements for multiple modes of radiocommunications technologies.

Xu Ming, responsible for product development system at OPPO VP, said, “OPPO and Rohde & Schwarz have a long-term and in-depth cooperation in the development and production of mobile phones. This cooperation has played a very important role in improving the communication experience with OPPO devices. We hope that we work hand in hand with Rohde & Schwarz in the 5G era to bring a better communication experience to users.”

Anton Messmer, Vice President Mobile Radio Testers at Rohde & Schwarz, added, “We are very happy for having carried out a successful 5G NR signalling test with OPPO. This event marks a new milestone, inspiring further development of 5G test cases with OPPO and other valued partners in the industry.”
