A non-standalone 5G NR FR1 signalling test has been performed by Rohde & Schwarz and OPPO. The OPPO 5G smartphone was 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 the R&S CMX500 5G NR signalling tester from Rohde & Schwarz.
The R&S CMX500-based test setup provides a 5G network simulation to test a mobile phone in real-time using a signaling connection. This connection was used during the test to verify the protocol stack implementation of the OPPO mobile phone.
In addition, the test setup has LTE-Advanced-Pro features, such as the support of five-component carrier (5CC) and 4x4 MIMO.
It can also 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 radio communications 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, said: "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."
