Rohde & Schwarz, in partnership with Chinese electronics manufacturing company, OPPO, has performed a non-standalone 5G NR FR1 signaling test. The OPPO 5G smartphone used in the test was powered by the Qualcomm Snapdragon X50 5G modem and RF front-end solutions. The test was carried out using an R&S CMW500 wideband radio communication tester and the new R&S CMX500 5G NR signaling tester.
The 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 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 radio communications technologies.
OPPO and Rohde & Schwarz have been working together on the development and production of mobile phones for a long time. They plan to continue working together in the 5G era to bring better communication experiences to users.
