Successful validation of 5G NR cellular sub 6GHz signalling tests has been achieved by Rohde & Schwarz and Qualcomm Technologies. It brings the commercial roll-out of 5G NR one step closer. The end-to-end tests were done using the new R&S CMX500 radio communication tester, which will debut at Mobile World Congress 2019 in Barcelona (February 25-28).

With this new test platform along with the R&S CMP200 and R&S CMW100, Rohde & Schwarz is completing its portfolio for standard compliant device tests for 5G NR.

The test device was verified under signalling conditions compliant to 3GPP Standard (Release15) in Non-Stand Alone (NSA) mode. This effort between Rohde & Schwarz and Qualcomm Technologies paves the way to get 5G New Radio technology ready for commercialisation.

Rohde & Schwarz has been supplying future-proof test and measurement solutions to the wireless industry since the development the GSM system simulator all the way to current cellular communications technologies such as LTE-Advanced Pro.

For the fast emerging 5G standard, Rohde & Schwarz has rounded out its portfolio: For signalling tests, the 5G NR signalling tester R&S CMX500 is combined with the R&S CMW500 wideband radio communication tester.

In addition to the protocol testing during the R&D phase, the solution can also be used for calibration and non-signalling tests and also supports the test of the related LTE-A features, such as 5CC and 4x4 MIMO.

For non-signalling tests, the R&S CMW100 communication tester covers testing in development, evaluation, verification, calibration and manufacturing for 5G NR FR1. Rohde & Schwarz has developed the R&S CMP200 radio communication tester for verification and calibration of 5G NR FR2 in the mmWave range.

This non-signalling one-box tester addresses efficient high-volume RF parametric testing in R&D and manufacturing. These up-to-date solutions enables customers to fulfil their 5G requirements in the chipset, smartphones, tablets industry for reliable, efficient and scalable testing.
