Rohde & Schwarz validates first 5G RRM conformance tests
The Global Certification Forum GCF and the PTCRB certification organization have accepted first test case validations in various FR1 and LTE band combinations using the latest TS RRM 5G conformance test system from Rohde & Schwarz.

Mobile communication technology requires conformance tests since mobile network operators worldwide rely on the certification schemes of GCF and PTCRB for mobile devices in their networks. The updated version of the TS RRM has gone through this certification process, ensuring that the system is suitable for the 5G radio resource management (RRM) requirements defined in the 3GPP specifications and is now certified by GCF as platform 296.

RRM testing, as required by GCF and PTCRB, is a combination of several protocol and RF test methods. It is used to determine the reaction time of a cellphone to a changing RF signal and the time it takes for the device to switch to different signal sources.

The updated version of the TS RRM now features also 5G NR signaling functionality, thanks to the inclusion of the new CMX500 radio communication tester. As a result, the system now offers coverage for LTE, WCDMA, and 5G technologies. The integrated test system, operated by the sequencer software CONTEST, offers highly efficient and precise, reproducible measurement results.

A unique feature of the TS RRM is that it offers a smooth upgrade path to 5G for users with a previous version of the well-established TS RRM. The upgrade to 5G RRM testing can be achieved simply by adding the new CMX500 as an extension box.

These RRM test cases are also supported by TS8980, the RF conformance test system in the market supporting mobile technologies all the way from 2G to 5G on one platform.
