Rohde & Schwarz validates 5G NR protocol conformance tests

Rohde & Schwarz has carried out 5G NR protocol conformance testing with the R&S CMX500 radio communication tester. The Global Certification Forum GCF has accepted these 41 test cases, defined by 3GPP, in different FR1 and LTE band combinations. Accredited test houses, cell phone and chipset manufacturers can add the CMX500 to existing LTE test set ups, to smoothly upgrade path from LTE to 5G NR testing.

Mobile network operators worldwide rely on the certification schemes of the GCF and PTCRB certification forum for mobile devices in their networks. The CMX500 adds 5G NR signalling and RF testing by measuring the RF parameters of 5G NR transmissions and performing protocol tests. As most network operators will implement 5G NR as an extension of an LTE mobile network, the CMX500 can be seamlessly integrated into existing LTE test environments. It is also ideal for 5G NR testing in standalone (SA) mode. Developers using the R&S CMW500 wideband radio communication tester or R&S CMWflexx test system can continue to use them for LTE measurements and add the CMX500 as an extension to perform tests on 5G NR signals.

The Rohde & Schwarz technology group develops, produces and markets communications, information and security products for professional users. The group’s test and measurement, broadcast and media, aerospace, defence, security, networks and cybersecurity business fields address many different industry and government-sector market segments.

The company has its headquarters in Munich, Germany. It subsidiaries in more than 70 countries, with regional hubs in Asia and America.
