Rohde & Schwarz Validates 5G NR Protocol Conformance Tests with R&S CMX500

September 9, 2019

Rohde & Schwarz has carried out 5G NR protocol conformance testing with the new R&S CMX500 radio communication tester. Global Certification Forum GCF has accepted these 41 test cases, defined by 3GPP, in different FR1 and LTE band combinations. By adding the R&S CMX500 to their existing LTE test setups, accredited test houses, cell phone and chipset manufacturers get a smooth upgrade path from LTE to 5G NR testing.

The 5G NR protocol conformance tests were presented at GCF’s Conformance Agreement Group (CAG) meeting 59. These tests are vital for next generation mobile communication technology. This is because mobile network operators worldwide rely on the certification schemes of the GCF and PTCRB certification forum for mobile devices in their networks.

Rohde & Schwarz has been a one-stop solutions supplier for conformance and operator acceptance testing from 2G through LTE. The new R&S CMX500 adds 5G NR signaling 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 R&S CMX500 can be seamlessly integrated into existing LTE test environments, yet it is also ideal for 5G NR testing in standalone (SA) mode. Consequently, users who already have the well-established R&S CMW500 wideband radio communication tester or R&S CMWflexx test system can continue to use them for LTE measurements. To perform tests on 5G NR signals, they only need an R&S CMX500 as an extension box.
