- Rohde & Schwarz and Samsung have worked together to enable the validation of the first 5G-based New Radio non-terrestrial networks (NR-NTN) test cases in accordance with the 3GPP Release 17 test specifications for RF (Radio Frequency), RRM (Radio Resource Management) and PCT (Protocol Conformance Testing).
The validated test cases, as defined by PTCRB (PCS Type Certification Review Board) RFT 555 (Request for Testing), were conducted on the R&S TS8980 Conformance Test Platform, the R&S TS-RRM and the CMX500 in frequency range 1 (FR1) verifying Samsung’s latest NR-NTN chipset as device under test (DUT). This makes Rohde & Schwarz the first and only test and measurement provider to deliver validated coverage for 5G NR-NTN across all three test domains.
In preparation for the commercial rollout of a new mobile technology, 3GPP conformance testing is essential for ensuring that devices and networks comply with global standards. This is particularly true for 5G NR-NTN, set to bring reliable satellite-based connectivity to remote areas. However, NR-NTN testing presents challenges that extend beyond those encountered in traditional terrestrial networks, primarily due to the vastly different operating environment and the dynamic nature of satellite-based communication.
Goce Talaganov, Vice President of Mobile Radio Testers at Rohde & Schwarz, said: “Conformance testing – covering RF, RRM and PCT – is critical for a positive user experience and a stable mobile ecosystem. Rohde & Schwarz has consistently been providing its comprehensive solutions across all three domains.”
At the core of the Rohde & Schwarz conformance test solutions is the CMX500 5G one-box signaling tester, which also supports early research and development through integrated fading and channel emulation, along with a tool for visualizing satellite constellations – all in a single-box test setup. In addition, the R&S Contest test system software platform facilitates the seamless execution of 3GPP test cases.
