Rohde & Schwarz, in cooperation with Samsung, is driving the commercialization of 5G-based non-terrestrial networks by successfully validating first NR-NTN test cases according to 3GPP Release 17 test specifications for RF, RRM and PCT. 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.

Rohde & Schwarz and Samsung are collaborating to bring 5G NR-NTN to market. Both companies 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 test specifications for RF (Radio Frequency), RRM (Radio Resource Management) and PCT (Protocol Conformance Testing) using conformance test solutions from Rohde & Schwarz.
The validated test cases, as defined by PTCRB 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 the device under test (DUT).
The Importance of NR-NTN Conformance Testing
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 terrestrial networks, due to:
-
Vastly different operating environments
-
Long signal propagation delays
-
Highly dynamic satellite orbits
-
Varied link conditions compared to ground-based systems
Industry Perspective
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 leading edge in conformance testing, providing its comprehensive solutions across all three domains. We’re proud to partner with industry leaders like Samsung who rely on our solutions to ensure device conformance, to enable tomorrow’s connectivity.”
At the Core: The CMX500 OBT
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
-
An intuitive tool for visualizing satellite constellations
-
A complete, single-box test setup
Additionally, the R&S CONTEST test system software platform enables seamless execution of 3GPP test cases across domains.
