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.Caption: At the core of NR-NTN conformance test solutions: the CMX500 OBT.
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 (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).
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 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 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 an intuitive tool for visualizing satellite constellations – all in a single-box test setup. In addition, the user-friendly R&S CONTEST test system software platform facilitates the seamless execution of 3GPP test cases.
