The convergence of satellite and terrestrial wireless networks is shifting the industry standard from LTE-based direct-to-device services toward New Radio Non-Terrestrial Network (NR-NTN) protocols. To address this transition, Korea Testing Laboratory (KTL) has selected Keysight Technologies’ NR-NTN radio frequency (RF) and Radio Resource Management (RRM) test solutions. This move aims to expand KTL's acceptance testing capabilities for next-generation satellite communications, supporting the validation of devices and networks before commercial deployment.
KTL Expands Satellite Validation Capabilities
KTL is positioning this infrastructure upgrade to extend its mobile communication testing expertise—spanning from 2G to 5G—into the satellite communication sector. By integrating Keysight’s Wireless Network Emulation Solutions, KTL intends to bolster its wireless validation portfolio with both pre-conformance and certification capabilities. This expansion is designed to help device manufacturers, chipset vendors, and network operators confirm performance and interoperability. As NR-NTN standards move from the specification phase into active implementation, KTL is attempting to provide the necessary testing environment to reduce deployment risks for satellite-enabled 5G services.
Keysight NR-NTN Test Solution Integration
Keysight’s contribution centers on its validated NR-NTN test case coverage, which has recently received Global Certification Forum (GCF) approvals. These solutions provide RF and RRM testing, which are critical for verifying how devices manage resources in non-terrestrial environments. The company is leveraging its existing experience in LTE direct-to-device testing and its expanded validation coverage under Third Generation Partnership Project (3GPP) and GCF programs. By providing these tools, Keysight aims to simplify how laboratories adopt new technologies, potentially improving operational efficiency and accelerating the readiness of the broader satellite-enabled ecosystem.
Key Takeaways
- KTL selected Keysight’s NR-NTN RF and RRM test solutions to expand its acceptance testing for satellite communications.
- Keysight's NR-NTN test case coverage has received recent Global Certification Forum (GCF) approvals.
- The transition to NR-NTN is expected to support broader device categories and higher-performance use cases compared to LTE-based services.
TechInsyte's Take
In our view, this partnership signals a critical shift in the telecommunications testing landscape as satellite connectivity moves from niche applications to mainstream 5G integration. By securing GCF-approved tools, KTL is effectively building a gateway for manufacturers to navigate the complexities of NR-NTN. This development suggests that the industry is prioritizing standardized, rigorous validation to manage the technical risks inherent in merging space-based and terrestrial networks. For enterprise leaders, this represents a foundational step toward more reliable, ubiquitous satellite-enabled mobile services.
