Validating The Non-Terrestrial Future

👉 Download the whitepaper, Validating the Non-Terrestrial Future: The Telco’s Strategy for 5G NTN Quality Assurance & Risk Management, to explore the full research insights. https://abi.link/lasting-1 In this ABI Research Snapshot, Andrew Cavalier is joined by Arpod Iozsa from LASTING Software to discuss how non-terrestrial networks (NTNs) are becoming a standard component of 5G—and why legacy testing approaches are no longer sufficient. With 3GPP Releases 17 and 18 integrating satellite connectivity directly into the radio access network (RAN), NTN performance is now judged against the same KPIs as terrestrial infrastructure, including latency, reliability, and service continuity. This shift raises the stakes for operators, as satellite impairments can now directly impact the end-user experience. Drawing on insights from ABI Research’s latest whitepaper, the discussion explores the operational and technical challenges of validating NTN environments—including extreme Doppler dynamics, rapid handovers, scalability constraints, and the “black box” risk of relying entirely on satellite partners. The conversation also highlights why software-defined channel emulation is emerging as a practical path forward, enabling scalable, cost-effective, and continuous NTN validation aligned with evolving standards and constellation architectures. Key topics include: • NTN integration into the 5G RAN under 3GPP Releases 17 and 18 • Doppler shift and rapid handover validation challenges • Independent testing to mitigate “black box” partner risk • Scalability limitations of legacy hardware-based RF emulation • Software-defined channel emulation for continuous NTN QA ABI Research ABI Research is a global technology intelligence firm uniquely positioned at the intersection of technology solution providers and end-market companies.
