Why Is Channel Emulation Key For Deploying 5G Non-Terrestrial Networks Successfully?

5G Non-Terrestrial Networks (NTN) enhance connectivity by integrating airborne and space-based platforms, overcoming the limitations of traditional ground-based infrastructure. These platforms include satellites, high-altitude platforms (HAPS), and drones, each with unique capabilities.

Satellites are categorized by orbit: Low-Earth Orbit (LEO) satellites provide low-latency, high-speed data but require frequent handovers due to limited coverage; Medium-Earth Orbit (MEO) satellites balance latency, coverage, and performance; and Geostationary Orbit (GEO) satellites offer wide coverage but experience high latency and signal loss. HAPS, such as stratospheric balloons or solar-powered systems, deliver extended 5G coverage, while drones enable dynamic, quick-deployment solutions in localized scenarios.

Channel emulation plays a crucial role in ensuring NTN performance. Non-terrestrial networks face unique challenges, including significant time delays, Doppler shifts, and atmospheric effects, which terrestrial networks typically do not encounter. Advanced channel emulators, like the Maury Microwave ACE9600, simulate these real-world conditions in a controlled environment. The ACE9600 supports dynamic impairments such as phase-continuous time delays, Doppler shifts, and atmospheric effects like path loss and scintillation.

Emulation tools are vital for pre-deployment testing, as NTN repair and servicing are often impractical. The ACE9600 also incorporates hardware-in-the-loop testing to evaluate hardware-induced distortions, ensuring comprehensive system performance analysis.
