Implication

This study investigates 5G non-terrestrial network architectures, using satellite mega-constellations to evaluate user experience metrics and performance challenges.

Key Points

Results show that backhaul and midhaul relays maintain delays of 50–60 ms under transparent architectures.
Round-trip time and jitter are assessed using OpenAirInterface and Open5GS to monitor user-plane performance.
Integration of transparent architectures highlights significant delays in NR signals exceeding one second due to traffic overload.
While transparent architectures offer insights, regenerative architectures are crucial for optimizing space-based broadband capabilities.
