🎯 Learning Outcome: This lab visualizes how different payload architectures affect protocol termination points. Transparent: gNB on ground, satellite is RF repeater. Regenerative (gNB): Full gNB on satellite. Regenerative (gNB‑DU): Split architecture with DU on satellite, CU on ground. Click on NR‑Uu, F1, or NG to see the protocol stack mapping.
