🎯 Learning Outcome: This lab demonstrates the handover rate challenge in LEO NTN networks.
📌 Key Insight: As the satellite moves at 7.56 km/s, all UEs in a cell must handover within Diameter / Speed seconds.
⚠️ Small Beam (50km) + 65,519 UEs → ~19,800 HO/s
🟡 Medium Beam (250km) + 1,000 UEs → ~600 HO/s
✅ Large Beam (1000km) + 100 UEs → ~100 HO/s
⚠️ Small Beam (50km) + 65,519 UEs → ~19,800 HO/s
🟡 Medium Beam (250km) + 1,000 UEs → ~600 HO/s
✅ Large Beam (1000km) + 100 UEs → ~100 HO/s
📊 Formula: Handover Rate = (UEs × 2 × Satellite Speed) / Beam Diameter
