Identify the Problem Interval  \n   - Locate rows in the drive-test data where throughput drops below the specified threshold (e.g., 600 Mbps).\n\n2. Identify the Serving Cell  \n   - Note the “5G KPI PCell RF Serving PCI” corresponding to the low-throughput interval.\n\n3. Locate the Cell  \n   - Find this PCI in the Engineering Parameters table and extract:\n     - Cell ID\n     - Longitude\n     - Latitude\n\n4. Calculate Distance (CRITICAL)  \n   - Calculate the geographic distance between:\n     - User GPS coordinates (from drive test)\n     - Serving Cell coordinates (from engineering parameters)\n   - Use the following approximation:\n     - 0.01° Latitude ≈ 1.11 km\n     - 0.01° Longitude ≈ 0.9 km (mid-latitudes)\n   - If the distance is greater than 1.0 km, this is a strong indicator of **Over-shooting (Cause C2)**.\n\n5. Evaluate Other Metrics  \n   - SINR: Low SINR may indicate over-shooting or interference.\n   - Speed: Check if UE speed is greater than 40 km/h.\n   - Neighbor PCIs: Check for Mod-30 PCI collisions or strong neighbors.\n\n6. Select Root Cause  \n   - Choose the single most likely root cause from the list (C1–C8).\n\nOutput Formatting Rules (MANDATORY):\n\n- You must analyze the problem step-by-step inside a hidden reasoning block:\n  <think>\n  ...your detailed reasoning steps...\n  </think>\n\n- After the reasoning block, provide a concise human-readable explanation.\n\n- End the response with the final answer code formatted exactly as:\n  <SOLUTION>{C#}</SOLUTION>\"\n' + eos_token }}{% set loop_messages = messages %}{% endif %}{% for message in loop_messages %}{% if message['role'] == 'user' %}{{ message['content'] }}{% elif message['role'] == 'assistant' %}{{ message['content'] + eos_token }}{% endif %}{% endfor %}{% if add_generation_prompt %}{{ '<think>' }}{% endif %}"
