2966 rows (2965 geo-tagged) of CDR. Sheet named with subject A#. Fields: IMEI, IMSI, A#, B#, start/end timestamps, call type, direction, location string, cell ID, sector ID, lat/lon, duration.
Each (cell_id, sector_id) maps to a cell-tower GPS coordinate reported by the operator. Cell-tower centroid aggregated across multiple events gives a stable tower location. Single-cell reports 300m–3km in dense urban Karachi; multi-cell aggregation can reach 50–200m.
Per-day trajectories: collapse consecutive same-cell events into "dwells"; sum haversine distance between consecutive distinct cells. Flag long-distance events (>3 km) and trip days (>30 km).
196 unique B-numbers ranked by event frequency. Network classified by carrier prefix (300-309 Ufone, 310-319 Mobilink, 320-329 Warid, 330-339 Zong, 340-349 Telenor). Call patterns scored: in/out ratio, hour-of-day peaks, weekday weights, avg/max call duration.
Cell IDs grouped by physical tower — many "different" cell IDs share a tower at the same coordinates (multiple sectors, multiple operators co-located). OpenCellID API requires authentication token — not present in this environment.
