Enhancing Physical Perimeter Defense Using SDR
summary
Prototype uses a bladeRF to run a short‑range fake GSM BTS that forces phones to 2G, powers up intermittently (uploader notes 30s on/30m off; demo cycles 5–10m), and logs IMSI/TMSI along with timestamps and RSSI to encrypted storage. Software clusters repeated arrivals (neighbors), time‑only visits (deliveries/commuters) and one‑off unknown devices to flag reconnaissance; post‑breach correlates logged IMSIs with intrusion events. Tests are simulation data; FCC/legal limits and coarse location from RSSI remain key constraints.
