A Radio Frequency (RF) survey records the mobile network and Wi-Fi signals available at a specific location such as a scene, home address or alibi, or along a route relevant to your investigation. When combined with CDR analysis, the results help strengthen the cell site geolocation evidence in a case. TSG combines the use of advanced RF survey equipment (both SDR & SIM based) with experienced forensic practitioners to deliver high-integrity RF surveys to ensure our data is evidentially robust, court-admissible and conducted to FSR code standards.
