Cellsite Forensic

Cell-site Forensic App enables forensic surveys of the cell-sites that provide coverage for a crime scene. It records the cell ID, frequencies and signal strength against the GPS location. Locations of interest can be marked and the Officer can track their progress during the survey. A working copy can be downloaded onto the phone. The survey results are saved as a hashed (Gold) copy to a trusted server for later retrieval.
