Optional Extras

Radio Frequency (RF) Survey Module

CSAS (Cell Site Analysis Suite) is complimented by the specialist Radio Frequency (RF) Survey Module. This is the only tool currently available that comprehensively processes and maps the outputs from Radio Frequency Propagation Survey devices such as Nemo™, CSurv™ and Forensic Compass.™ The RF Survey Module defines the outputs by technology e.g 2G, GSM, 3G and 4G, and by Network. It processes and maps location, route and coverage surveys.

With RF Surveys now a critical part of crime scene preservation, the ability to correlate the cell site evidence (upon which an evidential proposition relies) with the cell site footprint at the time of the incident is considered best practice. The RF Survey Module provides increased efficiency and accuracy for radio survey engineers involved in cell site mapping for digital forensic crime scene preservation. RF Survey evidence can then be used in conjunction with mobile phone billing records (which contain details of the cells used to carry each call) in an attempt to determine the potential location of ‘subject’ mobile phones when particular calls were made.

CSAS Collaboration Server

Our software can also be supplemented with the CSAS Collaboration Server, which provides a central case backup and sharing facility and also supports the provision of concurrent or ‘floating’ licences, allowing members of the same team to share cases in a cost-effective way.
