Cell Site Analysis
Cell Site Analysis At ValMIND
Cell Site Analysis is a branch of digital forensic science. This pertains to legal evidence found in computers and digital storage media. The goal of Cell Site Analysis is to examine digital media in a forensically sound manner with the aim of recovering, linking and understanding information.
Cell Site Analysis is a technique used to pinpoint the location of a mobile phone at a specific time, with accuracy reaching within a few meters. This type of evidence can be pivotal in determining the outcome of a case. By examining Extended Call Data Records and conducting Cell Site Analysis, our analysts can generate detailed reports that trace the likely positions and movements of mobile devices to within a few meters.
Our experts can collect and analyse cell site data to establish the whereabouts of an individual’ mobile phone at any given time or to track the mobile phone’s movements between locations. This information can be used as vital evidence during legal proceedings, not only to prove what the user of the phone did or where (s)he was, but more importantly where the person could not have been. Data collected via on-site surveys is presented in various colour coded map formats displaying the coverage area of specific cell sites.
What We Do
Law enforcement routinely analyzes cell site data to determine the location of a mobile device when it received or sent an SMS, made a call, or transferred data over the internet. The mobile phone's location will be within the range of the cell site that managed the communication.
The Process
- The process involves analyzing call data records from the service provider and, when necessary, conducting on-site radio frequency surveys. This includes examining measurements taken at the location of the serving cell site mast to determine coverage. Cell Site Analysis is used to identify which cells a mobile phone is likely to connect to, based on the characteristics and behavior of the mobile network at a specific geographical point or area of interest.
- A forensic cell site expert can correlate this information with the call data records from mobile networks to determine possible locations of a mobile phone during past connections.
- Using data from mobile phone service providers, our cell site experts measure actual coverage through sophisticated data gathering, positioning, and analytical tools. The information collected is used to create detailed coverage maps, with service areas of individual cell sites represented in different colors. These maps are available in various formats, including aerial photography, A-Z street maps, and OS ranges.
