Cell site analysis is a service which is performed to find the location of a smartphone at certain moment in the past. Raw data from CDR (Call Data Records) allows legal professionals to learn about the origin, duration, time, and date of a call. Each time two smartphones are interacting using voice calls or text messages, it is be recorded by the system. Each antenna or base station has a unique identifier within the cellular network, making it a straightforward process to locate a person who is using a tracked smartphone. Many smartphone users are making fewer voice calls and sending text messages, because email, social media, instant messaging, and voice calls are equally or more convenient to use. In this case, it is still possible to find out when the smartphone is initiating an Internet connection.
Cell Site Analysis For Law Enforcement Agencies
When law enforcement agencies are investigating whether a suspect committed a crime, cell site analysis is a useful and accurate method to verify location of suspects. As long as the smartphone remained active and connected to the cellular network, they can verify the location of suspects at the exact time when the crime was committed. Whether it is homicide or theft, cell site analysis works well in criminal defence cases. It has proven invaluable for pursuing a fair trial. Depending on certain factors, cell site analysis may uncover strong evidence to allow the justice system to determine who is responsible for the crime. It can protect someone who has become a scapegoat or is wrongly accused of committing a crime. It is also possible to uncover or dismantle a criminal network if various key individuals are identified and located using the cell site analysis.
Here are some of the ways cell site analysis can be useful in a criminal defence case:
Identify Time And Locations- cell site analysis is useful to determine the whereabouts of someone or a suspect at specific times in the past. As mentioned above, every base station or cell site in the network as unique identifier. Depending on the signal strength, the range of a base station is between 500 metres to 30 kilometres. Cell sites in urban areas are smaller to provide better coverage.
Specify What Was Communicated- whether it’s voice call, text message, or Internet-based messages, investigators can find out what the suspect sends or receives at specific time and location.
Track Movements- if the suspect is not yet apprehended, cell site analysis can track his/her movement at real time. Any detail gathered during the tracking process can be used later in criminal defence trial.
