Every time a person uses their handset to make or receive a call or text message, or access the internet, data is stored by the network – including a record of which mast provided the coverage needed, thereby revealing the approximate location of the phone at that time.
Call data record analysis
Each item of data stored is known as a call data record (CDR). Our experts can use this data, along with extensive radio frequency measurements, to produce detailed reports on the likely positioning and movements of a mobile phone. These reports can be used as evidence to back up or disprove statements relating to an investigation.
