Cell Site Analysis (CSA) is the science of reconstructing the physical movements of a mobile telephone or communication device.  The evidence produced from such advanced investigations can be especially powerful in attributing contact between individuals, proximity to a scene of crime, patterns of movement of suspects, and testing the strength of alibi evidence.

ACK-EVIDENCE provide independent and professional services for all aspects of Cell Site Analysis - whether examinations are historic in nature or concerning 'live' data/subjects'.

These services are for evidential purposes and are supported by the production of certified Statements / Expert Reports and attendance in court to provide clear testimony as Expert Witnesses.

"CSA Evidence - as useful as DNA or fingerprints"
From undermining the alibi of HUNTLEY in the SOHAM MURDERS, the attributing of the location of suspects in the famous 'RETTENDON 'RANGE ROVER MURDERS', to the production in the recent '21/7 TERRORISM TRIALS' - Cell Site Analysis (CSA) evidence has become an essential tool for investigators of serious and organised crime.


Location Mapping by the Experts
This is an important process in determining the actual operational footprint of individual and groups of telecommunication masts, cell sites, and radio signal antennae.

Comprehensive drive trials and static measurements can be carried out around a specific route, at the scene of crime, within a suspect's home address, or across an entire postal-code area. These trials measure actual site coverage utilising sophisticated radio signal data assessments, accurate positioning - confirmed via satellite triangulation - and analytical tools.

The gathered information is used as the basis for producing detailed coverage maps, where the 'spheres of service' and 'field strength surveys' for individual cell sites are illustrated in graphical form. Maps are available in many formats including aerial photography, OS ranges, A-Z street-maps, or as a 'PowerPoint' presentation.  Representations can be produced to clearly illustrate the most likely position for a communication device at a specific point in time - testing the strength of any alibi evidence.

The findings of all examinations to be documented in comprehensive Expert Reports and supported by certified and experienced Expert Witnesses that can deliver clear testimony in either civil or criminal court proceedings.
