"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
Comprehensive drive trials and static measurements can be carried out around a
, at the scene of crime, within a suspect's home address
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
