Cell Site Analysis

cell site analysis expert witness Cell Site Analysis (CSA) is the science of reconstructing the physical movements of a mobile telephone or telecommunication 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.

Cell Site Analysis: from undermining the alibi of IAN HUNTLEY in the SOHAM MURDERS, the reconstruction 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.

AFENTIS FORENSICS provide independent and professional services for all aspects of Cell Site Analysis (CSA), radio frequency and Call Mapping (CM) – whether examinations are historic in nature or concerning ‘live’ data/subjects’. ‘LOCATION MAPPING’ is an important process in cell site analysis investigations, determining the actual operational footprint of individual and groups of telecommunication masts, cell sites, and radio signal antennae.

Cell Site Analysis

Comprehensive cell site analysis 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 mast coverage utilising sophisticated radio signal data assessments, accurate positioning – confirmed via satellite triangulation – and powerful 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.

Our cell site analysis analysts contribute to a number of leading working groups as well as undertaking constant research into these spheres, to ensure our approaches to Cell Site Analysis (CSA) remain in touch with Best Practice. Telecommunication analysts at Afentis Forensics have access to the very latest in electronic evidence tools and techniques – including the world’s most advanced Cell Site Analysis investigation system; engineered exclusively in-house and utilised by investigators and police forces around the world.

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