Cell Site Analysis Expert Witness for Mobile Location Evidence

• Examining which cell towers a phone connected to during calls or data use.
• Correlating call data records (CDRs) with cell site information to determine possible phone locations.
• Analyzing cell coverage, orientation, power, network usage, and physical geography affecting signal reach.
• Producing cell site mapping and radio frequency propagation surveys (RFPS).

• Reviewing network logs that record each interaction of a phone with the network.
• Identifying the time, duration, and connection details to specific cell towers.

• Establishing the general or approximate position of the phone at specific times.
• Mapping movement during key periods by analyzing sequential cell connections.
• Co-location analysis to determine if multiple devices were in the same place or possibly used by one individual.

• Using specialist equipment to measure coverage areas of cells physically or through drive testing.
• Incorporating survey data into the analysis to enhance accuracy.

• Assessing whether the phone was used by the alleged person based on usage patterns.
• Comparing data with other sources like handset content, WiFi usage, or tracker and telematics data.

• Preparing clear, accurate expert reports explaining the technical findings.
• Providing testimony in criminal and civil courts about mobile phone location evidence.
• Ensuring evidence is not misinterpreted and assumptions are carefully explained.

• Combining cell site analysis with other data sources like CCTV or witness statements.
• Cross-referencing phone location evidence to validate or refute alibis.

• Drug conspiracies and trafficking (e.g., supply of Class A drugs, county lines operations) where phone location links suspects to crime scenes or conspirators.​
• Murder and violent crime investigations to place suspects or victims at relevant locations.​
• Missing persons cases, where cell site data helps trace last known whereabouts.​
• Cases involving conspiracy and organized crime, where phone use patterns are vital evidence.​

• Challenging prosecution cell site evidence through expert analysis to identify data limitations, errors, or false inferences.​
• Demonstrating alibis or disputing phone attribution to defendants.​

• Disputes regarding location evidence, such as in insurance claims or accident reconstructions can also use cell site analysis (though less common).

• Identification and location evidence in fraud or corporate crime investigations.
• Family law disputes concerning contact or custody where location and time data are relevant.

Cell Site Analysis involves examining mobile phone connection data—such as call data records (CDRs) and mast information—to establish where a device was likely located at specific times. It’s commonly used to link individuals to crime scenes, support or dispute alibis, or show patterns of movement in criminal, civil, and family law proceedings.

Our Cell Site Experts provide technical analysis and expert opinion on the accuracy and limitations of mobile phone location evidence. This may include interpreting call records, producing cell site maps, analysing network coverage, testing signal strength, and explaining whether a phone could realistically have connected to a particular mast at a given time.

Yes. Each Cell Site Expert Witness is frequently instructed by criminal defence solicitors to assess the reliability of prosecution evidence. This includes identifying flawed assumptions, technical limitations, or errors in how the data has been interpreted. A well-structured rebuttal report can be key to undermining weak or misleading location claims.

Cell Site Data can show where a phone was likely located, but it cannot pinpoint exact locations with GPS-level precision. Our experts clearly explain these limitations in their reports and testimony to ensure the evidence is not misinterpreted or overstated in court.

Cell Site Analysis is most commonly used in serious criminal cases such as drug conspiracies, murder, organised crime, and missing persons investigations. It is also relevant in civil matters such as insurance disputes, accident reconstructions, and some family law cases involving contact or custody arrangements.

Yes. All of our Cell Site Expert Witnesses are experienced in giving oral evidence and cross-examination in both criminal and civil courts. They produce reports in full compliance with Criminal Procedure Rules Part 33, Civil Procedure Rules Part 35, and the Forensic Science Regulator’s Code of Practice and Conduct.

Where required, our Cell Site Experts can conduct Radio Frequency Propagation Surveys (RFPS) to test the actual coverage of specific cell towers in real-world conditions. This helps support or challenge claims about phone location with physical evidence.

Yes. Provided that the relevant Call Data Records and network information are available, our experts can analyse historic phone activity, even from several years prior, to reconstruct likely movements or test prosecution assumptions.

All of our Cell Site Expert Witnesses work at legal aid rates, ensuring their services are both affordable and of the highest evidential quality. Our quotes are fully itemised to support funding applications and cost assessments.

We offer nationwide coverage, with experts available across the UK, including London, Manchester, Liverpool, Leeds, Birmingham, and surrounding areas. Remote report work and digital evidence reviews are also available for efficiency.

Absolutely. Our Cell Site Experts are often instructed by the defence to demonstrate alibis, dispute mobile phone attribution, or show that a device could not have been at a claimed location. Their impartial, technical insight can be pivotal in undermining unreliable prosecution evidence.
