Cell Site Analysis Awareness – Law Enforcement

This Cell Site Analysis Awareness course will cover these main topics:

• What is Cell Site Analysis – Introduction and basic description of the process used and the methods applied in conducting Cell Site Analysis.
• Mobile Telephone Networks – Explanation around what mobile telephone networks there are and what cell sites look like, sectors, theoretical coverage.
• Factors that affect the perfect network – An explanation of RF signal propagation, the difference between wavelength and frequencies, what high and low frequencies look like, reflection, diffraction.
• RF Signal Propagation – Further in depth look at sectors of cell sites and azimuths. What an azimuth is, what can affect signal propagation.
• Typical Coverage Areas – Comparison of cell types and potential coverage. Covering single and free sectors of a cell site. The difference between different cell sites including omni-directional and sectorised cells. Discusses the difference between picocells, microcells, macrocells and femtocells.
• Cell Density – Visual guide and understanding. Comparing the cell density in urban and rural areas.
• Call Data Records – How they can be obtained and the type of data we can receive.
• Cell Site Location Information – Explanation of what is recorded on the CDR and what conclusions can be made solely on that.
• Mapping CDR – Demonstration of what is mapped & presented from CDR. How CDR can be visualised and show theoretical coverage to determine where or not it is worth doing a survey.
• RFPS – RF Surveys – The process and how they are conducted. What we do in the end-to-end process, the considerations on if we should be conducting a survey and the strategy behind it. Where they are beneficial and where they aren’t beneficial.
• Equipment Used – What equipment is used to conduct a survey, limitations of their use. The limitations of different types of equipment and best practices.
• Serving & Neighbouring Cell Information – Detailed explanation on this topic. Different between a serving cell and neighbouring cell and how it affects their investigations.
• Evidential Considerations – Start & Ends cells, what this infers in an investigation and debunking myths around it. Data Sessions and the interpretations that should be made and common questions raised.
• GPRS – Explanation around its limitations, myths and improvements.
• Colocation Analysis – Explanation when this can be used. Reviewing the pattern of behaviour of two or more devices and understanding how the devices can be moving around together.
• Network Issues and Contingencies – Examples that support the use of RF Surveys in investigations.
• Q & A session – Ask our Senior Cell Site Analysts any questions about Cell Site Analysis and their experience.
