This course develops the skills required to competently interpret UK Call Data Records (CDRs) for evidential and intelligence purposes. Through a blend of online learning and practical classroom exercises, delegates learn how to cleanse, normalise, and manually analyse communications data in line with forensic best practice and the FSR Code of Practice (DIG-200).

The course focuses on building confidence in CDR interpretation across all UK networks, understanding evidential limitations, and clearly explaining findings within a forensic and investigative context.

You’ll learn:

  • Fundamentals of cellular networks and CDR generation

  • Manual interpretation of voice, SMS, and data records across UK networks

  • Cleansing and normalising raw CDR datasets

  • Interpretation of data sessions, DDRs, and network-specific record structures

  • Applying evidential limitations and appropriate caveats

  • Demonstrating competence through practical assessment aligned to FSR DIG-200

Suitable for:

Police analysts, digital investigators, and RF technicians involved in communications data analysis at any experience level.
