Frequently asked questions

What are Call Detail Records (CDRs)?

Call Detail Records (CDRs) are logs created by telecommunications carriers that document phone activity such as calls, text messages, and data events. They typically include information like date, time, duration, and the cell tower used during a communication, but do not contain the content of the communication itself.

Who should take a CDR analysis course?

This course is designed for investigators, attorneys, analysts, and legal professionals who need to understand and interpret phone records. It is especially useful for those involved in criminal investigations, litigation, or digital evidence review.

Do I need a technical background to understand CDRs?

No. This course is designed to be accessible to non-technical learners. It explains telecommunications concepts, terminology, and analysis methods in a practical, easy-to-understand way without requiring prior engineering or forensic experience.

How are CDRs used in investigations?

CDRs are commonly used to build timelines, identify communication patterns, and establish potential connections between individuals. They can support investigative leads but should always be interpreted carefully and in context with other evidence.

Will this course teach advanced forensic or cell phone extraction techniques?

No. This course focuses on understanding and analyzing carrier-generated records, not on forensic data extraction or advanced engineering techniques. It provides a strong analytical foundation but is not a substitute for specialized forensic training.
