Build essential telecoms knowledge and skills to aid forensic investigations and provide expert witness testimony.

The widespread use of mobile telephones has proven to be a useful source of information for law enforcement agencies. The ability to prove or disprove that a mobile device was used in the area of, or location of, a point of interest is invaluable. But to safely prove the case requires an understanding of cellular mobile technologies. The Critical Communications & Infrastructure Programme (Police Track) provides those working in Law Enforcement with a detailed understanding of the mobile network technologies of today and tomorrow, allowing them to conduct efficient investigations and provide compelling expert witness evidence in court.

We have combined some of our most popular training courses to build a guided learning pathway that enables you to demonstrate your expertise and competence in modern telecom technologies.

Who would benefit?

Our Critical Communications & Infrastructure Programme (Police Track) has been designed for anyone working Law Enforcement from new starters looking to build their technical knowledge from the ground up to more experienced engineers looking to formalise and expand their knowledge base. Rigorous testing, regular digital badging and certification ensures that successful students are able to demonstrate the breadth and depth of their knowledge.

This programme has been assured by City & Guilds. Assured status provides validation and recognition for the learner. It is a symbol of learning excellence and quality and is a reassurance that the training undertaken meets best practice standards.
