Pre-Conference Seminar: Understanding Telecommunications Technologies for LEA Investigators and Intelligence Analysts

9:00 - 16:30, Tuesday, 2 June 2009

Presented By: Drs. Jerry and Matthew Lucas, TeleStrategies

This pre-conference seminar is for law enforcement, interior security and intelligence analysts who have to understand telecommunications technology buzz words and jargon in order to communicate with telecom operator engineers regarding their Intelligence Support System (ISS) requirements regarding lawful interception, investigative analysis and intelligence gathering with intercept case study challenges. Seminar sessions include:
