• Most sessions are on the 2nd Thursday at 1400 Eastern, but the September session is a week early due to the IACA conference so please verify dates/times for each session!

The Geolocation and Call Detail Record (CDR) Analysis Series is a comprehensive webinar series designed to provide in-depth knowledge on analyzing call detail records and geolocation data across various telecommunications carriers. Taught by Mike Winslow and Sarah Totten, each monthly session targets a specific carrier or application—starting with Verizon and moving through T-Mobile, AT&T, and other relevant technologies. The series includes both analytical techniques and case studies, culminating in tools for visualization and courtroom preparation. Suitable for analysts at different levels, this series equips participants with the skills required for effective and advanced telephone toll analysis. 

Students can either “mix and match” individual sessions as necessary or can purchase a series pass for all 12 sessions at a 25% discount. All sessions will be recorded and each session will award CEUs to IACA members (a certificate for each session can be requested). If you join the series pass mid-year, the price will be pro-rated and you will also receive the recordings for the previous sessions without having to wait the customary 45-day waiting period before webinars are added to the webinar library.
