Introduction:

3G | WCDMA | CDMA2000 Training in Depth Course Description

This fast-paced, five-day 3G | WCDMA | CDMA2000 Training in Depth course will help those familiar with 2G technologies migrate to 3G systems. The 3G | WCDMA | CDMA2000 Training in Depth course begins with a review of the digital modulation techniques, radio propagation characteristics, and performance improvement techniques. This is followed by a comprehensive discussion of the system building blocks and various system operating scenarios for both the CDMA2000 and WCDMA systems. The 3G | WCDMA | CDMA2000 Training in Depth course concludes with a study of the link budget spreadsheets and system capacity examples.

Customize It:

● If you are familiar with some aspects of this course, we can omit or shorten their discussion.
● We can adjust the emphasis placed on the various topics or build the course around the mix of technologies of interest to you (including technologies other than those included in this outline).
● If your background is nontechnical, we can exclude the more technical topics, include the topics that may be of special interest to you (e.g., as a manager or policy-maker), and present the course in manner understandable to lay audiences.
