Course Description:

'' Since all future technologies, 3G and beyond, will employ some form of CDMA, understanding the theory of CDMA and the common underpinnings of all CDMA-based networks is imperative for everyone already in or entering the field of mobile wireless technology, including those who work with UMTS. Imparting such understanding is the objective of this course.

In this course, we will lead you step-by-step from the propagation and fading of radio waves through the general principles that underlie the architecture and operation of all cellular networks to the basics of Direct Sequence Spread Spectrum (DSSS), the foundation of all CDMA systems.

Having mastered these key concepts, you will learn how several of the important features of CDMA are implemented in cdma2000 including system capacity and soft capacity, soft (and softer) handover, and RAKE receiver, to name a few. We will study the entire process of cdma2000 evolution from IS95 to 1xRTT and EVDO, as well as the future 2008 releases, viz., EVDO Revision B and C (UMB)

Audience:

Those experienced with a non-CDMA technology who wish to work with any of the CDMA-based technologies, including cdmaOne (IS95), cdma2000 (1XRTT, EVDO, UMB, EVDV) or WCDMA (UMTS-FDD, UMTS-TDD) families of technologies.

Prerequisites:

The standard presentation of this course assumes a technical background and some prior exposure to wireless, though the course can be adapted to other needs.

Customize it:

This 3-4-day course will be customized to your needs and specifications. Eno.com will assist you in identifying those needs and specifications. A word to the wise, there are many vendors of wireless training. They will typically have a broad and general course, one size fits all, already developed and just put your organization’s name on the title slide. This minimizes their effort and time investment. At Eno.com, every course is made to your exact and exacting specifications. We help you ensure what you are getting is what you really need even if at the beginning you weren’t too sure of what that was. We fit the class to your needs. We never fit you into our “standard� one size fits all, class.
