Course Title
CDMA Technology and Its Evolution to cdma2000
- Aimed At
-
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.
- Course in a Nutshell
-
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 evryone 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).
If UMTS is the primary technology of interest to you, the discussion of cdma2000 evolution can be replaced by that of UMTS.
- Customize It!
-
There are several ways in which the course can be customized to your particular situation and requirements.
- We can tailor the topics to the needs of a particular audience, such as network design/optimization engineers or equipment/application designers.
- We can give the course a business, strategy, or operational emphasis to cater to the needs of those involved with business planning or strategy, marketing or sales, operations and support, or management.
- If WCDMA is the 3G technology of prime interest to you, we can gear the discussion to UMTS.
- If you are already familiar with the DSSS and CDMA basics and wish to focus on the cdma2000 evolution, we can do that.
- If cdmaOne (IS95) is the technology of interest to you, you can combine this course with its natural sequel, cdmaOne/IS95: Network Architecture, Operation, and Design (IS95, 2 days).
- If you’re already well versed in the RF and cellular basics, we can shorten the course or cover additional technologies (such as both cdma2000 and WCDMA) while keeping its duration the same.
