1xEV-DO Course Description

This 2 (or 3) day course provides a practical look at many of the key features and operational aspects of a cdma2000 1x Data-Only (1xEV-DO) system. The course begins with a quick overview of CDMA technology and the contrasting elements and unique techniques associated with 1xEV-DO operation. It then continues with a description of the Physical Layer with regards to both the forward and reverse links. The MAC Layer functions are described, including Power Control, Data Rate Control and Scheduling. Call processing is discussed in detail and the associated messages are listed and described. The course then investigates the different handoff methods involved with a 1xEV-DO system, and ends with a discussion on the implications of a hybrid (1xRTT and 1xEV-DO) network and examples of hybrid traffic call flows and interaction with the IP domain.

Course Objective: Upon completion of the course the student will have a basic understanding of the 1xEV-DO technology as described and documented in the IS-856 standard and as it relates to other relevant standards.
