Course Objectives

WCDMA/UMTS Air Interface course provides the detailed description of the WCDMA FDD technology and its use in the UMTS network. The training focuses on physical layer operation and procedures and other functions closely related with the physical layer. The training presents functionality related with the use of R99 dedicated channels. The upper layers of the UMTS air interfaces and HSPA is covered in other trainings.

Pre-requisites

The participants should have attended the UMTS Basics or have the equivalent knowledge on WCDMA/UMTS.

Training Structure

Three days training divided into logical sessions.

Methodology

Instructor led training. Theoretical exercises.
