40362 «WCDMA/HSPA Functionality Principles»

Course Code




WCDMA Functionalities is a course intended mainly for technical personnel and engineers already familiar with the WCDMA principle of operation and WCDMA air interface. It includes the idle mode behaviour of the WCDMA network, the connected mode, the necessary channel switching principles for service performance and capacity optimization and finally the power control.

Signaling messages between core network and radio access network are presented, the WCDMA UTRAN protocols and interfaces are described and the audience is introduced into the principles of troubleshooting.

At the end call setup examples are included to present as an overview the ideas
