UMTS

Overview



Goals of the Overview

• Understanding of the Aims of UMTS

• Global Vision of the Present Status of the Market

• General System Architecture of UTRAN - FDD

• Basic Characteristics of UTRAN - FDD

• Performance of UTRAN - FDD

Main Goal, Answer to: How UTRAN - FDD

Works?



UMTS Overview Method (I)

• Duration of the Course: About 12 Hours.

• Material of the Course: One Book and One Presentation Based on

Slides

• The Method: During the Course, Only the Presentation Will Be Used

• The Book: – Covers all the Contents that the Presentation Covers

– Details these Contents in a Deeper Way

– Not Used During the Presentation (for Students’ Knowledge

Enhancement)



UMTS Overview Method (II)

• The Presentation:

– Based on 15 Main Slides

– These Slides Will Allow the Explanation of the Main Topics (to Achieve

the Goals of the Overview)

– Each Slide Covers Several Issues

– There Is no One to One Correspondence Between the Book and the Slides

of the Presentation
