1 Telecommunication Networks: B. Sc. Projects Orientation

2 © Tallal Elshabrawy 2 Preliminaries What should you gain out of your B.Sc. Project? 1.Learn the METHODOLOGY of doing a project Plan a work schedule & achieve it Being original Defy obstacles on your own Document your work Work in a team 2.Apply the information you study from different courses in one common project. 3.What kind of ENGINEER are you really going to turn out to be?

3 © Tallal Elshabrawy 3 Preliminaries What types of B.Sc. Projects are out there? Study & Design Practical &Production Research

4 © Tallal Elshabrawy 4 Preliminaries What types of B.Sc. Projects are out there? Study & Design Practical &Production Research Research: Contribute to the advancement of technology. It is challenging & satisfying to be the first to do something Aiming for a masters degree?

5 © Tallal Elshabrawy 5 Preliminaries What types of B.Sc. Projects are out there? Study & Design Practical &Production Research Study & Design: Master the understanding of material you study in different courses Develop, design and implement a simulation model

6 © Tallal Elshabrawy 6 Preliminaries What types of B.Sc. Projects are out there? Study & Design Practical &Production Research Practical & Production: Have an output product/Hardware (not just curves from a MATLAB model) A type of activity you would do possibly in work when you graduate
