Telecommunication Networks: B. Sc. Projects Orientation
© 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?

Preliminaries
What types of B.Sc. Projects are out there?
Study & Design Practical &ProductionResearch
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
