Telecommunication Networks: B. Sc. Projects Orientation
2
Preliminaries What should you gain out of your B.Sc. Project?
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 Apply the information you study from different courses in one common project. What kind of ENGINEER are you really going to turn out to be?
