1Telecommunication Networks: B. Sc. Projects Orientation
2Preliminaries What should you gain out of your B.Sc. Project? Learn the METHODOLOGY of doing a projectPlan a work schedule & achieve itBeing originalDefy obstacles on your ownDocument your workWork in a teamApply the information you study from different courses in one common project.What kind of ENGINEER are you really going to turn out to be?
3Practical &Production PreliminariesWhat types of B.Sc. Projects are out there?Study & DesignPractical &ProductionResearch
4Practical &Production PreliminariesWhat types of B.Sc. Projects are out there?Study & DesignPractical &ProductionResearchResearch:Contribute to the advancement of technology.It is challenging & satisfying to be the first to do somethingAiming for a masters degree?
5Practical &Production PreliminariesWhat types of B.Sc. Projects are out there?Study & DesignPractical &ProductionResearchStudy & Design:Master the understanding of material you study in different coursesDevelop, design and implement a simulation model
6Practical &Production PreliminariesWhat types of B.Sc. Projects are out there?Study & DesignPractical &ProductionResearchPractical & 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
