Overview

In this lecture the students will learn about the basic principles for communication systems. An important role has the layered communication protocol stack that allows for a global network with large flexibility. The different layers will be introduced and prominent protocols are discussed more in detail. Together with simple programming examples the students should understand the basic approach of communication networks. The lecture will also link the teaching content with ongoing research activities at the chair.
