Telecommunication Systems

Objectives

Provide the students with knowledge on current telecommunication networks in order to understand their main characteristics. 

The emphasis goes to the general architectures (both in terms of hardware and software) and to the way the networks are defined based on reference models. 

It is also an objective that the students become familiar with the various physical layers (guided, not guided, etc.) and feel the need for a data link layer as well as the medium access control sublayer to access a shared medium. For each layer (or sub-layer) some real networks are studied. It is important that the students acquire enough critical knowledge about the main technical choices made for each of the example networks. The theoretical syllabus goes up till the Network layer (excluding it). 

The laboratory part consists on learning how to use the socket interface both using TCP and UDP in order to provide the students of enough knowledge that will be important in future courses in the degree.

Teaching method

The lectures consist mainly of the presentation of the theory, but they also include exercises and demonstrations of the use of the learned systems (e.g. 802.11).

In the lab classes the students learn Java and implement various projects where they use the network interface and apply their knowledge on error control and on the telecommunication’s network structure.

The weights of the theoretic and practical parts are 75% and 25%. There is a minimum of 9 and 9,5.

The theoretic part can be obtained by 3 assessment mid-term tests or a final exam

The practical component consists of various projects. The assessment of the projects is accomplished in group discussions with individual grades, covering the theoretical and practical aspects of the project.
