The course is fully given in English. The course is deeply based on laboratory experiences: it allows students to practically apply the knowledge acquired during all other telecommunication courses. The course program is split in two parts: the first is devoted to the study of telecommunication networks, with particular focus on the Internet; the second part is devoted to the study of transmission systems, and specifically on digital transmission.

This course allow students to perform laboratory experiments to deepen the knowledge and practically experience about subjects introduced in Computer Networks and Digital Transmission courses. The first part of the course is devoted to telecommunication networks and is conducted in a lab, where students will use This course allow students to perform laboratory experiments to deepen the knowledge and practically experience about subjects introduced in Computer Networks and Digital Transmission courses. The first part of the course is devoted to telecommunication networks and is conducted in a lab, where students will use Personal computer and/or IP Routers to set up local network. Students will learn how to configure PCs and Routers to build local and wide area networks, to manage such networks in normal condition and deal with anomalous configuration. At the end of the course, students will be able to fully understand both local area network and Internet technologies. The second part of the course is dedicated to transmission systems. Part of the lessons will introduce new topics needed for conducting lab experiences. Students will study a typical digital transmission system and in particular will learn how to: model and simulate with a software tool; analyze signals both in frequency and time domain; evaluate systems performance in presence of additive white gaussian noise, also in presence of inter-symbol interference. The ability to apply the gained knowledge will be verified through lab exercise, as well as during the oral examination. The oral examination as well as the report on lab experiences will also help the students in improving their communication skills.

For the networking section: principle of operation of telecommunication network, especially local area networks and Internet knowledge of protocols for LAN (Ethernet) and Internet (IP, TCP, UDP, ICMP) For the system section: a good understanding of the mathematical topics presented in the first two years of the Telecommunication degree; an excellent understanding of the methodologies and techniques given during the Signal Theory course in the first semester of the third year. In addition, laboratory experiences will be based on topics presented in the Digital Transmission course, running during the same semester.

The course is based on the following laboratory experiences. Telecommunication networks (30 hours): Configuration of hosts in local area networks, IP addresses management, subnetting and supernetting Analysis of local area network: ARP and ping protocols Analysis of traffic using a sniffer: Ethernet, ARP, ICMP, TCP, UDP and HTTP protocols Interconnection of local area networks with routers: routing table configuration, route check, troubleshooting of wrong configurations Telecommunication systems (30 hours): Performance analysis of a PCM system for audio signals transmission: impact of ADC/DAC quantization and channel error probability Analysis of eye diagram for a 2-PAM binary system: noise and inter-symbol interference impact; Analysis of 2-PAM system with matched filter; Performance evaluation of digital transmission systems: error counting techniques and their accuracy; Analysis of scattering diagram for multi-level modulation formats (M-PSK e M-QAM); Performance evaluation in presence of inter-symbol interference.

The majority of the course will be given in laboratory, where groups of 3/5 students will be formed. Some theoretical lessons will anyway also be organized in class, to introduce the laboratory experiences. In the first part (telecommunication networks), students will work on Personal Computer running Linux. Using Ethernet Hubs and Switches, they will perform all required experiences. Each group will work with 3 PCs. In the second part (telecommunication systems), students will work at LAIB using Matlab.

The material related to this course will be made available in electronic format through the class Web site.

... Each group of students must prepare a written report about laboratory experiences: teachers will specify the contents during the classes. The final exam is composed of two lab experiences, similar to the ones conducted during the course, and it will last 2 hours. At the end of each experience, students will discuss their works with teachers. The oral discussion will last about 15'-20' and it will cover all topics presented during lessons and labs. The final grade will be a weighted average between the evaluation of lab report, final experiences and of the oral exam. It is possible to get some extra grades with report on specific topics, or preparing teaching material.

Gli studenti e le studentesse con disabilità o con Disturbi Specifici di Apprendimento (DSA), oltre alla segnalazione tramite procedura informatizzata, sono invitati a comunicare anche direttamente al/la docente titolare dell'insegnamento, con un preavviso non inferiore ad una settimana dall'avvio della sessione d'esame, gli strumenti compensativi concordati con l'Unità Special Needs, al fine di permettere al/la docente la declinazione più idonea in riferimento alla specifica tipologia di esame.
