OVERVIEW

Telecommunication teaching is divided into three fractions. The first fraction introduces the student to the fundamental concepts related to the representation of electrical signals in time and frequency in a way suitable for to transfer information from a source (transmitter) to a destination (receiver). The second and third fractions are carried out in parallel and describe the use of wired and wireless networks for the transmission of signals in different application fields with particular reference to the main protocols and standards.

AIMS AND CONTENT

LEARNING OUTCOMES

The aim of the course is to provide the basic elements to understand the problems connected to the transmission of information on a communication network and the management of a communication network.

AIMS AND LEARNING OUTCOMES

Students will learn the use of electrical signals to remotely transfer information in a typical application context where the information source (sensor) is physically distant from the computing resource that will process the information (server, cloud) and from the one that will use it to perform actions (actuator). The student will acquire knowledge of the main methods for representing electrical signals in the time and frequency domain, the conversion of continuous electrical signals into discrete and digital signals, source coding, channel protection and the main digital modulation techniques. The student will learn the functioning and potential of use in real applications of both wired and wireless digital transmission networks.

PREREQUISITES

The knowledge of basic concepts of probability, stochastic processes, representation in series of functions, autocorrelation are useful prerequisites for an optimal learning.

TEACHING METHODS

The teaching will include frontal lessons with the use of both traditional blackboards and projection of slides and videos. There are exercises on the signals part with the use of Matlab simulation software or equivalent.

SYLLABUS/CONTENT

The first fraction will introduce the concept of electrical signal, its characterization in the time and frequency domain and the use of the forward and inverse Fouruer transform. The fundamental concepts of Linear Time Invariant Systems (LTI), of the Input/output relationships and of their use to create filters will be taken up again. The principles of sampling of continuous signals and their reconstruction, the techniques of quantization and digital representation will be described. Finally the basic principles of multiple access.

In the second fraction, the fundamental functional and architectural concepts of a wired digital communication network will be introduced with particular reference to Internet protocols. We will also describe the Wifi wireless access network.

In the third fraction methodologies of source and channel coding, digital modulation and transmission on both broadband (2G, 3G, 4G) and narrowband wireless and mobile networks will be introduced for both terrestrial and satellite IoT applications.

The teaching contents will provide students with skills useful for achieving the various objectives of the 2030 Agenda, in particular the telecommunications solutions that will be investigated will provide skills in the design of smart solutions for the optimized management of production plants attributable to Objective 9 "Enterprises Infrastructure Innovation", as well as the implementation of effective policies for Smart Cities attributable to Objective 11 "Sustainable Cities and Communities".

RECOMMENDED READING/BIBLIOGRAPHY

All the contents of the three fractions are covered entirely by material made available and consisting of slides and handouts. Reference textbooks will be indicated for further study.
