OVERVIEW

The teaching unit in Telecommunications introduces the student to the fundamental concepts related to the representation in time and frequency of electrical signals in a way suitable for transporting information from a source (transmitter) to a destination (receiver). describing the use of wired and wireless networks for the transmission of signals in different application areas with particular reference to the main protocols and standards.The teaching unit in Telecommunications introduces the student to the fundamental concepts related to the representation in time and frequency of electrical signals in a way suitable for transporting information from a source (transmitter) to a destination (receiver). describing the use of wired and wireless networks for the transmission of signals in different application areas with particular reference to the main protocols and standards.

AIMS AND CONTENT

LEARNING OUTCOMES

The aim of the teaching unit is to provide students with the basic knowledge to understand the fundamental principles on which the most modern technologies for the transmission of information at a distance are based, using digital representations suitable for their processing, coding and transmission on telecommunication networks, in particular the Internet, through both wired and wireless access technologies for applications in the Internet of Things.

AIMS AND LEARNING OUTCOMES

The teaching accompanies the student's learning starting from the description of the overall scenario relating to the transmission of information at a distance through the use of representations, signals, networks and digital systems. The concept of information source and the growing importance of its use in the design and management of complex intelligent systems will be introduced initially. Scientific bases and technological solutions will be provided to obtain a compact and protected digital representation of information and then the fundamental principles of electrical communications and therefore the processing necessary to transfer information at a distance in a reliable way on a communication channel, whether wired or wireless, will be introduced. The main technologies of radio access on local networks (for example wifi) and mobile radio access cellular will be introduced and compared, including the integration between terrestrial and satellite networks. The Internet will represent the leitmotif of a good part of the teaching through the description of its main characteristics, the operating mechanisms, the protocols and the main applications in the modern context of the Internet of Things.

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 unit will include frontal lessons with the use of both a traditional blackboard and slide and video projection.

Students who have valid certifications for Specific Learning Disorders (DSA), for disabilities or other educational needs are invited to contact the teacher and the contact person for disabilities of the Polytechnic School, Prof. Federico Scarpa (federico.scarpa@unige.it), at the beginning of the course to agree on any teaching methods that, in compliance with the objectives of the course, take into account individual learning methods

SYLLABUS/CONTENT

In the first part of the course, the concept of information source will be introduced, its binary representation through coding processes, then the problem related to the noise of the transmission channel and the need for suitable information protection policies.

The fundamental concepts of description of an electrical signal will then be introduced, its characterization in the time and frequency domain and the objective to be applied properly to transfer information over a distance.

The fundamental concepts of Linear Time Invariant Systems (LTI), of Input/output relations and their work to create filters will be reviewed. The principles of sampling of continuous signals and their reconstruction, the techniques of quantization and digital representation will be described. Then the basic principles of multiple access and digital modulation.

The fundamental concepts, functional and architectural, of a wired digital communication network will be introduced later, with particular reference to Internet protocols. The Wifi wireless access network will also be described.

Finally, the basic principles for the implementation of terrestrial cellular mobile wireless networks and their interoperability with satellite networks will be described. New technologies supporting IoT applications such as NB-IoT, EC-GSM, LTE-M, RFID, Bluetooth, Lora will be illustrated.

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

RECOMMENDED READING/BIBLIOGRAPHY

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

EXAMS

EXAM DESCRIPTION

Written test divided into two sub-tests for each of the teaching parts of the two teachers, to be held on the same day and in the same classroom in succession. Possible oral examination upon request of the student even for only one specific sub-test in case of sufficient written test. Final grade of the course equal to the arithmetic mean of the grades of the two sub-tests. Validity of the grade of each individual sub-part equal to 12 months from the date of achievement or earlier in case of delivery of a new attempt in subsequent tests.

ASSESSMENT METHODS

The written tests of each sub-part will be aimed at ascertaining the correct understanding and assimilation of the main theoretical contents as well as the autonomy achieved in setting up and solving simple exercises. The tests may consist of a single problem or a set of closed or open-ended questions. The tests will be held in person and may use telematic methods on Aulaweb by requiring students to have a personal notebook/tablet.
