The course aims to introduce students to the main telecommunications standards that allow to access to the network and to exploit its resources.
The classes will be supported by demonstrations and practical laboratory works.
In detail, the training objectives, tailored according to the Dublin Descriptors, and in accordance with the educational objectives of the Master of Science in Technologies for Internet Engineering, are the following.
Knowledge and understanding
The student, at the end of the course should know and understand:
- characteristics and functionalities of the main telecommunication standards to access to the network, from the commonly used to the latest generation ones;
- main protocol specifications that characterize the main access standards;
- the operative mechanisms of the network devices used to access and distribute the resources.
Applying knowledge and understanding
The student, at the end of the course, will:
- be able to describe, analyze and contextualize the telecommunication standards that characterize the main access techniques;
- be able to analyze and identify compatibility, coexistence, and interference issues between different access standards;
- know how properly configure a telecommunications system that use access tehniques characterized by the presented standards;
- know how define the parameters of a system based on standard specifications.
The student, at the end of the course, will be able to distinguish the main features of the standards that manage the access to the network and will be able to evaluate which might be more appropriate in a given scenario and/or according to operational requirements.
The student, at the end of the course, will be able to describe, in a comprehensive way, the main features of telecommunication standards presented. Moreover, he will be able to show connections (potential) between the protocols of the individual protocol stacks.
The course will make students autonomous in order to understand technical documentation published by international standardization groups, with particular reference to the network access standards.
Lexical: understanding and using ability of technical-scientific language, in particular physics and mathematics.
IT: usage / learning skills of tools and basic software for scientific computing.
Communication: knowing how to present concepts and information in oral, written, and graphic form.
Organizational: how to daily organize activities throughout a short / medium term planning.
Cognitive: Digital Transmissions, Digital modulations, Fading, Telecommunication Networks.
Skills: ability to define connection between physical phenomena, their properties and their representation in both mathematical and graphical form.
These knowledge, skills, and competence are acquired during the bachelor degree courses and thanks to the course "Wireless Transmissions".
The course aims to introduce students to the main telecommunication standards that allow access to the network and to exploit its resources.
The course is temporally organized in the following training units.
Cable access techniques (10 theory, 6 Lab):
- Twisted pair;
- Optic fiber.
Access techniques for wireless personal area networks - WPAN (10 theory, 4 Lab):
- Bluetooth – Bluetooth Low Energy;
Access techniques for wireless local area networks (6 theory, 4 Lab):
- WiFi and 802.11 standard;
- WiMax and 802.16 standard.
Access techniques for low power wide area networks (5 theory):
Notes on satellite communications and positioning (2 theory)
Notes on the last generation access techniques (3 theory):
- Vehicle networks and 802.11p standard;
- Cognitive radio and 802.22 standard;
- Standard IEEE 802.19.
The course is organized with
- Lessons with graphic presentations support
- Exercises based on the use of lab instrumentation, LabView, and Matlab simulation software
- Practical exercises on the use of hardware systems (Network equipment, spectrum analyzers, signal generators, antennas, and SDR adapters)
The material is available in the official website of the course.
The teacher is available to provide explanations and clarifications both during the interval between consecutive class hours and by appointment, as well as by e-mail, Skype, or through the official Facebook page of the course of study.
Verification of learning
The exam is at the end of the course through a written test which may contain:
- Short-answers tests
- Simple practical problems
in order to verify
covering the entire course program. Each application / exercise has a maximum value. Each exercise is evaluated with a score between 0 and the maximum score assigned. The maximum score is assigned in case of correct answer while a lower score will be ssigned in presence of errors. Lack of attention or misunderstandings mistakes, as well as text errors attributed to possible ambiguity will have a lower weight than conceptual errors, clearly caused by a partial knowledge of the subject.
The final grade is obtained as the sum of the scores obtained in each year. The maximum score of the test is 32. Who gets an overall score of 32 will have a vote equal to 30 cum laude.
