Objectives

The mobile radio network course is designed to provide students with the tools to learn about and evaluate the main cellular telecommunication systems, starting from the first generation systems, up to providing an outline of future 5G systems. During the course, the main simulation tools for mobile networks will be analyzed.
Knowledge and understanding:
At the end of the course the student must know and understand:
- the architecture (components and functions) of the mobile radio networks;
- the functioning mechanisms of the modulation systems used;
- the main activities carried out for the design and management of a mobile radio network

Ability to apply knowledge and understanding
At the end of the course, the student must:
- to be able to analyze the behavior of a mobile radio network
- know how to identify the characteristics of a mobile radio network in order to design a part to meet the specifications.
- know how to use the methodologies to correctly configure a mobile radio network based on the characteristics of the channel.
- know how to apply the tools and criteria for analyzing the properties of mobile radio networks.
- know how to define the parameters of a mobile radio network based on standard specifications.
- know how to design advanced digital telecommunications systems and understand the project specifications required for the construction of mobile radio networks and provide adequate solutions.

Autonomy of judgment
At the end of the course the student will know the main solutions currently available for cellular networks in terms of network architecture, protocols, interfaces, procedures and management of radio resources.

Communication skills
At the end of the course, the student must be able to illustrate in an organic way the interdependence of the different modules that make up a mobile radio network.

Learning ability
The evolution of mobile devices requires a high capacity for autonomous updating. The course will enable students to independently understand the technical documentation made available by the telecommunication system producer communities and by the main software development companies with particular reference to radio frequency systems for mobile radio networks.

Prerequisites

Lexical: comprehension and use of technical-scientific language, in particular concerning physics and mathematics
Computer scientists: ability to use / learn tools and basic software for scientific computing
Communicative: knowing how to present concepts and information in oral, written and graphic form
Organizational: know how to organize activities throughout the day and plan a medium-term work / study plan
Cognitive: Fourier transform, signal theory, probability theory.
Skills: ability to define the link between physical phenomena, their properties and their representation both mathematically and graphically.
This knowledge, skills and competences are usually acquired during the first level degree courses.

Teaching Methods

The course is organized with
- lectures with the support of graphic presentations
- exercises based on LabVIEW simulation software,
- practical exercises on hardware systems (spectrum analyzers, signal generators, SDR card antennas)

The teacher is available to provide explanations and clarifications both during the interval between consecutive hours of lessons, and during the time of receipt or by appointment, both by e-mail, IM and social networks on the official page of the course of study.

Verification of learning

During the course a series of projects to be carried out in itinere organized in groups of 3 will be assigned using the simulation software used during the laboratory exercises. These projects will be evaluated with a score of 10/30. The verification of the learning is carried out at the end of the course through a written test that can contain
- open-ended questions
- numerical exercises
in order to verify
- the knowledge
- the skills
- skills
covering the entire course program. A maximum score is assigned to each question / exercise. Each exercise is evaluated with a score between 0 and the maximum score assigned. The maximum score is assigned in case of a correct answer, while a lower score is assigned in the presence of errors. Distraction errors or due to misunderstandings of the text attributable to possible ambiguity in the text itself, will have a lower weight compared to conceptual errors clearly caused by a partial knowledge of the subject. The maximum sum of scores obtained in the questions / exercises will be equal to 22/30.

The final grade is obtained as the sum of the scores obtained in each year and the score assigned to the ongoing project. The maximum score of the test is 32. Whoever obtains an overall score of 32 will have a grade of 30 and honors.
