Learning Objectives

The course aims to achieve the following objectives, in line with the Dublin descriptors:

1. Knowledge and understanding:

Knowledge of the technologies used in mobile networks, markedly different from those adopted in fixed networks due to the characteristics of the radio transmission medium and the problems of managing users' mobility. Knowledge of the methodological tools necessary to analyze system-level performance.
Knowledge of the standards currently operational or soon to be implemented, describing the architecture of the networks on the basis of fundamental operational concepts. Specific knowledge of resource management, terminal mobility and security in mobile networks.
Knowledge of the elements characterizing mobile services already on the market and being implemented which are a driving force in the evolution of the mobile systems themselves.

2. Ability to apply knowledge and understanding:

students will be able

3. Communication skills: students will be able to rationally communicate knowledge on mobile cellular networks, with mastery of the specialized vocabulary of the sector.

4. Learning skills: students will be able to independently read standards and scientific literature of the sector, in order to update themselves on the fast evolutions of mobile radio technologies and to deepen complex issues.


Course Structure

The course mainly takes place through lectures performed both on the blackboard and with the aid of personal computers through which slides can be projected.

There are also exercises in which students are often invited to carry out the proposed exercises under the guidance of the teacher, in order to stimulate collective attention and also to obtain a random check of the learning results.

In addition, 25 hours of laboratory activities are planned.

If the teaching is given in a mixed or remote mode, the necessary changes with respect to what was previously stated may be introduced, in order to comply with the program envisaged and reported in the syllabus.
