Knowledge of technologies used in mobile networks, markedly different from those adopted in fixed networks due to the characteristics of the radio channel and management of user mobility. Ability to carry out the planning of a mobile network. Knowledge of current operating standards. Knowledge of the features of the mobile services already present in the market and next.
The student must acquire the ability to rationally communicate his knowledge on the subjects of the course topics, with specialized vocabulary in the field. Ability to read independently standards and scientific literature in order to keep abreast of rapid developments in mobile radio technologies and to investigate complex issues.
