INDUSTRIAL AUTOMATION ENGINEERING - INGEGNERIA DELL'AUTOMAZIONE INDUSTRIALE
Industrial Technologies and Management
Primo Semestre (28/09/2020 - 22/01/2021)
45 ore di attività frontale
Give students the knowledge to understand problems and technical solutions to operate a communication system. Impact of the environment and of the service type on the preferable solution. Description of the main commercial systems with reference to the studied techniques. It is assumed that students don’t have any background in telecommunications, and will be more interested in their exploitation in industrial environments. As a consequence, the theoretical aspects will be limited and focus will be on application examples. At the end of the course, it is expected that the student will know:
- The physical principles that affect a transmission system
- The transmission techniques and their effectiveness in presence of above mentioned phenomena
- Effects of the interaction between different users and services
- The reasons behind the choices of different techniques in different systems
- The performance that can be achieved and the factors influencing them
All this with the final aim to give students the tools to analyze requirements and consequently adopt a conscious choice based on the requested service.
