82089 - Radioprotection and Spectrum and Management M

Course Unit Page

Academic Year 2021/2022

Learning outcomes

Provide the criteria for evaluation and control of electromagnetic fields in terms of interference and environmental impact. This course aims at providing the basis of generation, propagation and interaction of electromagnetic fields with the environment and with biological systems, related to radio frequencies. Students will learn how to identify the main transmission characteristics for industrial and residential electromagnetic sources (radio broadcasting systems, cellular mobile radio systems, household (electrical) appliance, industrial equipment, etc.) and the main bioelectromagnetics mechanisms of interaction. Moreover student will have gained the capacity to identify the suitable prediction models and measurement tools in order to survey, assess and mitigate electromagnetic field exposure. This course is designed in order to provide direction for radio systems frequency planning and radio spectrum efficiency use.

Course contents

Radio-frequency electromagnetic field sources and their characterization: radio frequency identification systems (RFID), radio access systems (WiFi and WiMAX), mobile systems (GSM, UMTS), broadcasting systems (DVB T, DVB-H, DAB).

Evaluation of electromagnetic exposure in free space and in real environments.

Measurement and equipment for personal and environmental survey of electromagnetic exposure.

National and international regulations on environmental protection and the exposure for public and workers.

Interaction between electromagnetic fields and biological systems: in vitro and in vivo exposure systems, experimental studies and epidemiological studies.

Risk and risk perception: the importance of the communication in risk perception.

Frequency management and planning: spectral efficiency, licensed and unlicensed frequency bands, licensed shared access, interference between systems operating in adjacent bands.

Practical applications: wideband and narrowband electric and magnetic field measurements

Assessment methods

The exam is organized into a written and a following oral test. The written test is a multiple choice test aiming at assessing the knowledge of general concepts provided to the students during the course. The use of books and notes is not allowed. The outcome of the test is expressed by a mark (out of 30) which should be positive (i.e. at least 18 out of 30) in order to proceed with the oral discussion. The oral discussion aims at assessing the comprehension of the main concepts explained during the course. Written and oral tests should be preferably held on the same exam session; in any case the validity of the written test score is limited to the current academic year.

The final mark is the synthetic evaluation of both written and oral tests.
