AIMS AND CONTENT

LEARNING OUTCOMES

The Internet society is based on technological solution for continuative and pervasive connection of persons and objects (IoT). In the module, different radio technologies are investigated and compared able to guarantee such global connection, including terrestrial and satellite solutions. Radio coverage strategies will be examined by comparing different cell planning methodologies. Terrestrial mobile telephone standards like GSM/GPRS, WCDMA and LTE will be examined and compared with satellite technologies like Globalstar and Iridium. The smartphone platform will be considered as a multi-standard platform able to connect persons and things beyond the telephone network, including Wifi, Bluetooth, RFID, BLE, NFC. The added value represented by position estimation of terminal, persons and things will be considered with reference to applications for logistics, transportation and health. In such view, methodologies based on terrestrial radio fingerprinting and satellite-based global systems (GPS/Galileo/Egnos) will be introduced.

AIMS AND LEARNING OUTCOMES

At the end of the class students are expected to know and manage the main problems associated to radio communication either terrestrial or satellite based. They should demonstrate deep knowledge of the solutions and techniques for radio cellular coverage, terminal localization, radio resource allocation, inteference management and mobility support. They will have confidence in designing radio links by budgeting transmission power, antenna gain and propagation losses. The exam will be based on assessing the theoretical knowledge as well as the design ability. Cases studies will be investigated concerning specific applications in logistcs, transportation, industrial operation and medical assistance.

TEACHING METHODS

The class will be based on  traditional lessons with explanations and exercises on the blackboard or through slide and video projection.

Lessons will deal wth theoretical explanatios followed by exercise sessions in laboratory using radiofrequency instrumentation to concretely verify basic theoretical concepts.

EXAMS

EXAM DESCRIPTION

The exam consists in a written test with exercises, questions with multiple choice answers, questions with open text answers. In case the test is passed, students can optionally sustain an oral exam.

ASSESSMENT METHODS

The student level of learning is assessed through exercises oriented to solve practical problems requiring the correct use of formulas and through questions oriented to verify the comprehensive knowledge of specific arguments. 

Students with learning disorders ("Disturbi Specifici di Apprendimento", DSA) will be allowed to use specific modalities and supports that will be determined on a case-by-case basis in agreement with the delegate of the Engineering courses in the Committee for the Inclusion of Students with Disabilities.

FURTHER INFORMATION

Students who have a valid certification of physical or learning disabilities on file with the University and who wish to discuss possible accommodations or other circumstances regarding lectures, coursework, and exams should speak both with the instructor and with Professor Federico Scarpa (federico.scarpa@unige.it ), the School's disability liaison.
