PERVASIVE COMMUNICATION AND CONTEXT AWARENESS
OBIETTIVI E CONTENUTI
OBIETTIVI FORMATIVI
The Internet society is based on technological solution for continuative and pervasive connection of persons and objects (IoT). In the course, 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.
OBIETTIVI FORMATIVI (DETTAGLIO) E RISULTATI DI APPRENDIMENTO
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.
Modalità didattiche
The class will be based on both traditional frontal lessons and telepresence live lessons provided through MS Teams platform.
Lessons will deal wth theoretical explanatins followed by exercise sessions.
