 Slides are available on Moodle platform
The course presents to the student the standards, main issues and design aspects of mobile cellular networks, local wireless networks and sensor networks. It is aimed primarily, but not exclusively, for students of Master Degree in Telecommunication, Electronic Engineering and Information Engineering. Through the topics discussed, we will gain solid academic understanding of standards for cellular networks, WLANs and sensor networks, and specific skills in designing wireless system networks at system level. After completing the course, the student will have the ability to compare various wireless architecture, to analise and design in the 4G, 5G and Internet of Things (IoT) contexts.
Type of Assessment
The exam provides an oral interview on the topics of the program. More specifically, the exam tests the knowledge about: - the general principles how the different phenomena in mobile radio channels have to be taken into consideration in the design of a reliable radio communication link and performance of a radio link;
- the design of planning and of the load and capacity of basic cellular network configurations ;
- the general architecture and main elements and functionalities of a cellular mobile communication system, in GSM, UMTS/HSPA, LTE , 5G and beyond 5G networks;
- the physical layer and MAC layer for IEEE 802.11 family standards;
-the physical layer and MAC layer for IEEE 802.15.3 and IEEE 802.15.4.
