Learning Objectives
The course presents the main issues and design aspects for standards 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, the students will gain solid academic knowledges 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 architectures, to analyse and design in the 4G, 5G networks and the Internet of Things (IoT) context.
Prerequisites
Basic knowledges of main numerical modulations, channel coding techniques, network protocols
Teaching Methods
Classroom lectures, laboratory experiences and seminars on specialized topics also held by experts from the world of industry.
There are agreements for conducting visits and internships at TIM laboratories in Italy and SMEs in the IoT sector

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.
