OVERVIEW

The class aims at deepening the knowledge of the main architectural aspects and protocols at the basis of the Wireless Networks. It is essentially organized in five parts, addressing a general introduction to wireless communications, WiFi (IEEE 802.11) networks,  Bluetooth, the cellular radio-mobile networks (starting from the second (GSM) up to the fourth generation (LTE)), and a short summary about the mobility management issue and an overview on the 5thgeneration (5G) mobile networks.

AIMS AND CONTENT

LEARNING OUTCOMES

Provide a framework for all major network technologies that use wireless (wireless) transmissions considering application areas and architectures both from a structural and protocollary point of view. • Deepen some specific technologies of particular interest and Present and future diffusion, such as wireless networks and wireless LAN networks • Provide introductory indications to identify the current and short-term utilization possibilities of the above-mentioned technologies in relation to the various application areas. • Outline the main solutions to the mobility problem on packet networks (in TCP / IP technology) in relation to the wireless technologies described.

AIMS AND LEARNING OUTCOMES

In more detail, the course aims to provide knowledge and insight on the following topics. Introduction to architectures with the classification of wireless networks in mobile cellular systems, technologies for wireless local area networks (LAN) and Personal-Sensor-Body Area Networks (PAN, SAN, and BAN). Specification of cellular mobile radio networks from the second generation (2G-GSM) and evolutions (GPRS and EDGE), to move to the third generation (3G-UMTS) and finally to the fourth (4G, LTE). The standard for IEEE802.11 (Wi-Fi) WLAN networks, described in all its evolutions starting from version 11b up to version 11ac. Personal communications through the Bluetooth standard, including the latest variants like Bluetooth low-power. A summary of the technologies for managing mobility. An overview of the newest evolution of mobile radio networks in the standardization phase: the fifth generation (5G) of the cellular network. The result of learning is to give the student, oriented to a specific field of Engineering, the ability to understand the different technologies of wireless networks and make effective design choices that provide for their use.
