Advanced Wireless Networks : 4G/5G and beyond (AWN)

Description

Wireless Internet access is now widespread and with the deployment of 5G the use cases will generalize to various application domains. Whatever the type of radio access (wireless technologies such as Wi-Fi or cellular technologies such as 4G and 5G), fundamental problems arise: how to ensure good coverage, how to reuse the radio resource in time or space to flow a large traffic, how to share this radio resource between different user devices, how to allow a reliable transmission on an error-prone medium. Furthermore, the way to manage mobile and sporadic data flows as well as mobility is kept unchanged compared to previous generations. At the end of the course, the student will be able to explain the basic principles of radio interfaces and to analyse simple scenarios of flow setup or release and mobility of a terminal in a wireless network.
