Cellular Networks: From 2G to 5G

Course Highlights

This comprehensive seminar goes through the Architecture and Procedures of a Modern Cellular Network from 2G to 5G, with an emphasis being put on the network side. It covers RF Access aspects, as well as the Circuit & Packet Core Network aspects, and Value-Added-Services. The course mainly focuses on the 3GPP technologies evolution - GSM/UMTS/LTE -  yet with some details and comparison to the CDMA2000 world. It starts from cellular concepts, thru network architecture, and thru end-to-end processes (e.g. call setup, roaming voice/data , handovers, authentication…). The last chapter is dedicated to the 5G a new concept that will shape the next generation of mobile systems.  It will review the 5G cutting-edge technologies and architecture like heterogeneous networks, device-to-device communications as well as Internet of Things (IoT) solutions and virtualization methods like SDN and NFV.
