Course Overview:

This comprehensive seminar goes through the Architecture and Procedures of a Modern Cellular Network. 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 (GSM/UMTS evolution with some 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 4G evolution – reasons, technologies, network architecture & key challenges.

Who should attend?

Service providers, Network Equipment vendors, Value-added services developers, Regulators, Entrepreneurs and Everyone who seeks to better understand the cellular network

Prerequisities:
