Converged Communications: Evolution from Telephony to 5G Mobile Internet

In , telecommunications industry veteran Erkki Koivusalo delivers an essential reference describing how different communications systems work, how they have evolved from fixed telephone networks to the latest 5G mobile systems, and how the voice and data services converged. The central theme of the book is to build deeper understanding about incremental technological progress by introducing both state of the art and their predecessor technologies. The book explores four main areas, including fixed telephone systems, data communication systems, mobile cellular systems, and IP multimedia systems. It clearly explains architectures, protocols, and functional procedures, and discusses a variety of topics ranging from physical layer processes to system level interactions. offers: The book is supported with extensive online appendices, which covers communication system concepts, an overview of standardization, various technologies used in the past, state-of-the art technologies such as WLAN, cable modems, and FTTx, complementing the other systems described in the book which have evolved from the fixed telephone network. Perfect for network operators, system integrators, and communication system vendors, will also earn a place in the libraries of undergraduate and graduate students studying telecommunications and mobile systems.
