Converged Communications
Wiley-IEEE Press (Verlag)
978-1-119-86750-0 (ISBN)
In Converged Communications: Evolution from Telephony to 5G Mobile Internet, 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. Converged Communications offers:
In-depth treatments of fixed telephone and transmission systems, including operation of telephone exchanges and signaling systems
Comprehensive explorations of data communication systems, including transmission of data over telephone lines and data network technologies, such as Ethernet and TCP/IP
Incisive discussions of mobile cellular systems, including GSM, 3G, LTE, VoLTE and 5G
Insightful analysis of incremental system evolution to justify various design choices made
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, Converged Communications: Evolution from Telephony to 5G Mobile Internet will also earn a place in the libraries of undergraduate and graduate students studying telecommunications and mobile systems.
Constructive comments and improvement proposals about Converged Communications or its online appendices can be sent by email to address converged.communications.book@gmail.com. The feedback will be considered for possible new editions of the book or the revisions of the appendices.
Erkki Koivusalo has worked at Nokia for over 20 years in a range of roles. He has extensive experience on fixed and mobile communications systems of various types. He is currently an Advisor at Sofigate in Helsinki, Finland, and helps clients for building complex IT systems.
