图书简介
How do modern communications networks operate? Why are those systems designed the way they are? In which ways are the newer systems better than their predecessors?  Telecommunications have evolved rapidly over the past 20 years, but how did A lead to B, and B to C?  What lessons can be learnt from what went before, and which technologies have managed to develop and evolve into what we now recognize as 5G and Beyond 5G? This book explains how communications systems evolved from fixed telephone networks to the latest 5G mobile systems optimized for packet switched Internet, but it is not merely a history book. The author, an expert in both IT and project management, describes major communications technologies deployed in the last decades, such as fixed telephone networks and its derivatives, (ISDN, V5, PDH, SDH); DSL access networks and WDM trunks; cellular radio access networks (GSM, GPRS, WCDMA, HSPA, LTE and 5G); Internet technologies (TCP/IP, IP routing and MPLS switching over Gigabit Ethernet); Voice and multimedia over IP systems (SIP VoIP, 3GPP IMS and VoLTE).  Anyone who has worked in these technologies, or on the periphery, will learn about the progress of modern communications.  The book will also be an essential reference for students on a range of communications courses.
