Description
In today's competitive and fast-changing telecom industry, most professionals find themselves in the difficult situation of having to sacrifice keeping on top of the latest technology because they are striving to meet another round of high-pressure deadlines. Essentials of Modern Telecommunications Systems offers you a solution to this problem, helping you quickly coming up to speed with the latest advances in your field. By cutting out arcane mathematics and management-speak jargon, it focuses on the essentials you need for rapidly understanding and mastering the latest implementation and development techniques. It provides the complete systems picture from semiconductors to end-to-end networking. Covered are such cutting-edge technologies as Next Generation Wireless, VoIP, optical transmission, and digital subscriber loop, as well as other broadband technologies. Special attention is given to systems software, especially applications software for 3G products. Throughout the book, the emphasis is on techniques you can use on the job for modeling, testing, and system management. By relating advanced technology to current technology already deployed, this book lets you quickly go from the familiar and the everyday to the cutting edge and the future.
