Communications Systems and Networks

A comprehensive overview of today's networked world, offering just the right amount of technical detail.

Now updated to cover the latest wireless and broadband technologies, this lucid overview describes today's communications systems and networks–voice, data, video, and multimedia–and explains how they are likely to evolve and converge. Communications Systems and Networks delivers plain-English explanations of all the technical fundamentals–and puts everything in context by addressing standards, regulations, and the real-world outlook for legacy, contemporary, and emerging technologies. Whether you're a networking pro who wants to gain some perspective or you just want to understand our increasingly interconnected world, this is the one book you need to see the big picture.
