It is the first place I go when I need to look up something that I am unsure of or when I encounter a new or unfamiliar term. I have been using Telecommunications Essentials now for two years as the course text for business technology students taking Introduction to Telecommunications. My course covers the entire book and the students end up with a practical knowledge base of the components, technologies, and connectivity that make today’s networks work. This new edition is most welcome since it includes new advances in the areas of fiber optics, wireless, Voice over IP, and broadband technologies that have emerged since the publication of the first edition. This new edition will replace my well-worn copy of my first edition of Telecommunications Essentials, which has served me well so far.”
