Summary: Big letdown
Review: This book was a huge disappointment to me. If the reader has any background in Telecommunications avoid this book.

The book reads well but the technologies mentioned lack depth and just skim the surface, barely mentioning topics at times. Explanations are repetitive and if the reader expects details stay away from this book.
