This book provided an excellent overview of the very broad range of telecommunications topics, including history, telephone technologies, data technologies, protocols, and standards; from twisted-pair copper through fiber-optic, cellular, and satellite. It is a very quick read and a great introduction to anyone new to telecommunications. Its coverage is very good considering the broad range of topics covered.
It does not, however, provide much depth on any one technology. Most topics, such as ATM, SONET, etc., are covered in one to four pages each. It was significantly less than I was looking for, but I am still impressed with how well Ms. Dodd covered such a broad range of topics. Anyone with a high school education, no telecom experience, and the motivation to do it, could read and learn from this book.
