Readers of this book should have an electrical engineering background but have not yet dealt with RFID. To this end, Dr. Dobkin is very careful to illustrate all concepts and detail his explanations meticulously. In this way he brings the reader along organically showing him/her what to expect, develop, and use while implementing an RFID system.

The book is easy reading for a someone with a solid background in electronics. Subject flow is very good. There are sufficient formulas in the book to allow the necessary calculations without bogging the reader down with calculus. A good algebra background is sufficient.
What really comes out in reading the book is the practical information on how to go about implementing a low power RF product. While the book is focused on RFID tags, the information would be very useful for someone who is researching ZigBee, RFCE, Bluetooth or any short range radio system. Modulation schemes are explained clearly as are the traditional RF circuits.
My background is embedded systems, general analog and digital circuit design. I was able to grasp and apply most of the information presented with a minimum amount of effort considering much of it is new. The one place where the book is lacking is in the explaination of how to use Smith Charts. There is a wealth of information available on the web to offset this minor flaw.
The book is well worth the cost and the time to read it. The subject is presented clearly enough that a non-technical manager would benefit from reading the book and would be able to understand in general terms what is technical staff is accomplishing. The CD has some videos showing the basic RFID protocols graphically that are not worth the time to watch.
