I havn't read the whole book yet, but I use some parts of the material in function of my interests. This is an excellent practical book about a topic that is rarely developed in any book (if any) and that you have to learn the hard way. You receive directly real-life examples and real designs that you can apply in your RF engineer work. I recommend strongly this book. I know the book seems expensive, but you can acquire good knowledge in RF indoor design, which should ease your work. My only question is: when a book about tunnel RF design (with time dispersion explanation, ... another topic never developed in any books).
