It's a very good book, it presents 3g concepts as well as other wireless networks. It has some practical examples, which makes complex concepts more clear. For a deep explanation of CDMA concepts and mathematics, you would need another book, but with this one you can get a more practical approach to CDMA. After reading this book, you would have a very precise idea of what is next in telecommunicactions. I think is a good book, though, is highly recommendable to also get UMTS and CDMA2000 specification, they are available for free.
