1) How Secure Is Your Wireless Network?
How Secure Is Your Wireless Network? provides detailed coverage of the available wireless protocols and the pitfalls of each (like interference with common household devices such as cordless phones and baby monitors).

2) Building Secure Wireless Networks With 802.11
The authors of this book have extensive first-hand knowledge of the technology and concepts they write about. The problem is that if your network traffic is flying through the air to your wireless networked computers, it can also be intercepted by unintended recipients. If you are going to delve into the world of wireless networking, you should read this book to learn how to do so securely.

3) Hack Proofing Your Wireless Network
Hack Proofing Your Wireless Network is an invaluable resource for implementing or administering a wireless network. The case studies, Security Alerts, FAQ's and other features of this book all help to provide a comprehensive, must-read book on wireless network security. If you are new to the concept this book is written in a way that you will understand. This book also makes a great reference.
