Fairly outdated now, this book was a great coverage of how wireless networking and Linux systems merge. The book explains wireless chipsets, how to use Windows drivers on Linux, how to access core features for certain chipsets, how to secure a wireless network, and how to invisible capture wireless information. This was useful for security professionals who want to learn more about wireless systems, however, the technology and protocols have changed and improved so much that a lot of the specifics are as irrelevant as learning about your ten year old computers memory slot.
