802.11 Wireless Networks: The Definitive Guide: Creating and Administering Wireless Networks

by Matthew S. Gast

As a network administrator, architect, or security professional, you need to understand the capabilities, limitations, and risks associated with integrating wireless LAN technology into your current infrastructure. 802.11 Wireless The Definitive Guide provides all the information necessary to analyze and deploy wireless networks with confidence.Over the past five years, the world has become increasingly mobile. Traditional ways of networking have altered to accommodate new lifestyles and ways of working. Wireless networks offer several advantages over fixed (or wired) networks, with mobility, flexibility, ease and speed of deployment, and low-cost at the top of the list. Large productivity gains are possible when developers, students, and professionals are able to access data on the move. Ad-hoc meetings in the lunch room, library, or across the street in the café allow you to develop ideas collaboratively and act on them right away. Wireless networks are typically very flexible, which can translate into rapid deployment. Once the infrastructure is in place, adding new users is just a matter of authorization.After a general introduction to wireless networks, this practical book moves quickly into the gory details of the 802.11 standard. If you ever need to debug a wireless network that isn't working properly, you'd better understand this material. 802.11 MAC (Media Access Control), detailed 802.11 framing, WEP (Wired Equivalent Privacy protocol), 802.1x, management operations, and the PCF (point coordination function) are all covered in detail. Author Matthew Gast also supplies impressive detail on the physical layers.As for getting a wireless network up and running... Gast offers clear, no-nonsense guide for using 802.11 on Windows and Linux, using and selecting access points, making deployment considerations, and seeing to 802.11 network monitoring and performance tuning. In the final section of the book, he summarizes the standardization work pending in the 802.11 working group.If you're looking for one book that provides a full spectrum view of 802.11, from the minute details of the specification, to deployment, monitoring, and troubleshooting, 802.11 Wireless The Definitive Guide is worth its weight in gold.

[Stephen]

This is a first rate book from O'Reilly. Plenty of depth, to the point that there will be little need to buy any other book on the subject. Here you will learn all about the physical layer, the 802.11 protocol, and plenty of information on the alphabet soup that surrounds it.

The guide is readable and logically laid out. It will make a great reference work but can be read through as a single whole too.

Though old enough to witness how much the 802.11 evolved since 2002, the book stays incredibly useful. The parts we know changed (802.11i, WEP) are causiously explained as well as the why of their weaknesses. A must-read that age as only improved, and a good introduction to its most recent edition!

[Kam Yung Soh]

A must-read if you want to dig into the internals of the IEEE 802.11 (WiFi) standard.
