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 Networks: 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 Networks: The Definitive Guide is worth its weight in gold.

Amazon.com Review

Among network designers and administrators, wired Ethernet is a known quantity. Plenty is known about how to build good twisted-pair network infrastructures, how to keep them secure, and how to monitor their excess capacity. Not so for the wireless Ethernet networks (built around the IEEE 802.11x standards)--these hold much more mystery for even experienced network designers. 802.11 Wireless Networks: The Definitive Guide aims to codify the body of knowledge needed to design and maintain wireless local area networks (LANs). The authors succeed admirably in this, covering what installation and administration teams need to know and digging into information of use to driver writers and others working at lower levels.

The only significant detail that's been excluded has to do with security--a notorious weak point of 802.11x LANs. The authors cover the feeble but widely used Wired Equivalent Privacy (WEP) authentication protocol in detail and devote another whole chapter to 802.1x, which is an emerging authentication scheme based on Extensible Authentication Protocol (EAP). The author has considerable skill in communicating information graphically and does a great job of using graphs to show how communications frequencies shift over time and how conversations among access points and network nodes progress over time. This is indeed an authoritative document. --David Wall

Topics covered: How IEEE 802.11a and 802.11b wireless networks (also known as WiFi networks) work, and how to configure your own. The framing specification is covered well, as are authentication protocols and (in detail) the physical phenomena that affect IEEE 802.11x radio transmissions. There's advice on how to design a wireless network topology, and how to go about network traffic analysis and performance improvement.

Review

'Building Wireless Community Networks is an enthusiastic introductory guide to a technology which can really be put to use to change people's lives. Wireless gives the power of the network back to the people, and this book helps to demystify the technology and enable any community to take control.' Linux User, March/April (Classic Title)

Essential for wireless students and profesionals.

Bymatton September 23, 2016

Format: PaperbackVerified Purchase

This edition is out of date, I see an updated version will be released early 2017 and I plan to buy it when it comes out. I'm studying for the CWNA exam and this text complimented very helpfully the official study guide. What the CWNA didn't make clear, this text fille din those blanks and even exceeded the course content by providing the minutia of the 802.11 process.

I learned everything about 802.11 off this book!

ByAmazon Customeron June 22, 2016

Format: PaperbackVerified Purchase

This book I bought when I knew nothing about Wireless Networks. It taught me valuable skills i use in my job. I'll have to give this book 5 out of 5. It is written good. I could understand it unlike other computer books! This is one of the best on books on 802.11! I recommend it!

the book stops at 2005

ByGordon Redthornon February 27, 2013

Format: Kindle EditionVerified Purchase

it's mostly about packet structure and encryption packets. It is most useful if you moving from all wired tech to wireless and want an overview. the next book on 802.11n is probably more useful since most of the information in this book is out of date due to the rapid pace of technology changes.

This book serves as a good overview of 802

Bycjon April 30, 2015

Format: PaperbackVerified Purchase

This book serves as a good overview of 802.11. It is a good resource for a beginner who has little understanding of Wi-Fi and wants to know the lay of the land. For the experts this material might sound very basic and not interesting.

Great book if you want to have a general view of the wifi standard. It helped me as a reference for wifi configuration of several big home networks.

Best Single Book for Learning About Wireless Networks

ByM. Grahamon May 20, 2005

Format: PaperbackVerified Purchase

My company specializes in wireless security, cryptologic consulting and computer forensics, and this book (and its predecessor) are required reading for all of our staff. While not as technical as some of the Planet 3 books for their CWNA, CWSP and CWAP, it covers 90%+ of all the information a wireless network administrator or technician needs.

The only problem with any book of this type is how rapidly the technology changes. The first edition of this book, published in 2002, was out of date within a year or two. During that time, however, it was the best single source of information for the non-technical to moderately technical reader.

Buy it!

Very good, but dated

ByR. Smithon May 12, 2007

Format: PaperbackVerified Purchase

This book is a very detailed and mostly thorough description of 802.11 wireless networking. The author clearly describes the protocols and how they are typically used, plus various wireless network topologies, and even information about deployment such as antenna types.

Where the book falls short is that it was clearly written before the growth in popularity of "wireless controllers" or "wireless switches", and the auther says almost nothing about them or how wireless networking works when using a wireless-controller-based network.

There also was not much information about wireless network management, although that might be beyond the scope of this book.

Haven't read it.

I looked it over,and seems to cover any information you would need on WI-FI up though 802.11 n. I will most likely use this as a reference.
