802.11 Wireless Networks: The Definitive Guide [NOOK Book]

Overview

As we all know by now, wireless networks offer many advantages over fixed (or wired) networks. Foremost on that list is mobility, since going wireless frees you from the tether of an Ethernet cable at a desk. But that's just the tip of the cable-free iceberg. Wireless networks are also more flexible, faster and easier for you to use, and more affordable to deploy and maintain.The de facto standard for wireless networking is the 802.11 protocol, which includes Wi-Fi (the wireless standard known as 802.11b) and its...

Overview

As we all know by now, wireless networks offer many advantages over fixed (or wired) networks. Foremost on that list is mobility, since going wireless frees you from the tether of an Ethernet cable at a desk. But that's just the tip of the cable-free iceberg. Wireless networks are also more flexible, faster and easier for you to use, and more affordable to deploy and maintain.The de facto standard for wireless networking is the 802.11 protocol, which includes Wi-Fi (the wireless standard known as 802.11b) and its faster cousin, 802.11g. With easy-to-install 802.11 network hardware available everywhere you turn, the choice seems simple, and many people dive into wireless computing with less thought and planning than they'd give to a wired network. But it's wise to be familiar with both the capabilities and risks associated with the 802.11 protocols. And 802.11 Wireless Networks: The Definitive Guide, 2nd Edition is the perfect place to start.This updated edition covers everything you'll ever need to know about wireless technology. Designed with the system administrator or serious home user in mind, it's a no-nonsense guide for setting up 802.11 on Windows and Linux. Among the wide range of topics covered are discussions on:

  • deployment considerations
  • network monitoring and performance tuning
  • wireless security issues
  • how to use and select access points
  • network monitoring essentials
  • wireless card configuration
  • security issues unique to wireless networks
With wireless technology, the advantages to its users are indeed plentiful. Companies no longer have to deal with the hassle and expense of wiring buildings, and households with several computers can avoid fights over who's online. And now, with 802.11 Wireless Networks: The Definitive Guide, 2nd Edition, you can integrate wireless technology into your current infrastructure with the utmost confidence.

    Deceptive Title Page. Fails to cover 802.11(g), and very little on 802.11(a).

    This book deals with IEEE 802.11(b); the older and most likely soon obsolete standard. It mentions on the back outside jacket, 'In addition to the current 802.11(b) standard...also looks forward to the newest developments....802.11(a) and 802.11(g).'````````` Well, all it has on 802.11(g) is less than one page out of 443 pages, although this book was published in April 2002, and both 802.11(a) and (g) have now been approved, and product is available with 802.11(g).

    more difficult routing than for fixed Internet nodes

    [A review of the 2ND EDITION 2005] Some of you might bemoan the three years between this edition and the first, as a tremendous expansion of wireless networking has occurred in the interim. With the promise of far more to come. But as Gast explains, the rapid growth in usage and in the underlying standards made the writing of a comprehensive text difficult. Perhaps the biggest new topic in the book is the 802.11g. Unknown in 2002, its maximum bandwidth of 54 Mb/s has made it the most common wireless version in 2005's laptops. The book explains this and earlier standards, as well as the upcoming 802.11n, in the context of a common conceptual framework. Each improved upon its predecessors, but often carried forward common ideas. You probably have (or should have) some prior knowledge of TCP/IP and of its routing methods, for fixed Internet nodes. What you will find here is often rather more complex. The mobility of wireless nodes leads to a huge concomitant increase in the sophistication of the routing. Like a strange parallel universe of Internet protocols, if you will.
