802.11 Wireless Networks: The Definitive Guide

Front Cover
"O'Reilly Media, Inc.", 2005 - Computers - 630 pages

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.

About the author (2005)

Matthew Gast works in the Office of the CTO at Trapeze Networks, where he leads the development of open wireless network standards and their application to the Trapeze architecture. He is a member of the IEEE 802.11 working group, and serves as chair of 802.11 Task Group M. As chair of the Wi-Fi Alliance's Wireless Network Management marketing task group, he is leading the investigation of certification requirements for power saving, performance optimization, and location and timing services. Matthew also chairs the Security Technical task group, which is extending Wi-Fi protected Access (WPA) certification to incorporate newly-developed security mechanisms so that it remains the strongest form of protection available for Wi-Fi networking. In 2007, Matthew was a founder of the OpenSEA Alliance, a group organized to support the development of open-source network security solutions. He currently serves on the engineering steering committee, the organization's board of directors, and as its corporate secretary. Matthew's most recent book, 802.11 Wireless Networks: The Definitive Guide (O'Reilly Media), now in its second edition, is the top selling reference work in the field and has been translated into six languages.
