| New book explores 'promises and pitfalls' of wireless networks |
May 08, 2002
Sebastopol, CA -- (press release excerpt) -- 802.11 technology goes by a variety of names, depending on who is talking about it. Some people call it wireless Ethernet to emphasize its shared lineage with traditional wired Ethernet. Wi-Fi, from wireless fidelity, is another popular name, referring to a certification program run by the Wireless Ethernet Compatibility Alliance (WECA). Any 'wireless' vendor can have its product tested for interoperability, and equipment that passes can use the Wi-Fi mark. But those who work hands-on with the technology call it simply 802.11. In his new book, 802.11 Wireless Networks: The Definitive Guide (O'Reilly, US $44.95), author Matthew S. Gast delves into the intricacies of wireless networks, revealing how 802.11 technology can be a practical and even liberating choice for businesses, homes, and organizations. At the same time, he leads the reader through all aspects of planning, deploying, and maintaining a wireless network, and covers the security issues unique to this type of network.
The adoption of 802.11 wireless technology is moving at an explosive rate. With transfer speeds of up to 11 Mbps, it's the fastest practical wireless technology approved by the FCC for low-power unlicensed use. The obvious dvantage of wireless technology is mobility--it frees users from the tether of an Ethernet cable at a desk. Wireless networks also offer flexibility, which translates into rapid deployment--adding a new user to a wireless network does not involve running cables, punching down terminals, and patching in a new jack. '802.11 Wireless Networks: The Definitive Guide' covers everything the reader will need to know to understand and use this technology.
'802.11 Wireless Networks: The Definitive Guide' discusses how the 802.11 protocols work, with a view towards understanding which options are available and troubleshooting problems that arise. It contains an extensive discussion of wireless security issues, including the problems with the WEP (Wired Equivalent Privacy) standard and a look at the 802.1x security standard. Since network monitoring is essential to any serious network administrator, and commercial packet sniffers for wireless applications are scarce and expensive, the book shows how to create a wireless packet sniffer from a Linux system and open source software.
Gast tackles these issues and many more in his book. '802.11 Wireless Networks: The Definitive Guide' also looks forward to the newest developments in wireless networks, including the two new 54 Mbps standards: 802.11z and 802.11g. It surveys other efforts moving through the standards track, including work to facilitate mobility between access points, quality of service, spectrum management, and power controls.
"802.11 Wireless Networks: The Definitive Guide" shows readers how to configure wireless cards and Linux, Windows, and OS X systems. Written for the serious system or network administrator who is responsible for deploying or maintaining a wireless network, this book is truly the definitive guide on wireless networking.
Note:
Chapter 15, '802.11 Network Deployment', is available free online.
