使用无线网络是一种获得解放的、自由的经历。但是在这种经历的背后存在着一个复杂的协议,并且当数据不只限于在物理线路上传输时,甚至会产生一些更为复杂的问题。怎样构造你的网络才能让移动式用户活动自如?怎样扩展无线网络才能让它在任何需要的地方都可用?无线网络会产生哪些安全问题?怎样把无线网络调整到最佳性能?怎样提供足够的容量来支持最初希望的用户?怎样处理更多的用户参与网络所带来的各种问题?
《802.11无线网络权威指南(影印版)》讨论了上述所有的问题及其他相关问题。本书主要是为部署或维护无线网络的严谨的系统管理员或网络管理员编写的。它讨论了802.11协议的工作原理,分析了各种可用选项的意义,以及排除故障的问题。书中广泛讨论了无线网络的安全问题,包括使用WEP标准的安全问题,并介绍了802.1x安全标准。由于对于任何严谨的网络管理员来说,网络监视都是一项基本的工作,并且适合无线应用的商用便携式探测器比较缺乏且价格昂贵,因此本书展示了怎样从Linux系统和公开的源代码软件创建无线便携式探测器。
除了当前的802.11b标准之外,本书还介绍了无线网络的最新发展,包括两个新的54 Mbps标准:802.11a和802.11g。书中还介绍了标准发展过程中的其他研究领域,包括改善访问点之间的移动性、服务质量、频谱管理和功率控制。
最后,本书向你展示了怎样配置无线卡和Linux、Windows和OS X系统,以及怎样处理访问点。很少有一本书能够把你需要掌握的理论和完成工作所需要的实际经验和建议有机地结合在一起。《802.11无线网络权威指南(影印版)》却是一本这样的好书。如果你负责管理无线网络,你就需要这本书。

Matthew S. Gast 曾协助各种组织了解无线网络技术,建设具有扩充性的、基于标准的安全无线局域网络。过去这几年,他自愿在 Interop Labs 担任工程师与讲师,他在那里与许多顶尖的工程师共事,学到了各种先进的网络安全协议并在研讨会中传达给其他与会者。Matthew 参加过的研讨会不计其数,范围横跨各大陆,他在研讨会上所连接过的无线网络比他在撰写本书第二版时所连接过的还多。他在加入目前所任职的无线局域网络系统公司之前,曾在数家网络安全公司工作过几年。
Matthew S.Gast is a renaissance technologist.In addition to his demonstrated expertise on a variety of network technologies,he is relentlessly inquisitive about the interconnected and interdependent world around him.After graduating from college,his interests in routing,security,and cryptography pulled him towards Silicon Valley to participate in scaling the mountainous network engineering challenge called the Internet.In addition to his technology interests,Matthew is a voracious reader on science and economics and a lifelong supporter of the scientific method.
Matthew is also a Registered Patent Agent before the United States Patent and Trademark Office.Patent agents assist in the drafting and prosecution of patent applications,which has been called the most demanding task in the United States legal system by the Supreme Court.Matthew has co-written two patent applications,one of which was for his own invention.
 
 
The animal on the cover of 802.11 Wireless Netowrks:The Definitive Guide is a horseshoe bat (Rhinolophus hipposideros ).This rare and globally endangered species is the smallest of the European horseshoe bats;they typically weigh only 4-10 grams and have a wingspan of 19-25 centimeters.Horseshoe bats get their name from the horseshoe-shaped,leaflike plate of skin around the nose.This nose-leaf helps modify and direct the ultrasonic sounds they emit through their nostrils (a method of sensory perception known as echolocation)to orient themselves to their surroundings,detect obstacles,communicate with each other,and find food.Bats' echolocation systems are so accurate that they can detect insects the size of gnats and objects as fine as a human hair.
Lesser horseshoe bats are found in a variety of habitats,ranging from the British Isles to the Arabian Peninsula and Central Asia,and from Morocco to Sudan.The lesser horseshoe bat was originally a cave-roosting bat,but many summer maternity colonies now occupy the roofs of old rural houses and farm buildings.These bats also sometimes roost in hedgerows and hollow trees.Maternity colonies of 30 to 70 are normal,but roosting mothers have been known to form colonies of as many as 200 bats.Lesser horseshoe bats hibernate,sometimes in large groups,from October until late April or early May.Their winter roosts are usually underground,in caves or tunnels.They hang by their feet with their wings wrapped around their bodies,often in open and exposed positions but rarely in large clusters.
