　　使用無(wú)線網(wǎng)絡(luò)是一種獲得解放的、自由的經(jīng)歷。但是在這種經(jīng)歷的背后存在著一個(gè)復(fù)雜的協(xié)議，并且當(dāng)數(shù)據(jù)不只限于在物理線路上傳輸時(shí)，甚至?xí)a(chǎn)生一些更為復(fù)雜的問(wèn)題。怎樣構(gòu)造網(wǎng)絡(luò)才能讓移動(dòng)用戶活動(dòng)自如？怎樣擴(kuò)展無(wú)線網(wǎng)絡(luò)才能讓它在任何需要的地方都可用？無(wú)線網(wǎng)絡(luò)會(huì)產(chǎn)生哪些安全問(wèn)題？怎樣把無(wú)線網(wǎng)絡(luò)調(diào)整到最佳性能？怎樣提供足夠的容量來(lái)支持最初希望的用戶？怎樣處理更多的用戶接入網(wǎng)絡(luò)所帶來(lái)的各種問(wèn)題？.《802.11無(wú)線網(wǎng)絡(luò)權(quán)威指南》第二版討論了上述所有問(wèn)題及其他相關(guān)問(wèn)題。本書(shū)主要是為部署或維護(hù)無(wú)線網(wǎng)絡(luò)的嚴(yán)謹(jǐn)?shù)南到y(tǒng)管理員或網(wǎng)絡(luò)管理員編寫(xiě)的。書(shū)中廣泛討論了無(wú)線網(wǎng)絡(luò)的安全問(wèn)題，包括使用WEP標(biāo)準(zhǔn)的安全問(wèn)題，并討論了動(dòng)態(tài)WEP和802.1X、802.11i安全標(biāo)準(zhǔn)。由于對(duì)于任何嚴(yán)謹(jǐn)?shù)木W(wǎng)絡(luò)管理員來(lái)說(shuō)，網(wǎng)絡(luò)監(jiān)視都是一項(xiàng)必須的工作，因此本書(shū)有專門(mén)的章節(jié)闡述如何使用Ethereal及其他工具進(jìn)行網(wǎng)絡(luò)分析和排錯(cuò)。..《802.11無(wú)線網(wǎng)絡(luò)權(quán)威指南》同時(shí)還介紹了無(wú)線網(wǎng)絡(luò)的最新發(fā)展。除了802．11b和11a標(biāo)準(zhǔn)之外，本書(shū)同時(shí)涵蓋802．11g，并前瞻了正在成為標(biāo)準(zhǔn)的802.11n協(xié)議。這個(gè)新的版本擴(kuò)展了網(wǎng)絡(luò)規(guī)劃架構(gòu)的討論，并特別關(guān)注了訪問(wèn)點(diǎn)之間的移動(dòng)性、頻譜管理和功率控制。本書(shū)是目前唯一的講述了如何衡量無(wú)線網(wǎng)絡(luò)性能及如何調(diào)整網(wǎng)絡(luò)到最佳性能的工具書(shū)。最后，《802.11無(wú)線網(wǎng)絡(luò)權(quán)威指南》展示了怎樣配置無(wú)線網(wǎng)卡和Linux、Windows和MAC OS X系統(tǒng)，以及怎樣處理訪問(wèn)點(diǎn)。很少有一本書(shū)能夠把你需要掌握的理論和完成工作所需要的實(shí)際經(jīng)驗(yàn)和建議有機(jī)地結(jié)合在一起。《802．11無(wú)線網(wǎng)絡(luò)權(quán)威指南》就是這樣的一本好書(shū)。如果你負(fù)責(zé)管理無(wú)線網(wǎng)絡(luò)，你就需要這本書(shū)。Matthew S.
