【正文】 WLAN 是當(dāng)前移動(dòng)互聯(lián)網(wǎng)的熱點(diǎn)技術(shù)。論文文理流暢，有較為詳實(shí)的實(shí)例支撐相關(guān)理論，是一篇合格的畢設(shè)論文。無線網(wǎng)絡(luò)具有的部署靈活性、終端可移動(dòng)性、易擴(kuò)展性等技術(shù)特點(diǎn)，使無線網(wǎng)絡(luò)比傳統(tǒng)有線網(wǎng)絡(luò)具有更佳的經(jīng)濟(jì)效益，使無線網(wǎng)絡(luò)技術(shù)的應(yīng)用進(jìn)入高速發(fā)展階段。 關(guān)鍵詞： 無 線局域網(wǎng)；關(guān)鍵技術(shù)；協(xié)議體系 II Principle and design of WLAN Abstract With the rapid development of WLAN technology in recent years,wireless work is applied widly for its flexible disposition,terminal removability and expansibility. The paper first describes the historical background of the development of WLAN technology,followed by the introduction of WLAN position principle,working principle, key technology and protocol architecture,finally take the Zhongshan Uni office building WLAN construction project as an example,the paper proposed a WLAN solution that helps the implementation of wireless work project.
