Campus environment the wireless local area network applications
Abstract: the popularity of campus network speed up the application of the network information exchange, cable network coverage is limited, the wiring fee higher some shortcomings have become increasingly apparent, and the cable network can't meet the teachers and students in the university campus in uncertain environment of network information use requirement, the wireless local area network technology can with its the unique advantages of effective to make up the insufficiency. Based on the campus uncertain environment, can be in teaching building, lounges, conference room, hall, auditorium, outdoor place, the digital library in the wireless network coverage area increased, make wireless network in campus environment that can be widely applicable.
Keywords: wireless LAN; Wireless access point; IEEE802.11 agreement; Not sure environment .

0. introduction
University network teaching, network conference, digital library, network storage technology and network laboratory application popularize continuously etc, portable computer, such as the wide application of mobile equipment, personnel liquidity increases, some area is not suitable for large-scale wiring, makes a wired LAN can't satisfy teachers and students wireless, mobile access campus network, at any time and place the Internet access requirements. The Wireless Local Area Network technology (Wireless Local Area Network) can effectively to make up the insufficiency. As a traditional LAN complement, can cover to cable network involved, meet in uncertainty environment use of network resources and sharing demand, in the campus network has a wide application prospects. At present, have wireless campus has become the sign of the informational network development.

校園環(huán)境下無(wú)線(xiàn)局域網(wǎng)的應(yīng)用

摘要： 高校校園網(wǎng)的普及加快了網(wǎng)絡(luò)信息交流的應(yīng)用，有線(xiàn)網(wǎng)絡(luò)覆蓋范圍有限、布線(xiàn)費(fèi)用高等一些缺點(diǎn)日益顯露，有線(xiàn)網(wǎng)絡(luò)不能滿(mǎn)足在校師生在校園不確定環(huán)境中對(duì)網(wǎng)絡(luò)信息的使用需求，無(wú)線(xiàn)局域網(wǎng)技術(shù)可憑借其獨(dú)有的優(yōu)勢(shì)有效的彌補(bǔ)這些不足?；谛@不確定環(huán)境，可在教學(xué)樓、自習(xí)室、會(huì)議室、報(bào)告廳、禮堂、室外場(chǎng)所、數(shù)字化圖書(shū)館中增加無(wú)線(xiàn)網(wǎng)絡(luò)覆蓋區(qū)域，使無(wú)線(xiàn)網(wǎng)絡(luò)在校園環(huán)境中能得到廣泛適用。

　　高校網(wǎng)絡(luò)教學(xué)、網(wǎng)絡(luò)會(huì)議、數(shù)字化圖書(shū)館、網(wǎng)絡(luò)存儲(chǔ)技術(shù)和網(wǎng)絡(luò)實(shí)驗(yàn)室等應(yīng)用不斷推廣，便攜式計(jì)算機(jī)等可移動(dòng)設(shè)備的廣泛應(yīng)用，人員流動(dòng)性增大，有些區(qū)域不適合大規(guī)模布線(xiàn)，使得有線(xiàn)局域網(wǎng)無(wú)法滿(mǎn)足在校師生無(wú)線(xiàn)、移動(dòng)接入校園網(wǎng)，隨時(shí)隨地接入Internet 的要求。無(wú)線(xiàn)局域網(wǎng)技術(shù)（Wireless Local Area Network）可以有效的彌補(bǔ)這些不足。作為傳統(tǒng)局域網(wǎng)的補(bǔ)充，能覆蓋有線(xiàn)網(wǎng)絡(luò)難以涉及的范圍，滿(mǎn)足不確定環(huán)境中網(wǎng)絡(luò)資源的使用和共享需求，在校園網(wǎng)中有很廣闊的應(yīng)用前景。目前，擁有無(wú)線(xiàn)校園網(wǎng)已經(jīng)成為高校信息化網(wǎng)絡(luò)化發(fā)展的標(biāo)志。
