摘要(中) 近年來, 由於 802.11b 規範的確定,加上許多廠商的共同努力之下,無線網路的應用己經十分的廣泛了,透過簡易的安裝,即能建置一個完整的應用無線網路技術的網路環境,使用於學習科技的應用也越來越廣,目前我們已將無線網路環境與設備帶入合作學校內,讓他們在課堂內能更善加利用網路資源,使課堂上能用資源更加豐富。在利用無線網路的環境,將無線電腦設備帶入學校內,但是在不同的合作學校進行課程時並非都能夠順利進行,由於在各種不同的無線網路環境之下所產生的問題並不明確,作者就在這些合作學校中取得數據並加以分析且盡量找出問題,所以利用了一些軟體來擷取這個無線網路環境下的網路封包與狀況,以實際的顯示出所遇到的問題,並且加以分析希望對於教室內的無線網路環境問找出適合的方案,以供課程順利的進行。
摘要(英) In recent years, because establish 802.11 of standard and the mass production of many manufacturers, wireless network application through very extensive. Want through the simple gearing only, we can build a wireless network environment. And the usage is also more wide and more wide in the application of the learning technology. We have brought the environment of wireless network and equipments to enter school the school at the present time. Hope to let them be able to even make something of the network resource in classroom, make classroom up can use the resource more abundant.
But physically at the time of different school inside usage wireless netowrk environment, not smooth. Because under various different environments, also cause the problem produced unknown indeed. So I would be use of some softwares to understand the actual network condition, And by obtain the data in these schools to make the analysis and find to go wrong t to help the system to debug. And find fit project of improvement wireless in the classroom network environment problem. Let teacher can teach smoothly in DCE V3.
