建築物的牆或是物件對於無線區域網路都有不同的影響。我們可以使用一個GUI的程式去分析這些路徑損耗。首先, 讀取一個建築物的 AutoCAD檔並給予各物件參數, 然後去計算Tx和Rx之間的路徑損耗。最後我們以Tx為中心去分析出一個Rx可接收訊號的最佳範圍。設計這個無線區域網路規劃之自動校準規劃工具的主要目的就是以預測估計的方法找出放置Rx的最佳位置。
The wall or object of the building has different effects on the path loss contour for wireless transmission. We can use a GUI program to analyze the path loss contour. Loading an AutoCAD files and giving the loss parameter, then we can calculate the path loss between Tx and Rx. For the wireless LAN, we calculate the path loss contour of the mobile users in the Ad Hoc network. In order to determine the good reception locations for the mobile user, we design this Site Survey Tool to find the optimal locations for the mobile users.
