在這裡，我們報告的信號強度上的文件傳輸和下載和上傳速度的影響進行實驗研究。我們使用一對筆記本電腦，一台iPad，在計算機中心和管理樓宇國立中央大學移動和TP-LINK無線接入點和結果它們之間做了一個對比進行了多次實驗。可以看出大信號覆蓋範圍和更高的下載和上傳速度在計算機中心的建設比管理建設。顯然，下載和上傳速度在所有的實驗地點迅速衰減距離接入點15米。視線堵塞的牆壁上發現有在的Wi-Fi鏈路吞吐量的顯著作用。;Here we report an experimental investigation of the impact of signal strength on the file transfer and download and upload speeds. We have conducted several experiments using a pair of laptops, an ipad, a mobile and tp-link access point at the computer center and management buildings at National Central University and a comparison of results is made between them. It is seen large signal coverage area and higher downloads and uploads speed at computer center building than management building. Apparently, the download and upload speeds at all the experimental locations decay rapidly within 15 meters from the access point. Line-of-sight blockage by the walls is found to have the significant effect on the Wi-Fi link throughput.
