OpenSignal:全球手機無線網路地圖是一個收集了全球世界各個國家的手機基站、站(cell phone tower)、wifi接入點(Wi-Fi access points)的位置、訊號強度,以及各個運營商在不同地區的訊號覆蓋範圍。
OpenSignalMaps提供android客戶端用於資料採集,其採集方式和google類似。使用者安裝OpenSignalMaps Android客戶端後,程式即開始收集附近的基站id,訊號強度等資訊並上傳到OpenSignalMap。OpenSignalMaps彙總使用者上傳的資料,在Google Maps上以單個點或者熱點圖的方式顯示出來。
On this website we provide visualizations and analysis based on the data we’ve collected, including cellular coverage maps that show exactly how strong signal is in any particular area, as well as all the nearby towers for your carrier.
