目前市場上的定位技術普遍採用WiFi、藍芽、3G/LTE 基地台等方式,大都使用訊號強度來判斷,僅能判斷距離而無法取得絕對定位,且誤差大約2-10 公尺。工研院無線通道狀態資訊定位系統,使用類似小型WiFi 基地台的WiFi AP 連線WiFi 手機,利用該無線通道的資訊進行定位,誤差值可縮短至1 公尺以內。此外,因手機不需安裝額外APP,不影響使用者的使用習慣及手機耗電量,只要手機正常連接基地台,該定位系統就能馬上追蹤手機位置,且一台WiFi AP 能進行多台WiFi 手機的位置追蹤。

應用與效益

以自我組織網路管理系統結合無線通道狀態資訊定位系統,提供室內精準定位功能,可應用於百貨賣場精準推播行銷或櫃位熱點統計、協助醫療院區掌握醫療物件及設備的位置,並即時追蹤醫療人員或患者位置等。此技術榮獲2018 年小型基地台論壇(Small Cell Forum, SCF)頒發評審團特別獎(JUDGES'CHOICE of the SCF Awards)。
