White-Fi

(名詞) 透過電視頻寬未使用的空間來傳輸的無線網路。亦寫成 White FiWhiteFi。這個字是由 white + WiFi 拼綴而成。

註:White-Fi 的正式名稱為 802.11af,有時亦叫做 Super WiFi。相較於一般的 WiFi,White-Fi 的主要優點是,可以傳輸較遠的距離且擁有較佳的牆壁穿透力或穿牆力 (wall penetration),因此適合農村地區的無線傳輸。

New devices including smartphones, tablets, and computers that know how to detect unused spectrum can use it to transmit wireless broadband signals, also known as “WhiteFi” or “Super Wi-Fi.” These frequencies are especially useful because they can carry a lot of data over long distances and reach indoors.
