翻訳と辞書　辞書検索 [ 開発暫定版 ] スポンサード リンク Ambient backscatter ： ウィキペディア英語版 Ambient backscatter Ambient backscatter uses existing radio frequency signals, such as radio, television and digital telephony, to transmit data without a battery or power grid connection. Each such device uses an antenna to pick up an existing signal and convert it into tens to hundreds of microwatts of electricity. It uses that power to modify and reflect the signal with encoded data. Antennas on other devices, in turn, detect that signal and can respond accordingly. Initial implementations can communicate over several feet of distance, even with transmission towers up to away. Transmission rates were 1k bits per second between devices situated apart inside and apart outside, sufficient to handle text messages or other small data sets. Circuit sizes can be as small as 1 sq. mm.〔 This approach would let mobile and other devices communicate without being turned on. It would also allow unpowered sensors to communicate, allowing them to be placed in places where external power cannot be conveniently supplied. ==See also== *Internet of things 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Ambient backscatter」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
