BPL uses higher frequencies, a wider frequency range and different technologies from other forms of power-line communications to provide high-rate communication over longer distances. BPL uses frequencies which are part of the radio spectrum allocated to over-the-air communication services therefore the prevention of interference to, and from, these services is a very important factor in designing BPL systems. == Standards == Two BPL standards are: * The IEEE 1901 standard is usable by all classes of BPL devices, including BPL devices used for the first-mile/last-mile connection (<1500m to the premise) as well as in buildings for LANs, Smart Energy applications, transportation platforms (vehicle) applications, and other data distribution (<100m between devices). * The G.hn (Gigabit Home Networking) standards maintained by the ITU-T define networking over power lines, phone lines and coaxial cables for home networking applications 〔(【引用サイトリンク】title=Homegrid - About )〕 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「Broadband over power lines」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.
