Bluetooth low energy (Bluetooth LE, BLE, marketed as Bluetooth Smart〔(Bluetooth Smart Technology: Powering the Internet of Things )〕) is a wireless personal area network technology designed and marketed by the Bluetooth Special Interest Group aimed at novel applications in the healthcare, fitness, beacons,〔(beacons )〕 security, and home entertainment industries.〔(bluetooth.com: Bluetooth Smart )〕 Compared to Classic Bluetooth, Bluetooth Smart is intended to provide considerably reduced power consumption and cost while maintaining a similar communication range. Bluetooth Smart was originally introduced under the name Wibree by Nokia in 2006.〔(HowStuffWorks.com: Wibree )〕 It was merged into the main Bluetooth standard in 2010 with the adoption of the Bluetooth Core Specification Version 4.0. Mobile operating systems including iOS, Android, Windows Phone and BlackBerry, as well as OS X, Linux, and Windows 8, natively support Bluetooth Smart. The Bluetooth SIG predicts that by 2018 more than 90 percent of Bluetooth-enabled smartphones will support Bluetooth Smart.〔(【引用サイトリンク】title=Mobile Telephony Market )〕 == Compatibility == Bluetooth Smart is not backward-compatible with the previous (often called "Classic") Bluetooth protocol. The (Bluetooth 4.0 specification ) permits devices to implement either or both of the LE and Classic systems. Bluetooth Smart uses the same 2.4 GHz radio frequencies as Classic Bluetooth, which allows dual-mode devices to share a single radio antenna. LE does, however, use a simpler modulation system. 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「Bluetooth low energy」の詳細全文を読む スポンサード リンク
