Compared to “classic” Bluetooth, BLE is intended to significantly reduce power consumption and costs while maintaining a similar communication range. Bluetooth LE was initially introduced under the name Wibree by Nokia in 2006. It was merged into the main Bluetooth standard in 2010 with the adoption of version 4.0 of the Bluetooth Core specification. Mobile operating systems including iOS, Android, Windows Phone, and BlackBerry, as well as OS X and Windows 8, natively support Bluetooth Low Energy. The Bluetooth SIG predicts that more than 90% of Bluetooth-enabled smartphones will support the low energy standard by 2018. Figure 1: Bluetooth Low Energy 2.0 Bluetooth Low Energy Applications 2.1 WHERE - Bluetooth low energy technology can enhance devices such as watches, toothbrushes or toys with Bluetooth wireless technology. It also offers developers the ability to incorporate new features into devices already compatible with Bluetooth technology, such as sports & fit...... middle of paper ......3 ms8 Voice compatible No9 Topology of the Star-bus network10 Power consumption 0.01 to 0.5 (depending on use case)11 Peak current consumption <20 mA12 Service discovery Yes13 Profile concept Yes14 Data payload via (net) 100 kbps15 Robustness Strong16 Range 250 mTable 1: Bluetooth Low Energy Capabilities1) Bluetooth Low Energy is about state transfer• small, infrequent data bits• lowest possible power consumption• lowest latency2) splits the ISM band of 2.4 GHz in 40 channels• 3 advertising channels• 37 data channels• fn = 2402 + 2n MHz3) GFSK modulation• Modulation index 0.5, offering a better range than classic Bluetooth• allows the use of fewer channels Advertising • Reduces power consumption • Increases connection speeds • Can reuse existing RF components in a Bluetooth chip • Minimal additional cost in dual-mode chips
