在个人的健康设备的蓝牙解决方案
虽然专有Ant协议在为健康和健身设备提供低功耗通信框架方面起了主导作用，但蓝牙低能量技术已经成为一个很有吸引力的替代方案。除了低功耗的要求外，可编程设计允许工程师利用市场上大量安装的蓝牙设备来创建新的和复杂的应用程序。对于工程师来说，是一件既可实现下降模块为基础的解决方案的供应商如blueradios，松下，和RFM，或部署自定义解决方案基于BLE芯片CSR德克萨斯文书。
半导体制造商还可以结合ICS中的可移植性和典型的蓝牙功能，创建双模或所谓的“蓝牙智能就绪”，为低功耗无线设备提供前端解决方案。事实上，蓝牙智能消费品（包括第三代iPad和几乎所有新智能手机）的快速普及，为单模可编程的蓝牙设备提供了现成的基础。公司只需要开发合适的应用程序来将智能手机转变成基站，以便使用低功率设备传输的实时数据进行实时健康监视器和健身管理系统。
The BLE standard was created specifically to reduce power consumption. Using a connectionless protocol， BLE devices establish very fast connections and use quick bursts to transfer small amounts of data during each connection （Figure 1）。 Maximum power consumption is a few milliamps with typical standby power consumption in the microampere range. Furthermore， BLE devices can be put into sleep mode and quickly reawakened to complete these quick bursts of activity. The result is a low-power communications solution that consumes about 10 percent of the power required for Classic Bluetooth designs. As a result， a coin-cell battery， such as those commonly used in heart rate monitors （HRM） or other health equipment， can power a BLE peripheral device for months and even years.
