在個人的健康設備的藍牙解決方案

　　雖然專有Ant協(xié)議在為健康和健身設備提供低功耗通信框架方面起了主導作用，但藍牙低能量技術已經成為一個很有吸引力的替代方案。除了低功耗的要求外，可編程設計允許工程師利用市場上大量安裝的藍牙設備來創(chuàng)建新的和復雜的應用程序。對于工程師來說，是一件既可實現(xiàn)下降模塊為基礎的解決方案的供應商如blueradios，松下，和RFM，或部署自定義解決方案基于BLE芯片CSR德克薩斯文書。

　　半導體制造商還可以結合ICS中的可移植性和典型的藍牙功能，創(chuàng)建雙模或所謂的“藍牙智能就緒”，為低功耗無線設備提供前端解決方案。事實上，藍牙智能消費品（包括第三代iPad和幾乎所有新智能手機）的快速普及，為單模可編程的藍牙設備提供了現(xiàn)成的基礎。公司只需要開發(fā)合適的應用程序來將智能手機轉變成基站，以便使用低功率設備傳輸?shù)膶崟r數(shù)據進行實時健康監(jiān)視器和健身管理系統(tǒng)。

　　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.
