　　在個(gè)人的健康設(shè)備的藍(lán)牙解決方案

　　雖然專有Ant協(xié)議在為健康和健身設(shè)備提供低功耗通信框架方面起了主導(dǎo)作用，但藍(lán)牙低能量技術(shù)已經(jīng)成為一個(gè)很有吸引力的替代方案。除了低功耗的要求外，可編程設(shè)計(jì)允許工程師利用市場(chǎng)上大量安裝的藍(lán)牙設(shè)備來創(chuàng)建新的和復(fù)雜的應(yīng)用程序。對(duì)于工程師來說，是一件既可實(shí)現(xiàn)下降模塊為基礎(chǔ)的解決方案的供應(yīng)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(dǎo)體制造商還可以結(jié)合ICS中的可移植性和典型的藍(lán)牙功能，創(chuàng)建雙?；蛩^的“藍(lán)牙智能就緒”，為低功耗無線設(shè)備提供前端解決方案。事實(shí)上，藍(lán)牙智能消費(fèi)品（包括第三代iPad和幾乎所有新智能手機(jī)）的快速普及，為單?？删幊痰乃{(lán)牙設(shè)備提供了現(xiàn)成的基礎(chǔ)。公司只需要開發(fā)合適的應(yīng)用程序來將智能手機(jī)轉(zhuǎn)變成基站，以便使用低功率設(shè)備傳輸?shù)膶?shí)時(shí)數(shù)據(jù)進(jìn)行實(shí)時(shí)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.
