蓝牙技术的面世以来一直倍受关注,经过不断发展的蓝牙技术,已经越来越接近我们的生活。蓝牙技术使用2.402～2.480GHz 的 ISM(In dus-trial Seientific And Medical、工业、科学和医疗)频段,这个频段的特点是不需要申请使用许可证,其工作中心频率在2.45GHz,采用全双工工作模式,设备可以同时接收和发送数据。在发射频率为1MHz 时,数据速率最高可达721kbps。蓝牙在设计时就考虑到了语
Bluetooth technology has been the focus of attention since its introduction, through the continuous development of Bluetooth technology, has become more and more close to our lives. Bluetooth technology uses 2.402 ~ 2.480GHz ISM (In dus-trial Scientific and Medical) band, this band is characterized by no need to apply for a license, the frequency of its work center at 2.45GHz, the use of full-duplex Working mode, the device can receive and send data at the same time. At a transmit frequency of 1MHz, the data rate can be up to 721kbps. Bluetooth is designed with language in mind
