从以前的单机操作,到现在网络技术的高速发展,电脑自动化和电脑网络正是在不经意中改变着人类的生活,使世界越来越小。蓝牙技术就是在这样的发展趋势下产生的。蓝牙技术是一种无线数据与语音通信的开放性全球规范,它以低成本的近距离无线连接为基础,为固定与移动设备通信环境建立一个特别连接,其程序写在一个9×9(mm)的微芯片中。蓝牙设备好似一个万能遥控器,它发出的信号可以在一定范围内穿墙走壁,将传统电子设备的一对一的连接变为一点对多点的连接。蓝牙将改变人们的生活蓝牙设备使用全球通行的、无需申请许可的2.45GHz频段,可实时进行数据和语音传输(传输速率可达到10Mbps,在支持3个话音频
From the previous stand-alone operation to the rapid development of network technology, computer automation and computer networks have inadvertently changed human lives and made the world smaller and smaller. Bluetooth technology is generated under such a trend. Bluetooth is an open global specification for wireless data and voice communications. It is based on a low-cost, close-proximity wireless connection that establishes a special connection between the fixed and mobile communications environment. The program is written in a 9 × 9 (mm) ) Microchips. Bluetooth device is like a universal remote control, the signal it sends can walk through the wall within a certain range, the traditional one-to-one connection of electronic devices into a point to multipoint connection. Bluetooth will change people’s lives Bluetooth devices using the worldwide prevalence of 2.45GHz band without permission, real-time data and voice transmission (transfer rate up to 10Mbps, in support of three voice
