Bluetooth Technology and Application

蓝牙技术是近几年兴起的一种近距离无线通信的全球标准,具有广泛的应用前景.它具有低成本、近距离无线通信的功能,能取代有线电缆而建立通信设备之间的无线连接.本文讨论了蓝牙的技术规范;分析了底层硬件模块、中间协议层和高层应用框架等蓝牙协议结构;阐述了蓝牙空中无线接口单元、链路控制单元、链路管理和软件功能单元等功能模块的性能与网络技术;说明了蓝牙技术在近距离无线数字通信技术中的巨大应用潜力.

Bluetooth is a global standard for wireless connectivity in recent year, possessing extensive application foreground. Bluetooth is based on a low cost, short range radio. Bluetooth technology facilitates the replacement of the cables normally used to connect one device to another, with one universal short-range radio link. This paper discusses the bluetooth technology standards. It analyzes protocol stack such as the baseband layer, middle protocol stack, and high layer application frame. It describes the function blocks about radio unit, link control unit, link management and software function unit and networking technology in detail. Moreover, it shows the application potential of the bluetooth technology in short range radio communication.
