无线USB原理及其发展

USB—IF（USB Implementers Forum，USB执行论坛）推出的无线USB技术是第一个高速的无线个人接口，它使无线技术的自由性、柔韧性和有线USB技术的易用、高速和安全性有机结合起来，具有高速率、低功耗、便携性和允许多设备并发传输的特点。论述了无线USB的特点，无线USB体系的拓扑结构、数据流模型、USB总线调度和无线USB针对无线平台的加强技术，包括物理接口技术、电源管理方式、相联和安全机制和线缆适配器。随着无线USB技术的发展，它将在计算机工业、消费电子、移动通信等领域发挥巨大的作用，并有取代USB2．0的趋势。

Principles and its development of wireless USB

The wireless USB released by the USB Implementers Forum(USB-IF) is the first high-speed perso-(nal) interconnect technology that combines the freedom and flexibility of wireless technology with the ease of use,high speed and security of wired USB and it has the characters of high speed,low power consumption,easy use and allowing exchange data at the same time.This paper dissertates the characters of wireless USB and topology,data flow models and USB schedule of the architecture of wireless USB,including the enhanced technology that deve-loped for wireless platform by wireless USB,just such as the physical interface,power management,device association and security,wire adapter.With the development of wireless USB,it will have an important role in PCs and PC peripherals,consumer electronics and mobile devices,and it will have the trend to replace USB2.0.
