超宽带无线技术标准之争

The Argument of Standards of UWB

目前全球的宽带无线接入技术研究重点似乎已经向短距离传输技术转移。在WLAN和蓝牙技术逐渐成熟并走入商用市场的同时,对超宽带(UWB)无线传输技术的研究和产品研发投入在逐渐加大。本文在简要对UWB技术与其他短距离传输技术性能进行比较的基础上,对目前UWB技术标准化工作中两大阵营的纷争进行了介绍,最后分析了UWB技术的发展前景。

In recent years,the technology of UWB has been the focus of wireless access technology study group.This article compares the performance of several kinds of short distant transfer technology.On this base,it describes the argument of the group of UWB:MB-OFDM which MBOA support and DS-CDMA,supported by Motorola.The last part analyses the development of UWB technology and application market.
