基于超宽带(UWB)技术构建短距离无线通信网络的研究及应用

Research and Application of Short Distance Wireless Communication Network Based on Ultra-wideband (UWB) Technology

随着无线通信技术的发展,人们对短距离内超带宽、高速数据传输的要求越来越高。超宽带(UWB)技术的出现满足了这些需求,它具备其他无线通信技术所无法具有的宽带宽、高速数据传输、功耗低、安全性能高等特点。本文比较了UWB与目前使用较为广泛的IEEE 802.11n、Bluetooth、HomeRF等其他短距离无线通信技术,分析了UWB的应用前景。

With the development of wireless communication technology, people＇ s requirement for ultra bandwidth, high speed data transmission in short distance is higher and higher. The emergence of ultra wideband （UWB） technology meets these requirements for it has the features of wide bandwidth, high speed data transmission, low power consumption, safety, etc, which other wireless communications technology does not have. The basic principle of UWB signal model and the technical features, and combine UWB with the wider use of short distance wireless communication technologies of IEEE 802. l ln, Bluetooth, HomeRF are compared, and finally the application prospect of UWB is analyzed.
