Ultra-wideband communications for wireless personal area networks with low rate applications

点击翻译按钮获取中文摘要

This research proposal investigates enabling ultra-wideband (UWB) technologies for low rate wireless personal area networks (WPAN). Recently, UWB has been proposed in the IEEE 802.15.4a Working Group as a physical layer candidate for low rate, short range wireless networks. In the low rate application domain, UWB can easily achieve a transmission speed much higher than that of Bluetooth due to its large bandwidth. The primary features of UWB include low cost, long battery life, multipath immunity and the ability to have communications and simultaneous precision ranging capabilities. Overlaying with the frequency bands of existing radio systems, UWB allows more efficient use of the scarce spectrum resource. The intended applications include smart home and personalized services, consumer electronics, family communications/supervision of children, industrial and building automation, tracking and logistics, asset tagging and management, search and rescue, security, medical applications, and military applications, etc.
