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

本研究计划探讨为低速率无线个人区域网路（WPAN）启用超宽频（UWB）技术。最近，超宽带在IEEE 802.15.a工作组中被提出作为低速率、短距离无线网络的物理层候选。在低速率应用领域，UWB由于带宽大，可以很容易地实现远高于蓝牙的传输速度。超宽带的主要特点包括低成本、长电池寿命、多径抗扰度以及通信和同步精确测距能力。超宽带与现有无线电系统的频带重叠，可以更有效地利用稀缺的频谱资源。预期的应用包括智能家居和个性化服务、消费电子、家庭通信/儿童监督、工业和建筑自动化、跟踪和物流、资产标签和管理、搜索和救援、安全、医疗应用和军事应用等。

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.
