NeTS - WN - Spectrum Observatory System

这个研究项目在芝加哥建立了一个永久性的光谱观测站，以监测和支持为期三年的频谱使用分析。这个天文台由一个移动频谱占用平台补充，以游牧方式检查各个目标城市，以探索“未使用的频谱”，并在芝加哥验证固定的天文台读数作为该城市的代表性测量。选择郊区和农村进行测量，以扩大对这些环境中频谱使用差异的理解。研究的重点是：1)获取占用数据；2)分析数据中的异常和趋势；3)通过观察到的使用模式来研究提高频谱利用率的机会。该基金支持学术界、工业界和政府机构之间的合作研究。研究影响：1)收发器设计者，2)认知无线电研究人员，3)频谱所有者和利益相关者，4)工程学生和教师，5)监管机构。这些信息的最大影响可能是美国政府的通讯政策。目前，频谱占用信息充其量是零星的，导致最坏情况分析，政策保守，频谱资源利用率低。新兴的电信技术需要大大提高对频谱利用和趋势的了解才能发挥作用。该频谱观测站是频谱预测的基础，对认知无线电系统、新型无线设备和网络的成功大规模部署至关重要。最后，本研究为无线通信网络的研究生和本科生课程提供了一个非常有用的学术平台。

This research project establishes a permanent Spectrum Observatory in Chicago to monitor and support the analysis of spectrum usage for a three-year period. This observatory is supplemented by a mobile spectrum occupancy platform to nomadically examine various target cities to both explore "unused spectrum" and in Chicago to validate the fixed observatory readings as representative measurements for the city. Selected suburban and rural measurements are performed to expand the understanding of the differences in spectrum usage in these environments. The research focuses on: 1) obtaining the occupancy data, 2) analyzing the anomalies and trends in the data, and 3) examining the opportunities for improved spectral utilization suggested by the observed usage patterns. This grant supports collaborative research across and between academia, industry, and government entities. The research impacts: 1) transceiver designers, 2) cognitive radio researchers, 3) spectrum owners and stakeholders, 4) engineering students and faculty, and 5) regulators. The greatest impact of this information may be to U.S. government communications policy. Currently, information on spectrum occupancy is spotty at best, leading to worst-case analysis, conservative policies, and poor utilization of the scare spectrum resource. Emerging telecommunication technologies require a vastly improved understanding of spectrum utilization and trends to be effective. This Spectrum Observatory serves as the basis for spectrum forecasting that is crucial for the successful broad scale deployment of cognitive radio systems, new wireless devices, and networks. Finally, this study provides a very useful academic platform for graduate and undergraduate courses in wireless communication networks.
