在这份报告中，使用电视白色空间（TVWS）作为一个有前途的媒体，农村宽带接入的审查。所描述的技术评估试验是在新罕布什尔州的达勒姆及其周边地区进行的。七个客户端和两个基站被用来分析TVWS设备在郊区/农村环境中的性能。数据传输速率被认为是在宽带范围内的距离高达12.5公里，近的视线链接，但地形视线障碍造成的损失被认为有负面影响的性能。此外，一些传播模型进行检查，用于预测性能，以简化安装。功率谱测量是为了探索信号在UHF频率上的传播，并辨别它们如何与基于互联网的宽带速度测试测量的吞吐量速度相关。一些结论，该系统的性能，以及一些领域，需要更多的工作，以充分评估该系统。
In this report, the use of Television White Spaces (TVWS) as a promising medium for rural broadband access is examined. The technology assessment trial described is conducted in and around Durham, New Hampshire. Seven clients and two base stations are used to analyze the performance of the TVWS equipment in a suburban/rural environment. Data transmission rates were found to be in the broadband range over distances up to 12.5 km with near line-of-sight links, but losses caused by terrain line-of-sight obstructions were found to have a negative effect on performance. Additionally, some propagation models are examined for their use in predicting performance to simplify installations. Power spectrum measurements were made to explore the propagation of the signals over UHF frequencies and to discern how they correlate to throughput speeds measured by Internet-based broadband speed tests. Some conclusions are presented as to the performance of the system, as well as some areas where more work is needed to fully assess the system.
