This award is aimed at the development and community release of a Wideband Software Extensible Radio (WiSER) platform along with a reference implementation for small outdoor deployment of a multi-node dynamic spectrum network. Dynamic spectrum technologies are strategically important to the wireless community because of the urgent need to alleviate spectrum congestion resulting from ongoing exponential growth in mobile data usage. While a great deal of theoretical work has already been done on dynamic spectrum techniques, definitive experimental evaluations of potential gains have yet to be conducted. The lack of experimental research is mainly due to the fact that available open platforms suitable for academic experimentation with software defined radio (SDR) are limited to first-generation technologies that operate at low bandwidth and can only handle a limited amount of MAC/PHY customization due to inherent processing constraints. The proposed WiSER platform is a second generation wideband open-source SDR platform that will enable new experimental research in the fields of dynamic spectrum and cognitive radio networking. The WiSER radio?s target release is timed to coincide with significant new national research and policy initiatives in dynamic spectrum involving the NSF, FCC, PCAST, NIST, DARPA and other agencies. This platform enables a richer range of experimental dynamic spectrum research than is currently possible because of its key technical features: operation across 400MHz-4000MHz in 125MHz increments, hardware acceleration for real-world PHY waveforms at speeds of 100 Mbps and higher, hardware virtualization capable of supporting multiple radios on the same platform, and an open-source software toolkit. This project will develop a community resource supported by currently available radios along with an open-source software framework and reference system implementation. Such a resource will allow for research into a very scarce and important public resource ? radio spectrum. By improving reliable access to spectrum, our society benefits in terms of enhancing mobile broadband, improving public safety communications, and ensuring that radar and other spectrum uses are not degraded as the spectrum becomes more densely used. The WiSER team will work closely with experimental research groups nationally to help develop relevant and timely experimental deployments of dynamic spectrum technology. Dynamic spectrum access technology has the potential for order-of-magnitude improvement in spectrum efficiency necessary to cope with the recent explosion of mobile data traffic. Cognitive radio systems will also provide improved connectivity to end users, and enable new applications such as emergency response systems and automotive networks. This project will directly inform these important societal needs by enabling the research community to build state-of-the-art experimental systems for conclusive evaluation of these emerging technologies. Lastly, this platform will offer a powerful educational tool for students wanting to better understand modern digital and software-based radio communications.

该奖项旨在奖励宽带软件可扩展无线电 (WiSER) 平台的开发和社区发布，以及多节点动态频谱网络小型室外部署的参考实现。动态频谱技术对于无线社区具有重要的战略意义，因为迫切需要缓解移动数据使用量持续呈指数增长所导致的频谱拥塞。虽然关于动态频谱技术已经做了大量的理论工作，但尚未对潜在收益进行明确的实验评估。实验研究的缺乏主要是由于适用于软件定义无线电（SDR）学术实验的可用开放平台仅限于在低带宽下运行的第一代技术，并且只能处理有限数量的 MAC/PHY 定制由于固有的加工限制。拟议的 WiSER 平台是第二代宽带开源 SDR 平台，它将支持动态频谱和认知无线电网络领域的新实验研究。 WiSER 无线电的目标发布时间恰逢涉及 NSF、FCC、PCAST​​、NIST、DARPA 和其他机构的动态频谱方面的重大新国家研究和政策举措。由于其关键技术特性，该平台能够实现比目前更丰富的实验动态频谱研究：以 125MHz 增量在 400MHz-4000MHz 范围内运行、以 100 Mbps 及更高速度对现实世界 PHY 波形进行硬件加速、支持硬件虚拟化支持同一平台上的多个无线电以及开源软件工具包。该项目将开发由当前可用无线电支持的社区资源以及开源软件框架和参考系统实现。 这样的资源将允许对非常稀缺且重要的公共资源进行研究？无线电频谱。 通过改善频谱的可靠接入，我们的社会将受益于增强移动宽带、改善公共安全通信以及确保雷达和其他频谱的使用不会随着频谱使用的更加密集而降低。 WiSER 团队将与全国实验研究小组密切合作，帮助开发相关且及时的动态频谱技术实验部署。 动态频谱接入技术有可能将频谱效率提高一个数量级，以应对近期移动数据流量的爆炸式增长。认知无线电系统还将为最终用户提供改进的连接性，并支持紧急响应系统和汽车网络等新应用。该项目将使研究界能够建立最先进的实验系统来对这些新兴技术进行结论性评估，从而直接满足这些重要的社会需求。 最后，该平台将为希望更好地了解现代数字和基于软件的无线电通信的学生提供强大的教育工具。
