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.

该奖项旨在开发和社区发布宽带软件可扩展无线电（WiSER）平台，沿着的是用于多节点动态频谱网络小型户外部署的参考实现。动态频谱技术对于无线社区具有战略重要性，因为迫切需要缓解由于移动的数据使用的持续指数增长而导致的频谱拥塞。虽然大量的理论工作已经做了动态频谱技术，明确的潜在收益的实验评估尚未进行。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操作的第一代技术，并且由于固有的处理限制，只能处理有限数量的MAC/PHY定制。拟议的WiSER平台是第二代宽带开源SDR平台，将在动态频谱和认知无线电网络领域进行新的实验研究。WiSER无线电？的目标发布时间与NSF、FCC、PCAST、NIST、DARPA和其他机构在动态频谱方面的重大新的国家研究和政策倡议相吻合。由于其关键技术特征，该平台能够进行比目前更丰富的实验动态频谱研究：以125 MHz的增量在400 MHz-4000 MHz之间运行，以100 Mbps或更高的速度对真实世界的PHY波形进行硬件加速，能够在同一平台上支持多个无线电的硬件虚拟化，以及开源软件工具包。该项目将开发一个社区资源，由目前可用的无线电沿着一个开放源码软件框架和参考系统实施。 这样的资源将允许研究一个非常稀缺和重要的公共资源？无线电频谱 通过改善对频谱的可靠访问，我们的社会在增强移动的宽带、改善公共安全通信以及确保雷达和其他频谱使用不会随着频谱使用密度的增加而降低方面受益。WiSER团队将与全国的实验研究小组密切合作，帮助开发动态频谱技术的相关和及时的实验部署。 动态频谱接入技术具有在频谱效率方面的数量级改进的潜力，这对于科普最近移动的数据业务的爆炸是必要的。认知无线电系统还将为最终用户提供更好的连接，并实现紧急响应系统和汽车网络等新应用。该项目将直接告知这些重要的社会需求，使研究界能够建立最先进的实验系统，对这些新兴技术进行结论性评估。 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。
