This award includes synergistic research in fundamental communications theory and the development of novel communications technologies. To make these research activities possible the principal investigators (PIs) will establish new and enhance the existing research infrastructure for research programs associated with the Center for Information Technology Research in the Interest of Society (CITRIS) and two of its members: the Berkeley Wireless Research Center (BWRC) and the Wireless Foundations Center (WFC). The purpose of this new infrastructure is to build a research environment that enables investigation of novel technologies for cognitive radios, high data rate transmission over wireless local area networks (WLANs), and wireless sensor networks. The wireless explosion that the researchers are witnessing today can be largely attributed to the availability of unlicensed spectrum bands. New unlicensed bands are being allocated, for example the 5GHz of spectrum available worldwide at 60GHz. At the same time, a large majority of available spectrum is locked in by its pre-allocated use in legacy systems. The PIs will investigate methods of overlaying the legacy systems with new wireless systems, which allow the use of ultra-wideband (UWB) radios to operate in the 3-10GHz band. Simultaneously, the FCC is considering allowing unlicensed 'cognitive' radios to overlay allocated bands, such as TV spectrum overlay.This award takes a broad and thorough inter-disciplinary approach to developing the fundamental understanding of the operation in new bands, such as 60GHz and UWB, spectrum reuse and spectrum recycling by cognitive radios, together with reducing the requirements of these systems to the basic hardware specifications of the underlying technology.The researchers are developing a common computational, test and measurement infrastructure that will allow a quantum leap in wireless technology research and its applications. By building a common computational infrastructure, consisting of compute servers, clusters of workstations and FPGA-based emulation, the researchers will foster the propagation of information from theory to prototypes. To fundamentally understand the physical properties of new bands as well as new methods of spectrum utilization and coexistence of various systems, the researchers will make a major investment in test and measurement infrastructure.Broader Impact. This common infrastructure will support the research of over a hundred graduate students, tens of undergraduate researchers and more than ten faculty. To maximize the impact, in addition to the traditional means of publications, the research results will be disseminated through participation in communications standardization processes, participation in government and NSF-sponsored studies on wireless technology and policies, and industry involvement. Research results will be used to form new graduate and undergraduate courses that will be taught in Berkeley and elsewhere.

该奖项包括基础通信理论的协同研究和新型通信技术的开发。 为了使这些研究活动成为可能，主要研究人员（PI）将建立新的和加强现有的研究基础设施，用于与社会利益信息技术研究中心（CITRIS）及其两个成员：伯克利无线研究中心（BWRC）和无线基金会中心（WFC）相关的研究项目。这个新的基础设施的目的是建立一个研究环境，使调查的新技术的认知无线电，高数据速率传输通过无线局域网（WLAN），和无线传感器网络。 研究人员今天目睹的无线爆炸在很大程度上可以归因于未授权频段的可用性。 正在分配新的未经许可的频带，例如在60 GHz处全球可用的5GHz频谱。 与此同时，大部分可用频谱被其在遗留系统中的预分配使用所锁定。 PI将研究用新的无线系统覆盖传统系统的方法，这些系统允许使用超宽带（UWB）无线电在3- 10 GHz频段内工作。 与此同时，FCC正在考虑允许未经许可的“认知”无线电覆盖分配的频段，如电视频谱覆盖。该奖项采取了广泛而彻底的跨学科方法，以发展对新频段（如60 GHz和UWB）的基本理解，认知无线电的频谱重用和频谱回收，同时将这些系统的要求降低到底层技术的基本硬件规格。研究人员正在开发一种通用的计算，测试和测量基础设施，这将使无线技术研究及其应用实现飞跃。 通过建立一个共同的计算基础设施，包括计算服务器，工作站集群和基于FPGA的仿真，研究人员将促进信息从理论到原型的传播。 为了从根本上了解新频段的物理特性以及频谱利用和各种系统共存的新方法，研究人员将在测试和测量基础设施方面进行重大投资。这个共同的基础设施将支持超过一百名研究生，数十名本科生研究人员和十多名教师的研究。 为了最大限度地扩大影响，除了出版物的传统方式外，还将通过参与通信标准化进程、参与政府和国家科学基金会赞助的关于无线技术和政策的研究以及行业参与来传播研究成果。 研究成果将用于形成新的研究生和本科生课程，将在伯克利和其他地方教授。
