UC Berkeley Wireless Research Infrastructure Program

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）将为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）和无线基础中心（WFC）相关的研究项目建立新的和增强现有的研究基础设施。这个新基础设施的目的是建立一个研究环境，使研究认知无线电、无线局域网（wlan）上的高数据速率传输和无线传感器网络的新技术成为可能。研究人员今天所见证的无线爆炸，在很大程度上可以归因于未经许可的频谱带的可用性。新的未经许可的频段正在被分配，例如60GHz的5GHz全球可用频谱。与此同时，大部分可用频谱由于在遗留系统中预先分配的用途而被锁定。pi将研究用新的无线系统覆盖传统系统的方法，该系统允许使用超宽带（UWB）无线电在3-10GHz频段工作。与此同时，美国联邦通信委员会正在考虑允许未经许可的“认知”无线电覆盖已分配的频段，例如电视频谱覆盖。该奖项采用广泛而彻底的跨学科方法，以发展对新频段（如60GHz和UWB）操作的基本理解，通过认知无线电进行频谱重用和频谱回收，同时降低这些系统对底层技术的基本硬件规格的要求。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巨大飞跃。通过建立一个通用的计算基础设施，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的新方法和各种系统的共存，研究人员将在测试和测量基础设施方面进行重大投资。更广泛的影响。这个共同的基础设施将支持一百多名研究生，数十名本科生研究人员和十多名教师的研究。为了最大限度地发挥影响，除了传统的出版手段外，研究成果还将通过参与通信标准化进程、参与政府和nsf赞助的无线技术和政策研究以及行业参与来传播。研究成果将用于形成新的研究生和本科课程，这些课程将在伯克利和其他地方教授。

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.
