Phase II IUCRC University of Arizona: Broadband Wireless Access and Applications Center (BWAC)

该项目是宽带无线接入中心（BWAC）的第二阶段，BWAC是一个多大学多行业组织，由五所大学（亚利桑那大学、弗吉尼亚理工大学、圣母大学、密西西比大学和美国天主教大学）和来自行业和政府的20多个附属机构组成。在过去的十年中，无线通信取得了重大的技术飞跃。无线连接在社会中无处不在，导致无线频谱短缺、网络拥塞、网络攻击和个人安全问题。BWAC的使命是应对这些挑战并提供创造性的解决方案。在第二阶段，BWAC将扩大其研究范围，以应对无线网络中及时和行业相关的挑战。该中心的研究重点包括异构无线系统的频谱共享，安全和私有无线通信，多天线（MIMO）信号处理技术，毫米波（mmW）系统和协作移动的边缘计算（MEC）系统。UA站点在无线协议、频谱共享和物理层安全性方面拥有丰富的专业知识。所进行的项目将包括互操作频谱共享机制、波束成形、大规模MIMO、无窃听安全通信技术、毫米波系统天线设计以及机会频谱接入中全双工和自干扰消除的自适应方案。这个产学合作中心的成果将对公共福利产生直接影响，使远程医疗、智能交通、物联网和农村地区的高速宽带接入等应用成为可能。伙伴大学致力于扩大对BWAC活动的参与。这是通过REU网站程序，代表性不足的少数民族学生和教师参与研究项目，并参与多学科项目来实现的。凭借其研究，建立的伙伴关系以及成员之间的长期合作历史，BWAC可能会创建知识产权和分拆公司，从而导致就业增长。亚利桑那大学作为牵头网站，管理着BWAC中心项目网站www.bwac.arizona.edu。该网站包含中心概况、使命、行业成员、项目、会议公告和技术数据等各种信息。中心专有文件通过需要访问凭证的安全内部页面进行管理。 数据储存库将在主网站上管理，并与其他大学网站链接。储存库将包含技术文件、项目描述、相关软件、测试台细节等。储存库将在项目期间以及项目终止后的五年内进行维护。该奖项反映了NSF的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评估，被认为值得支持。

This project is Phase II of the Broadband Wireless Access Center (BWAC), a multi-university multi-industry organization composed of five universities (the University of Arizona, Virginia Tech, University of Notre Dame, University of Mississippi, and the Catholic University of America) and 20+ affiliates from industry and government. In the past decade, wireless communications has made major technological leaps. Wireless connectivity is pervasive in society, leading to a shortage in wireless spectrum, network congestion, cyber-attacks and personal security issues. The mission of BWAC is to address these challenges and offer creative solutions. In Phase II, BWAC will expand its research footprint to address timely and industry-relevant challenges in wireless networks. Research thrusts for the center include spectrum sharing for heterogeneous wireless systems, secure and private wireless communications, multi-antenna (MIMO) signal processing techniques, millimeter wave (mmW) systems, and collaborative mobile edge computing (MEC) systems. The UA site has significant expertise in wireless protocols, spectrum sharing, and physical-layer security. Projects conducted will include inter-operable spectrum sharing mechanisms, beamforming, massive MIMO, techniques for eavesdropping-free secure communications, antenna design for mmW systems, and adaptive schemes for full-duplex and self- interference cancellation in opportunistic spectrum access. The results of this collaborative industry-university center will have a direct effect on public well-fare, enabling applications such as remote health, smart transportation, internet of things, and high speed broadband access in rural areas, to name a few. The partnering universities are committed to broadening participation in BWAC's activities. This is achieved through REU site programs, participation of under-represented minority students and faculty in research projects, and involvement of multidisciplinary projects. With its research, established partnerships, and long history of collaboration between its members, BWAC will likely create intellectual property and spin-off companies, leading to job growth. The lead site, University of Arizona manages the central BWAC project website at www.bwac.arizona.edu. This website contains various information about the center including the overview of the center, mission, industry membership, projects, meeting announcements and technical data. Center proprietary documents are managed through a secure internal pages requiring access credentials. The data repository will be managed at the main website with links to the other university sites. The repository will contain technical papers, project descriptions, relevant software, testbed details, etc. The repository will be maintained during the project and for an additional five years beyond its termination.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.
