Fifth generation (5G) cellular and millimeter-wave (mm-wave) networks are expected to play a significant role in next generation communication and sensing systems. Indeed, mm-wave technology provides multi-Gigabit-per-second (Gbps) data rates to mobile and Internet-of-Things (IoT) devices, projected to grow to 200 billion by 2020. Currently, 5G/mm-wave research is very active. However, to effectively study, design, and characterize 5G/mm-wave systems, new state-of-the-art instrumentation is needed, traditionally not present in academic labs. The proposed instrumentation will provide unprecedented measurement and characterization capabilities of 5G/mm-wave antennas and devices. Therefore, it will enable Florida International University (FIU) to: (a) conduct current and future cutting-edge 5G/ mm-wave research projects, (b) develop novel 5G/mm-wave technologies for cellular networks, satellite and airborne communications, as well as brain studies and cancer diagnoses and treatments, (c) offer new opportunities to train post-docs, graduate, undergraduate, and K-12 students to become experts in high frequency radio frequency (RF) technologies, creating much needed national workforce in this area, (d) serve as a state-of-the-art technical hub in South Florida, attracting new statewide, national and international academic and industry collaborators, (e) foster new opportunities for cross-disciplinary and multi-institutional research, and (f) support the growth of a strong and diverse U.S. workforce in RF communication. Therefore, the proposed instrumentation will have significant impact in research, education, and technology development. This acquisition will further advance FIU's educational efforts to broaden participation of women and other underrepresented groups in STEM through curriculum development, REU programs, and outreach efforts. The proposed instrumentation from Microwave Vision Group (MVG), called -Lab, is highly specialized and incorporates important requirements for compatibility and interoperability, across 18 GHz to 110 GHz. This instrumentation consists of an anechoic chamber equipped with absorbers, precision positioning control system, RF equipment modules (network analyzers, coaxial cables, waveguides, probes, etc.) and data post-processing. Different modules are required for different frequency bands viz. K (18-26 GHz), Ka (26-40 GHz), V (50-75GHz), and W (75-110GHz) bands. Research in the frequency range 18-110 GHz has so far been impeded by the lack of affordable testing equipment with large measurement inaccuracies. This is mostly due to the small footprint of related RF devices. As a result, research activities in related communications, biomedical, and other scientific fields have been so far limited to much lower frequency range. The procurement of such instrumentation will eschew traditional limitations often encountered with high frequency testing and characterization of future mm-wave, terahertz, and IoT components devices and systems. The broadband frequency (18-110GHz) offered by this instrumentation will enable groundbreaking and transformative research in RF communications with multi-Gbps data rates. Such capability will revolutionize a) cellular networks, b) airborne and satellite communication systems, c) vehicle-to-vehicle communications, d) reconfigurable and deployable RF systems, e) wearable and implantable devices, f) brain and cancer studies, g) terahertz and mm-wave cameras, h) terahertz sources and on-chip terahertz antennas, and i) secure communications among others. In summary, research in 5G and mm-wave technologies, which will be enabled by the proposed instrumentation, is expected to have great impact on information technology, telecommunications, diagnosis of diseases and biomonitoring, thereby improving quality of life and health.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.

第五代（5G）蜂窝和毫米波（mm波）网络预计将在下一代通信和传感系统中发挥重要作用。事实上，毫米波技术为移动的和物联网（IoT）设备提供了每秒数千兆位（Gbps）的数据速率，预计到2020年将增长到2000亿。目前，5G/mm波的研究非常活跃。然而，为了有效地研究、设计和表征5G/毫米波系统，需要新的最先进的仪器，而传统上学术实验室中没有这种仪器。拟议的仪器将为5G/毫米波天线和设备提供前所未有的测量和表征能力。因此，它将使佛罗里达国际大学（FIU）：（a）开展当前和未来的尖端5G/毫米波研究项目，（B）为蜂窝网络、卫星和机载通信以及大脑研究和癌症诊断和治疗开发新型5G/毫米波技术，（c）为培养博士后、研究生、本科生、和K-12学生成为高频射频（RF）技术的专家，在这一领域创造急需的国家劳动力，（d）作为南佛罗里达最先进的技术中心，吸引新的全州，国家和国际学术和工业合作者，（e）为跨学科和多机构研究提供新的机会，（f）支持美国在射频通信领域强大而多样化的劳动力队伍的发展。因此，所提出的仪器将在研究，教育和技术开发方面产生重大影响。这一收购将进一步推进金融情报室的教育工作，以扩大妇女和其他代表性不足的群体在干通过课程开发，REU方案和外联工作的参与。Microwave Vision Group（MVG）提出的仪器称为-Lab，是高度专业化的，并在18 GHz至110 GHz范围内集成了兼容性和互操作性的重要要求。该仪器包括一个装有吸收器的电波暗室、精密定位控制系统、射频设备模块（网络分析仪、同轴电缆、波导、探头等）。和数据后处理。 不同的模块需要用于不同的频带，即K（18-26 GHz）、Ka（26-40 GHz）、V（50- 75 GHz）和W（75- 110 GHz）频带。到目前为止，由于缺乏负担得起的测量误差很大的测试设备，18-110 GHz频率范围内的研究一直受到阻碍。这主要是由于相关RF器件的占用空间小。因此，相关通信、生物医学和其他科学领域的研究活动迄今为止一直局限于低得多的频率范围。这种仪器的采购将避免未来毫米波、太赫兹和物联网组件设备和系统的高频测试和表征经常遇到的传统限制。该仪器提供的宽带频率（18- 110 GHz）将使具有多Gbps数据速率的RF通信的突破性和变革性研究成为可能。 这种能力将彻底改变a）蜂窝网络，B）机载和卫星通信系统，c）车辆到车辆通信，d）可重新配置和可部署的RF系统，e）可穿戴和可植入设备，f）大脑和癌症研究，g）太赫兹和毫米波相机，h）太赫兹源和片上太赫兹天线，以及i）安全通信等。 综上所述，利用该仪器进行的5G和毫米波技术研究，有望对信息技术、电信、疾病诊断和生物监测产生重大影响，从而提高生活质量和健康水平。该奖项反映了NSF的法定使命，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。
