Millimeter-wave is a core technology for next-generation wireless and cellular networks (5G and beyond). Networks using millimeter-wave technologies are expected to satiate the rapidly growing customer appetite for mobile data and to meet the stringent throughput, latency, and reliability requirements of emerging applications, such as immersive virtual and mixed reality, tactile internet, vehicular communications, and autonomous vehicles safety. However, high directionality, high channel dynamics, and sensitivity to blockages render state-of-the-art millimeter-wave technologies unsuitable for low-latency, high performance, and ultra-reliable applications. This research project focuses on designing software-hardware reconfigurable systems to address the key challenges and improve the performance, availability, and reliability of mobile millimeter-wave networks. This project will impact the broader population positively because it yields near-term benefits in 5G infrastructure and paves the way for long-term millimeter-wave research. Furthermore, this project will engage in outreach activities and involve a diverse set of students, particularly, women and minorities, leveraging the experimental nature of the research on next-generation wireless and cellular networks.The project addresses the key challenges by executing three thrusts: (1) MilliNet: To overcome high signal attenuation, millimeter-wave radios must focus their power via highly directional, electronically steerable beams. But, aligning the beams and maintaining the link between devices during obstruction and mobility are the fundamental barriers toward reliable connection. MilliNet, a faster beam alignment protocol, draws on ideas from the sparse channel recovery, allowing the radios to quickly discern the best physical millimeter-wave paths even under thousands of beams and picocell choices. (2) ReconMilli: To achieve spectrum flexibility, next-generation radios must be able to operate over a wide range of the spectrum, from micro-wave to millimeter-wave. But the fundamental challenge is that physical space on mobile devices is limited. ReconMilli, a reconfigurable antenna design, joins multiple millimeter-wave antennas physically into a micro-wave antenna, but splits it, when needed, into multiple millimeter-wave antennas; thus, achieving spectrum flexibility and saving physical space. (3) LiMesh: To make the deployment and maintenance of a 5G picocell mesh easy, mobile operators will use multi-Gbps fixed millimeter-wave links. Yet, disruptions in the wireless mesh are common; but, more importantly, such disruptions are catastrophic for ultra-reliable connectivity. LiMesh, an ultra-reliable picocell mesh design, leverages the fixed geometrical arrangement of the directional links to infer disruptions using a space-time failure correlation metric proactively. The research project will design, build, and empirically validate the proposed systems in millimeter-wave wireless test-beds.This project is jointly funded by the Computer and Network Systems (CNS) division and the Established Program to Stimulate Competitive Research (EPSCoR).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.

毫米波是下一代无线和蜂窝网络（5G及以后）的核心技术。使用毫米波技术的网络有望满足客户对移动的数据快速增长的需求，并满足新兴应用（如沉浸式虚拟和混合现实、触觉互联网、车载通信和自动驾驶汽车安全）对吞吐量、延迟和可靠性的严格要求。然而，高方向性、高信道动态性和对阻塞的敏感性使得最先进的毫米波技术不适合低延迟、高性能和超可靠的应用。该研究项目的重点是设计软件-硬件可重构系统，以解决关键挑战，提高移动的毫米波网络的性能，可用性和可靠性。该项目将对更广泛的人群产生积极影响，因为它在5G基础设施方面产生了短期效益，并为长期毫米波研究铺平了道路。此外，该项目还将开展外联活动，吸引各种学生，特别是妇女和少数民族学生参与，利用下一代无线和蜂窝网络研究的实验性质，该项目通过执行三个重点来应对关键挑战：（1）MilliNet：为了克服高信号衰减，毫米波无线电必须通过高度定向的电子可控波束集中其功率。但是，在障碍和移动期间对齐光束并保持设备之间的链接是实现可靠连接的基本障碍。MilliNet是一种更快的波束对准协议，它借鉴了稀疏信道恢复的想法，即使在数千个波束和微微蜂窝选择的情况下，无线电也能快速识别最佳物理毫米波路径。(2)ReconMilli：为了实现频谱灵活性，下一代无线电必须能够在从微波到毫米波的广泛频谱范围内工作。但最根本的挑战是移动的设备上的物理空间是有限的。ReconMilli是一种可重新配置的天线设计，它将多个毫米波天线物理连接到一个微波天线中，但在需要时将其拆分为多个毫米波天线;从而实现频谱灵活性并节省物理空间。(3)LiMesh：为了简化5G微微蜂窝网的部署和维护，移动的运营商将使用多Gbps固定毫米波链路。然而，无线网格中的中断是常见的;但更重要的是，这种中断对于超可靠的连接来说是灾难性的。LiMesh是一种超可靠的微微蜂窝网格设计，它利用定向链路的固定几何布置，主动使用时空故障相关度量来推断中断。该研究项目将在毫米波无线测试台上设计、建造和经验验证拟议的系统。该项目由计算机和网络系统（CNS）部门和刺激竞争研究的既定计划（EPSCoR）共同资助。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。
