Internet-of-things (IoT) is becoming a reality as our surroundings are getting evermore connected. The International Telecommunication Union is forecasting 100 times increase in the aggregate wireless demand by 2030 relative to 2020. The increasing density of IoT devices in civilian life imposes more stringent efficiency requirements on the use of radio frequencies, also called spectrum. The wireless community has made excellent spectrum efficiency innovations by solving interference challenges of omni-directional radios that propagate in every direction. However, it is questionable if these innovations alone will suffice as cost-effective and secure solutions for future wireless needs. As a promising solution, by transmitting in certain directions, directional radios offer high-speed wireless access, as well as wireless transmissions with lower energy consumption and probability of being intercepted by intruders. However, radio directionality has disadvantages in terms of tolerance to mobility and antenna size; and requires transmitter and receiver to be facing each other, a.k.a. line-of-sight (LOS) alignment, and larger antenna size. This project adapts Software-Defined Radio (SDR), i.e., radio components implemented in software that enable dynamic programmability, to handle the challenges in mobility and LOS alignment of directional transceivers, and to attain practical antenna sizes. The project takes the first steps in making directionality of transceivers a programmable element of SDR platforms. Broader impacts include technical contributions to the 5G-and-beyond vision, the radio infrastructure needed for future smart cities and connected communities, and further proliferation of wireless technology into civilian life. The project offers research opportunities to UCF undergraduate and graduate students, including under-represented minorities.The intellectual merit is making directionality a mainstream wireless design component. The project enhances directional antenna design and angular diversity packaging in the higher frequency spectrum bands, progresses the theory of interference and power management for highly directional links, and provides energy efficient and seamless LOS detection and maintenance of mobile directional links. In particular, the project explores Directional SDR designs that (1) introduce low-cost reflectarray antennas with beam-steering capability, (2) utilize low-power directional transceiver packages with angular diversity in circular or spherical shapes, (3) discover, establish, and maintain directional and/or LOS-requiring links under mobility, (4) perform software-defined beamforming by using highly directional links under mobility, and (5) employ fast heuristics to directionally sense the spectrum and optimize the directional communication link parameters on-the-fly. Focusing on the emerging high frequency bands at 60 GHz and above, the effort explores new methods and technologies for operation at short ranges representing an urban or indoor setting. The overarching goal is to investigate wireless link management and optimization regimes where directionality is the new norm and a mainstream design parameter.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.

随着周围环境的连接不断，THINeting（IoT）正在成为现实。国际电信联盟预测，到2030年相对于2020年，无线需求的总需求增加了100倍。平民生活中物联网设备的密度日益增加，对使用无线电频率的使用施加了更严格的效率要求，也称为Spectrum。无线社区通过解决了朝各个方向传播的全面收音机的干扰挑战，从而实现了出色的频谱效率创新。但是，仅凭这些创新就足以满足未来无线需求的解决方案，这是值得怀疑的。作为一种有希望的解决方案，通过向某些方向传输，定向无线电可提供高速无线访问，以及较低的能量消耗和被入侵者拦截的概率的无线传输。但是，无线电方向性在耐受性和天线大小方面存在缺点。并要求发射器和接收器彼此面对，也就是视线线（LOS）对准和较大的天线大小。该项目适应软件定义的无线电（SDR），即在软件中实现的无线电组件，以启用动态可编程性，以应对方向收发器的移动性和LOS对齐方面的挑战，并达到实用的天线尺寸。该项目采取了第一步，将收发器的方向性成为SDR平台的可编程元素。更广泛的影响包括对5G和Be-Beyond Vision的技术贡献，未来智慧城市和互联社区所需的无线电基础设施，以及将无线技术进一步扩散到平民生活中。该项目为UCF的本科生和研究生提供了研究机会，包括代表性不足的少数群体。智力优点使方向性成为主流的无线设计组成部分。该项目在更高频谱频段中增强了定向天线设计和角度多样性包装，以高度方向链路进行干扰和功率管理理论，并提供节能和无缝的LOS检测以及移动方向链路的维护。特别是，该项目探讨了（1）引入具有梁发光能力的低成本反射式天线，（2）利用低功率定向收发器包装，具有角度多样性的圆形或球形形状，（3）在圆形或球形的形状中，（3）通过在动机下进行高度链接，并在高度链接下，并建立并保持了方向的链接（4）链接（4）链接（4）链接（4）链接（4）链接（4）的链接（4）链接（4）链接（4）表现（4）链接（4） （5）采用快速的启发式方法来定向感知频谱并在线上优化定向通信链接参数。为了关注60 GHz及以上新兴的高频带，这项工作探索了代表城市或室内环境的短范围内运行的新方法和技术。总体目标是调查定向性是新规范和主流设计参数的无线链接管理和优化制度。该奖项反映了NSF的法定任务，并被认为是值得通过基金会的智力优点和更广泛影响的评估审查标准来通过评估来获得支持的。
