This award is funded in whole or in part under the American Rescue Plan Act of 2021 (Public Law 117-2).Visible Light Communication (VLC) is an emerging technology that uses light (optical) energy to communicate. VLC is increasing in popularity for research and development, however, still has significant gaps to cover to become a standalone mobile technology. These gaps are particularly in improving communication data rates and range, making the technology viable for mobile conditions, and conditioning the technology for low-energy battery sourced operation. Today, the development efforts in VLC have largely been confined within a limited set of research labs around the globe, thus making the technology less accessible and known to the public. This also puts students and faculty from academic departments which do not have the infrastructure and knowledge--base to teach and/or research in VLC at a great disadvantage. With an overarching vision to realize VLC as a practical wireless commercial mobile technology, this project executes a plan to achieve this goal through a unified set of integrated research, education, and outreach activities. This project studies and designs machine learning models to improve throughput, design novel techniques for maintaining VLC links under mobility, designs energy-aware strategies for VLC transmission and reception, and experimentally validates the solutions through prototype implementations under controlled and real-world conditions. In parallel, this project performs educational outreach that is well-integrated with the research efforts, by developing research experiences for undergraduates (REU) and designing a novel VLC hands-on learning kit to be made freely accessible to the public.This project’s five-year research and education plan focuses on addressing the fundamental impediments for realizing reliable and robust VLC under practical constraints in real world applications. The target goals for VLC performance are medium-long ranges, Mega-Giga bits-per-second throughput and battery operation under static and mobile conditions. To achieve these goals, this project uses an experimentation and data driven approach realized through a set of integrated research and educational activities along five key objectives, which are: 1.) Achieving High Throughput and Long Range using novel transmission and reception techniques; 2.) Building Mobility Resilience using novel hardware and sensor-fusion; 3.) Optimizing Energy Usage using novel signal designs and low-energy communication protocols; 4.) Prototype Implementation and Experimental Evaluation; and 5.) Enhance VLC Education and Outreach. The VLC learning kit creates a new resource for the VLC research community and the public. The REU efforts create a direct impact on URM students in Atlanta and Georgia State University’s large population of African-American and Hispanic students. Overall, this project motivates the community to study and operate VLC in real-world conditions.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.

该奖项的全部或部分资金根据《2021 年美国救援计划法案》（公法 117-2）提供。可见光通信 (VLC) 是一种使用光（光）能进行通信的新兴技术，越来越受欢迎。然而，在研究和开发方面，要成为一种独立的移动技术，仍然有很大的差距需要弥补，这些差距特别是在提高通信数据速率和范围、使该技术适用于移动条件以及调节该技术以适应低能量电池来源方面。如今，VLC 的开发工作主要局限于全球范围内有限的研究实验室，从而使得该技术不太容易为公众所了解和了解，这也使得那些不具备该技术的学术部门的学生和教职员工也难以了解该技术。 VLC 教学和/或研究的基础设施和知识库处于极大劣势。该项目的总体愿景是将 VLC 实现为实用的无线商业移动技术，因此执行了一项计划，通过一套统一的综合研究来实现这一目标。 、教育和外展活动。设计机器学习模型以提高吞吐量，设计用于在移动性下维持 VLC 链路的新技术，设计 VLC 传输和接收的能源感知策略，并通过在受控和现实条件下的原型实施来实验验证解决方案。通过为本科生 (REU) 开发研究经验并设计可供公众免费使用的新型 VLC 实践学习套件，开展与研究工作完美结合的教育推广。该项目的五年研究和教育计划重点关注解决在现实应用的实际限制下实现可靠​​和鲁棒的 VLC 的根本障碍是中长距离、每秒兆比特的吞吐量以及静态和移动条件下的电池运行。为了实现这一目标，该项目采用了实验和数据驱动的方法，通过一系列综合研究和教育活动实现了五个关键目标，这些目标是： 1.) 使用新颖的传输和接收技术实现高吞吐量和远距离 2.) 构建移动性；使用新颖的硬件和传感器融合实现弹性；3.) 使用新颖的信号设计和低能耗通信协议优化能源使用；4.) 原型实施和实验评估；以及 5.) 增强 VLC 学习套件的创建。 REU 的努力对亚特兰大 URM 学生和佐治亚州立大学的大量非裔美国人和西班牙裔学生产生了直接影响。在现实条件下研究和操作 VLC。该奖项反映了 NSF 的法定使命，并通过使用基金会的智力价值和更广泛的影响审查标准进行评估，被认为值得支持。
