EARS: Terabit-per-second Scale Networking: Design to Field Trials, Lab to Tower

该项目的驱动愿景是通过基础研究、原型设计和概念验证现场试验来打破太比特/秒的网络障碍。该项目将实现从一个塔到四个聚合客户端的第一次Tb/秒传输，每个客户端的传输速度为300 Gb/秒，传输距离为300米。该项目将同时实现有史以来部署的最多样化的频谱接入塔，范围从500 MHz到100 GHz。该塔位于德克萨斯州休斯顿的一个经济落后地区，将为当地社区服务。通过“人人享有技术”，项目团队在从宽带接入到技术培训等各个领域与当地社区进行接触方面有着悠久的历史。该项目的成果将为美国和全球其他社区提供一个模板。该项目旨在通过展示新兴和多样化频谱带的新使用案例，为频谱政策和FCC提供信息和影响。该项目将通过展示在新的和不同的频段中什么是可行的来影响未来的标准。该项目将通过结果演示以及团队广泛的协作行业网络对行业产生影响。最后，该项目包括一个跨学科的教育计划，团队包括来自弱势群体的多名博士生。该项目的目标是从根本上推进当前Gb/s规模的系统，并实现用于固定回程和移动接入的每秒太比特无线网络。突破Tb/秒的障碍需要将速率提高100倍，甚至超过大规模MIMO和全双工等5G技术所实现的预期收益。为了实现这一愿景，项目团队提出了以下综合研究重点。第一个项目的重点是开发和制造一个100千兆赫的10000元发射和接收阵列。关键技术是一种模块化的数字脉冲芯片辐射设计，它提供了前所未有的指向性。其次，该项目的目标是通过(1)利用两个数量级以上的频谱跨越特性实现高指向性发送方-接收方波束对准；(2)增量聚合极化客户端，在控制流间干扰的同时，实现向多个客户端同时传输。最终的项目推力实现了在20米高的城市塔楼以及多个客户站点上部署所有系统组件。一个关键的结果将是在操作和控制测试场景中对吞吐量及其潜在决定因素进行广泛的测量活动。

The driving vision of this project is to break the Terabit/sec networking barrier through fundamental research, prototype designs, and proof-of-concept field trials. This project will realize the first Tb/sec transmission from a tower to four aggregated clients, each at 300 Gb/sec and 300 meters. The project will simultaneously realize the most diverse spectrum access tower ever deployed, spanning from 500 MHz to 100 GHz. The tower is located in an economically disadvantaged area of Houston, Texas, and will serve the local community. Through Technology For All, the project team has a history of engaging the local community spanning from broadband access to technology training. The project outcomes will provide a template for other communities in the US and globally. This project targets to inform and impact spectrum policy and the FCC via demonstration of novel usage cases of emerging and diverse spectral bands. This project will impact future standards by demonstrating what is feasible in new and diverse bands. This project will impact industry through demonstration of results coupled with the team's extensive collaborative industry network. Finally, the project includes an inter-disciplinary education plan and the team includes multiple Ph.D. students from under-represented groups.The project's objective is to fundamentally advance today's Gb/sec-scale systems and realize terabit-per-second wireless networks for both fixed backhaul and mobile access. Breaking the Tb/sec barrier requires a 100x increase in rate even beyond expected gains realized from 5G advances such as massive MIMO and full duplex. To realize this vision, the project team proposes the following integrated research thrusts. The first project thrust is development and fabrication of a 10,000 element transmit and receive array at 100 GHz. The key technique is a modular digital-to-impulse on chip radiating design that provides unprecedented directivity. Second, the project targets Tb/sec aggregate access to mobile clients by (1) exploiting the properties of spectrum spanning over two orders of magnitude for high-directivity sender-receiver beam alignment and (2) incrementally aggregating polarized clients to enable simultaneous transmission to multiple clients while controlling inter-stream interference. The final project thrust realizes deployment of all system components on a 20 meter urban tower along with multiple client sites. A key outcome will be an extensive measurement campaign of throughput and its underlying determinants in both operational and controlled testing scenarios.
