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

该项目的发展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个TB/秒传输，每个客户端的传输速率为300 GB/秒和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，跨度从500 MHz到100 GHz。这座塔位于德克萨斯州休斯敦的一个经济困难地区，将为当地社区服务。通过全民技术，该项目团队拥有与当地社区接触的历史，范围从宽带接入到技术培训。项目成果将为美国和全球其他社区提供模板。该项目旨在通过演示新兴和多样化的频谱频段的新使用案例来告知和影响频谱政策和联邦通信委员会。该项目将通过展示在新的和多样化的频段中什么是可行的来影响未来的标准。该项目将通过展示结果以及团队广泛的协作行业网络来影响行业。最后，该项目包括一个跨学科的教育计划，该团队包括来自代表性不足群体的多名博士生。该项目的目标是从根本上推进今天的千兆位/秒规模的系统，并实现固定回程和移动接入的每秒太比特的无线网络。突破TB/秒的障碍需要将速率提高100倍，甚至超过通过大规模MIMO和全双工等5G进步实现的预期收益。为了实现这一愿景，项目组提出了以下综合研究推动力。第一个项目的推力是开发和制造100 GHz的10,000个单元发射和接收阵列。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方向性。其次，该项目的目标是通过(1)利用跨越两个数量级的频谱的特性来实现高方向性发送器-接收器波束对准，以及(2)递增地聚合极化客户端以实现对多个客户端的同时传输，同时控制流间干扰，从而实现对移动客户端的TB/秒聚合接入。最终的项目推力实现了在一座20米长的城市塔楼上部署所有系统组件以及多个客户站点。一个关键的结果将是在操作和受控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.
