项目摘要

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.

该项目的主要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。该项目将实现从塔到四个聚合客户端的首次 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，覆盖范围从 500 MHz 到 100 GHz。该塔位于德克萨斯州休斯顿的经济贫困地区，将为当地社区服务。通过“Technology For All”，该项目团队拥有与当地社区互动的历史，涵盖从宽带接入到技术培训的各个方面。该项目的成果将为美国和全球其他社区提供一个模板。该项目的目标是通过展示新兴和多样化频段的新颖使用案例，为频谱政策和 FCC 提供信息和影响。该项目将通过展示新的多样化频段的可行性来影响未来的标准。该项目将通过成果展示以及团队广泛的协作行业网络对行业产生影响。最后，该项目包括跨学科教育计划，团队包括多名博士。该项目的目标是从根本上推进当今千兆位/秒规模的系统，并实现用于固定回程和移动接入的太比特每秒无线网络。突破 Tb/秒的障碍需要将速率提高 100 倍，甚至超出大规模 MIMO 和全双工等 5G 进步所实现的预期收益。为了实现这一愿景，项目团队提出了以下综合研究重点。第一个项目主旨是开发和制造 10,000 个元件的 100 GHz 发射和接收阵列。关键技术是模块化数字脉冲片上辐射设计，可提供前所未有的方向性。其次，该项目的目标是通过以下方式实现 Tb/秒对移动客户端的聚合访问：(1) 利用跨越两个数量级的频谱特性进行高方向性发送器-接收器波束对准，以及 (2) 逐步聚合极化客户端以实现同时传输多个客户端，同时控制流间干扰。最终的项目重点实现了在 20 米高的城市塔以及多个客户端站点上部署所有系统组件。一个关键成果将是在操作和受控测试场景中对吞吐量及其基本决定因素进行广泛的测量活动。
