项目摘要

Gigabit-per-second scale wireless transmission is already commercially available in wireless local area networks (WLANs). For example, the latest Wi-Fi standard at 60 gigahertz promises data rates up to 100 gigabits per second The objective of this project is to realize the next order of magnitude in data rate, spectrum access, directionality, and spatial multiplexing targeting terabit per second WLANs with a low-latency control plane that supports mobile clients. Namely, scaling spectrum access towards terahertz will provide a key ingredient to realize the sixth generation of wireless networks. Thus, this project will result in the design, implementation, and proof-of-concept demonstration of a WLAN architecture using spectrum from 100 gigahertz to 500 gigahertz with range exceeding 100 meters.This project targets to scale multi-stream data rates to terabit per second for mobile clients via the following integrated research thrusts. The first project thrust provides two underlying building blocks for steerable and highly directional beams from 100 GHz to 500 GHz: (1) A first-of-its-kind pixelated metasurface waveguide will be developed to dynamically steer a THz beam via electrical switching of the meta-elements. (2) A THz leaky waveguide's unique property of coupling frequency and steering angle will be exploited for the first time to provide frequency-selective adaptive beam steering. The second project thrust targets scaling to high-density user populations. First, new smart reflecting surfaces will be developed that will enable engineered non-specular non-line-of-sight paths. This thrust will experimentally study the achievable network density under different architectural components, identifying empirical limits at THz scale of packing many simultaneous physical links into a limited spatial area. The third project thrust targets to provide uninterrupted Tb/sec scale communication even in the presence of user and environmental mobility. The project's methodology aims to scale the control plane to a large and dense mobile WLAN via a novel spectral signature for each transmission and reception angle. Namely, with a terahertz rainbow emitted from a leaky waveguide, a unique angular signature is derived for each path, whether line of sight, a specular reflection, or an engineered path.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.

在无线局域网（WLAN）中，每秒比特数规模的无线传输已经在商业上可用。例如，最新的60千兆赫兹Wi-Fi标准承诺数据速率高达每秒100千兆比特。该项目的目标是实现数据速率、频谱接入、方向性和空间复用的下一个数量级，目标是具有支持移动的客户端的低延迟控制平面的每秒太比特WLAN。也就是说，将频谱接入扩展到太赫兹将为实现第六代无线网络提供关键因素。因此，该项目将导致一个WLAN架构的设计，实施和概念验证演示，使用频谱从100千兆赫兹到500千兆赫兹，范围超过100米。该项目的目标是通过以下综合研究重点，为移动的客户端扩展多流数据速率到每秒太比特。第一个项目推力为从100 GHz到500 GHz的可操纵和高度定向的波束提供了两个基础构建模块：（1）将开发第一种像素化超表面波导，以通过元元件的电气开关动态地操纵THz波束。 (2)太赫兹泄漏波导的耦合频率和转向角的独特属性将首次被利用，以提供频率选择性自适应波束转向。第二个项目的目标是扩展到高密度的用户群体。首先，将开发新的智能反射表面，这将使工程非镜面非视线路径。这一推力将通过实验研究不同建筑组件下可实现的网络密度，确定在太赫兹尺度下将许多同时物理链接打包到有限空间区域的经验限制。第三个项目的目标是提供不间断的Tb/sec规模的通信，即使在用户和环境移动的存在。该项目的方法旨在通过每个发射和接收角度的新颖频谱特征将控制平面扩展到大型密集的移动的WLAN。也就是说，通过泄漏波导发射的太赫兹彩虹，每个路径（无论是视线、镜面反射还是工程路径）都可以获得独特的角度特征。该奖项反映了NSF的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评估，被认为值得支持。
