智能无线电环境展望:表面波通信高速公路

A Vision to Smart Radio Environment: Surface Wave Communication Superhighways

Kai-Kit Wong, Kin-Fai Tong, Zhiyuan Chu, Yangyang Zhang

摘要:

作为对传统方法的补充,传统方法集中在收发器设计上,以最大限度地利用不稳定的有损衰落信道,最近出现的无线通信中的一个根本性发展是通过使用软件定义的材料或可编程元表面来建立有利的传播条件来追求智能无线电环境。本文描绘了未来智能无线电环境中表面波(SW)在“智能表面”上传播的通信高速公路的愿景。该概念不同于在大表面上使用无源元件以智能地朝向预期用户终端反射无线电波的主流努力。在这一愿景中,由于与自由空间传播相比路径损耗小得多,能源效率将是超高的,并且SW固有地局限于智能表面的事实不仅大大简化了干扰管理的任务,而且还使异常本地化的高速无干扰数据访问成为可能。我们将概述软件范式带来的机遇和相关挑战。我们还将试图阐明几个关键的使能技术,使这一点成为现实。将讨论的一个重要技术是软件控制的流体波导架构,允许动态创建高吞吐量的数据高速公路。

英文摘要:

Complementary to traditional approaches that focus on transceiver design for bringing the best out of unstable, lossy fading channels, one radical development in wireless communications that has recently emerged is to pursue a smart radio environment by using software-defined materials or programmable metasurfaces for establishing favourable propagation conditions. This article portraits a vision of communication superhighways enabled by surface wave (SW) propagation on "smart surfaces" for future smart radio environments. The concept differs from the mainstream efforts of using passive elements on a large surface for bouncing off radio waves intelligently towards intended user terminals. In this vision, energy efficiency will be ultra-high, due to much less pathloss compared to free space propagation, and the fact that SW is inherently confined to the smart surface not only greatly simplifies the task of interference management, but also makes possible exceptionally localized high-speed interference-free data access. We shall outline the opportunities and associated challenges arisen from the SW paradigm. We shall also attempt to shed light on several key enabling technologies that make this realizable. One important technology which will be discussed is a software-controlled fluidic waveguiding architecture that permits dynamic creation of high-throughput data highways.
