We present a new type of wireless access infras-tructure consisting of a fabric of dispersed electronic circuitsand antennas that collectively function as a massive, distributed antenna array. We have chosen to name this new wireless infrastructure 'RadioWeaves' and anticipate they can be integrated into indoor and outdoor walls, furniture, and otherobjects, rendering them a natural part of the environment. Technologically, RadioWeaves will deploy distributed arrays to create both favorable propagation and antenna array interaction. The technology leverages on the ideas of large-scale intelligent surfaces and cell-free wireless access. Offering close to the service connectivity and computing, new grades in energy efficiency,reliability, and low latency can be reached. The new concept moreover can be scaled up easily to offer a very high capacity inspecific areas demanding so. In this paper we anticipate how two different demanding use cases can be served well by a dedicated RadioWeaves deployment: a crowd scenario and a highly reflective factory environment. A practical approach towards a RadioWeaves prototype, integrating dispersed electronics invisibly in a room environment, is introduced. We outline diverse R\&D challenges that need to be addressed to realize the great potential of the RadioWeaves technology.

RadioWeaves 实现高效连接:实际部署中约束的分析和影响

我们提出了一种新型的无线接入基础设施,由分散的电子电路和天线组成,它们共同作为一个巨大的分布式天线阵列。我们选择将这种新的无线基础设施命名为“RadioWeaves”,并预计它们可以集成到室内和室外墙壁、家具和其他物体中,使它们成为环境的自然组成部分。从技术上讲,RadioWeaves 将部署分布式阵列以创建有利的传播和天线阵列交互。该技术利用了大规模智能表面和无蜂窝无线接入的思想。提供接近服务连接和计算的能力,可以在能效、可靠性和低延迟方面达到新的水平。此外,新概念可以轻松扩展,以提供非常高的容量,在特定领域有如此要求。在本文中,我们预计专用 RadioWeaves 部署如何能够很好地满足两个不同的要求苛刻的用例:人群场景和高度反射的工厂环境。介绍了一种实现 RadioWeaves 原型的实用方法,在房间环境中无形地集成分散的电子设备。我们概述了需要解决的各种研发挑战,以实现 RadioWeaves 技术的巨大潜力。引入了在房间环境中无形地集成分散的电子设备。我们概述了需要解决的各种研发挑战,以实现 RadioWeaves 技术的巨大潜力。引入了在房间环境中无形地集成分散的电子设备。我们概述了需要解决的各种研发挑战,以实现 RadioWeaves 技术的巨大潜力。
