Abstract

The 6G technology promises significant innovations for Industrial Internet of Things (IIoT) devices, in Industry 4.0 and beyond. To ensure continuous communication and real-time data collection, these devices will need to be deployed in increasingly challenging environments. This article explores the role of Intelligent Reflecting Surfaces (IRS), also known as metamaterials. This technology consists of an array of backscattering elements that can be individually adjusted to generate phase shifts in signal reflections, allowing for active control of signal propagation properties and promoting the creation of an intelligent radio environment. The phase control of IRS, combined with conventional transmission control, has the potential to improve performance compared to wireless networks without this technology. Additionally, ambient backscattering shows promise for providing continuous energy to IIoT devices via electromagnetic waves. Any communication inconsistencies can be corrected using Software-Defined Metamaterials (SDM). This work analyzes the integration of programmable wireless environments with metamaterials to establish favorable electromagnetic backscattering, ensuring uninterrupted communication and energy efficiency (EE).
