Mechatronic Reconfigurable Intelligent‐Surface‐Driven Indoor Fifth‐Generation Wireless Communication

Abstract

Reconfigurable intelligent surface‐assisted wireless networks have been proposed to overcome the current technical issues in fifth‐generation (5G) wireless communication systems. Generally, the beam control functions of a reconfigurable intelligent surface require the independent phase control of the unit cells, and each unit cell requires an active device. Although reconfigurable intelligent surfaces are considered a promising solution for 5G and sixth‐generation (6G) wireless communication, their practical implementation faces a bottleneck at high frequencies (e.g., with the millimetre‐wave spectrum) because they require a large number of active devices, leading to high costs, parasitic effects, increased design complexity, and modulated signal distortion. Herein, a mechatronic reconfigurable intelligent surface is reported for indoor millimetre‐wave wireless communication. Our mechatronic device strengthens the innovative reflective beam control functions through rotatable unit structures and rack gear systems. Furthermore, the criteria required for future 5 G wireless communication are experimentally verified by transmitting and receiving quadrature phase‐shift keying 16‐/32‐/64‐quadrature amplitude modulation signals based on 5 G new radio (NR) frequency range two standards for indoor environments.

Programmable metamaterials

“…In industrial community, power consumption is one of the critical measures of real systems. Hence, some low-power-consumption programmable metamaterials are proposed, which commonly use motors to rotate the meta-atom or metamaterial to reconstruct the EM control functionalities (Yang et al, 2021;Xu et al, 2022;Jeong et al, 2022;, or introduce the Kirigami technology to mechanically reconfigure the EM performance (Phon et al, 2022;Zheng et al, 2022).…”

Research on Construction Technology of Communication Mechanical and Electrical Engineering

“…Mechanical and electrical engineering is not only a crucial part of the en- nologies. The construction characteristics of each system have certain differences, and the actual construction points are also different (Jeong et al, 2022;Li et al, 2021). Before carrying out construction work, relevant personnel should conduct on-site surveys, improve and optimize construction plans, and further ensure the smooth progress of mechanical and electrical installation construction.…”

Multifunctional Reflective Metasurface to Independently and Simultaneously Control Amplitude and Phase with Frequency Tunability

“…However, those metasurfaces mostly comprise passive resonator elements without electrical tuning and are unable to switch functionality. [27][28][29][30][31] Electrically tunable metasurfaces are preferred for practical applications compared to other tuning technologies, such as mechanical [32][33][34] or microfluidic [35,36] approaches, due to their fast switching/tuning speed. [37][38][39] Although they have been demonstrated previously, a single metasurface capable of fully controlling amplitude, phase, polarization, and angular frequency has not been reported.…”
