Research on network interference problems in intelligent manufacturing

Abstract As the smart manufacturing industry continues to grow, ensuring high-quality data transmission has become especially critical. In wireless communication networks, numerous sources of interference exist, especially significant in restricted space environments such as factories. These areas are subject to signal interference from same-frequency devices and interference from multipath propagation due to signal reflection in buildings. In order to guarantee the communication quality of smart manufacturing systems, reducing network interference in such spaces is a prerequisite; therefore, it becomes crucial to reduce various network interferences. In this study, a scheme combining orthogonal frequency division multiplexing (OFDM) and multiple-input multiple-output (MIMO) techniques is proposed to cope with the interference problem of the network in the smart manufacturing process.
