Analysis of the Applicability of IEEE 802.11ax Wireless Networks in Industrial Internet of Things and Smart Warehouses Scenarios

Industry 4.0 aims to fully digitalize production processes, and wireless technology plays a significant role in this process. Specifically, for applications such as smart warehouses where robots perform tasks and monitor their progress, modern standards and proprietary solutions must meet stringent industry requirements. One of the primary research goals in this area is to develop wireless systems that can efficiently transmit short data packets in multi-user settings. However, existing proposals and industrial channel models may not always satisfy these demands. To address this issue, the authors suggest optimizing the IEEE 802.11ax standard by utilizing OFDMA (Orthogonal Frequency Division Multiple Access). This optimization can create a highly efficient system for smart warehouses. This article presents a wireless solution for intelligent warehouses based on the IEEE 802.11ax standard, which has the potential to meet the requirements of Industry 4.0. The system includes optimization at two levels: the MAC (Medium Access Control) and PHY (Physical Layer).
