The transition to Industry 4.0 is transforming manufacturing through smart, autonomous, and highly interconnected systems that demand ultra-low latency, high reliability, and deterministic communication. Emerging technologies such as Wi-Fi 7 (IEEE 802.11be) and Time-Sensitive Networking (TSN) offer promising capabilities to meet these requirements. Wi-Fi 7 enhances wireless performance with features like Multi-Link Operation (MLO), 320 MHz bandwidth, and improved Quality of Service (QoS), while TSN enables deterministic Ethernet communication through precise time synchronization and traffic scheduling. This paper proposes a scalable ITOT converged architecture that integrates Wi-Fi 7 and TSN to support high-throughput, low-latency, and timesensitive communication, enabling reliable mobility and seamless interoperability across industrial systems. Realworld evaluations in a factory environment demonstrate the higher performance and robustness of the proposed solution, providing practical guidance for deploying TSNintegrated Wi-Fi 7 networks in smart manufacturing.
