The rapid evolution of Industry 4.0 has necessitated a paradigm shift from traditional "best-effort" networking to deterministic communication frameworks capable of supporting ultra-reliable low-latency communication (URLLC). Time-Sensitive Networking (TSN) has emerged as the foundational set of standards to provide these guarantees over Ethernet; however, the modern industrial landscape increasingly demands mobility and flexibility, shifting the focus toward wireless integrations. This research article provides an extensive investigation into the convergence of wired TSN standards with emerging wireless technologies, specifically 5G and IEEE 802.11be (WiFi 7). By analyzing the mechanisms of precise clock synchronization, scheduled traffic enhancements, and the impact of cyber-physical threats on synchronization stability, this paper establishes a holistic framework for next-generation industrial networks. We explore the architectural shifts from domain-specific E/E architectures in automotive sectors to zonal controllers and the integration of fault-tolerant dual-core lockstep systems. Furthermore, the paper delves into the security vulnerabilities inherent in the Precision Time Protocol (PTP), evaluating the impact of delay-box attacks and internal malicious actors on network integrity. Through a deep theoretical synthesis of current standards and empirical observations from recent literature, this study identifies the critical gaps in cross-layer synchronization and provides a roadmap for achieving microsecond-level jitter in heterogeneous wireless-wired industrial environments.
