Abstract
Converged wired and wireless networks promise to meet both real-time and mobility requirements of factory automation scenarios. Time-Sensitive Networking (TSN) and 5G are auspicious technologies for future industrial communication. Hence, the combination of both wired and wireless communication is extensively discussed for industrial use cases. In this paper, we analyze the time synchronization in realistic wired and converged wired and wireless networks through IEEE 802.1AS. We provide a formulation of the time synchronization mechanisms and a system model for IEEE 802.1AS. Moreover, we investigate the synchronization accuracy for TSN and 5G/TSN networks given the requirements from IEEE, 3GPP, and IEC/IEEE.
