Abstract

Wi-Fi promises to revolutionize wireless connectivity through the integration of time-sensitive networking (TSN) capabilities, ensuring low latency and unmatched reliability within license-exempt spectrum bands. This study delves into the seamless amalgamation of TSN functionalities with Wi-Fi, with a particular focus on its implications for Internet of Things (IoT) applications, notably industrial automation and collaborative robots. In this paper, we examine diverse network configurations to assess their impact on latency and reliability in industrial automation scenarios. Furthermore, the efficacy of prioritization, preemption, and credit-based shaping policies is evaluated to optimize time-sensitive traffic management and enhance overall performance. The findings highlight Wi-Fi’s enhanced suitability for industrial automation, showcasing how collaborative robots can leverage reduced latency and real-time communication to achieve heightened precision, safety, and seamless human-robot interaction. By considering several network setups and traffic shaping policies, this paper provides invaluable insights for industrial practitioners and researchers, shedding light on the potential impact of Wi-Fi in industrial automation and collaborative robotics domains.
