Concept of a TSN to Real-Time Wireless Gateway in the Context of 5G URLLC

Wireless real-time communication protocols enable lots of use-cases within Industry 4.0. As one of the three main components of the upcoming 5G advertises, Ultra-Reliable Low-Latency Communication (URLLC) should achieve a latency below 1ms. URLLC is part of release 17 of the 3GPP and is currently in specification which should be finished within 2022. Nevertheless, other wireless real-time technologies exist and can already be used for some of the use-cases. In the field of wired real-time communication, Time-Sensitive Networking (TSN), as an open-standard solution, is currently in development, after most of the standards have been released recently. The vision of moving the control of Cyber Physical Systems (CPS) into the cloud requires a combination of wireless and wired real-time communication. This paper investigates current wireless real-time technologies and presents first thoughts on a gateway to connect TSN with other wireless technologies.
