Periodic Control Traffic Support in a Wireless Time-Sensitive Network

Time Sensitive Networking (TSN) is being utilized for industrial deterministic applications. Machine control is an example of such applications, which requires high reliability, low and deterministic latency. Currently, such requirements can only be met by wired networks that do not offer the wireless flexibility. For supporting TSN in end-to-end wired-wireless networks, TSN features need to be presented in the wireless network domain as well. In this demo we show the ability of wireless TSN (W-TSN) to support periodic machine control traffic with low latency under other background traffic in the network. We demonstrate time synchronization and scheduling mechanisms in a wireless setting by employing a control loop (a system to balance a ball in a canal) scenario where the time-critical traffic maintains the required latency under scheduled case. This will be demonstrated in a setup composed of imec's W-TSN evaluation kit built on top of the openwifi SDR platform.
