Time-Critical IoT Applications Enabled by Wi-Fi 6 and Beyond

Wireless Industry 4.0 applications typically have stringent latency and reliability requirements. Even though state-of-the-art Wi-Fi networks can reliably achieve single digit milliseconds latency, new emerging time-critical applications have requirements that current Wi-Fi cannot meet. In this paper, we present next generation Wi-Fi technologies and describe how they can be leveraged to enable three time-critical Industry 4.0 use cases: wireless industrial automation control, remote rendering in extended reality applications and cooperative simultaneous localization and mapping using autonomous mobile robots in a factory plant.
