Wireless communication technologies in industrial internet of things networks

The industrial Internet of Things forms the basis for future smart plants which are digitized, flexible manufacturing facilities with a rapidly changing output layout and numerous mobile participants. Through the Internet of Things, data are collected from various sources using smart devices and transmitted to the management system for analysis and decision-making purposes. Reliable and secure communication networks, including wireless networks, are essential for such production. This article discusses advanced wireless data transmission technologies used in industrial IoT networks, specifically 5G, WLAN, and LoRaWAN. While there is a wide range of options available, each technology has its own strengths and limitations, making it suitable for different use cases. In particular, advanced generations of wireless technologies deserve special attention. For cellular communications, this is 5G; for WLAN, it is Wi-Fi 6 (IEEE 802.11AX).
