Long-range, low-power networks are quickly gaining traction in the Internet of Things (IoT) due to their potential to handle long-range sensing and control applications at a reasonable cost. Wireless communications have now spread throughout the universe. Wireless sensors and Internet of Things (IoT) applications can result in useful applications. In IoT applications, traditional wireless solutions such as mobile signals and data transmission play a vital role. Bluetooth, ZigBee, Wi-Fi, and a slew of other application-specific wireless protocols are currently available. This article examines the most recent wireless technology for IoT, namely LoRaWAN, an application-specific wireless protocol. The LoRaWAN Network is a low-power radio network for IoT devices. In the realm of industrial automation, there is an IoT strategy that is paving the way for novel services to improve the efficiency, dependability, and availability of industrial processes and goods. The LoRaWAN technology is discussed in this study, thanks to its widespread adoption in both the industrial and academic spheres. This paper also discusses a few LoRaWAN applications.
