# Future Industrial Applications: Exploring LPWAN-Driven IoT Protocols
## 5 Industrial Application Perspective
### Work Safety  
Many security policies exist for enhanced security for IIoT risk management and control security principles. Furthermore, the IIoT energy system can detect defects and energy usage of different components by continuous monitoring and real-time data processing. As a result, the system can prevent severe and harmful accidents and wasteful losses while also increasing overall energy efficiency. Monitoring and response systems can be well suited to long-range and low-power IoT protocols like LPWAN [133]. [PERSON] et al. [134] implemented a low-powered smart alert system for the safety of mine workers using LoRaWAN. It is efficient in reducing death rates and disease by constantly observing the environment and alerting the workers about any potential danger. This system efficiently and economically obtains the mine worker's medical data, which are then utilized for additional artificial-intelligence-based medical prognosis. On the other hand, new technology such as RedCap is suitable for CCTV video surveillance cameras with <500 ms latency with a 2-4 Mbps data rate, although high-end video, like smart farming, demands higher performance [34]. Table 3 summarizes the relevancy of the different IoT protocols from an application perspective to point out which protocol is suitable for certain usage criteria. In Table 4, we summarize some case studies conducted in countries in Asia, Australia, Europe, and South America to show practical usage of the protocols. The studies were conducted  
in both indoor and outdoor environments. In most cases, LoRaWAN was used to utilize IoT networks. \begin{table}
