In the field of IIoT, Industrial Wireless Router is a core device that connects the physical world with the digital world. Its stability and reliability are crucial for the operation of the entire system. However, with the increasing attention to electromagnetic radiation, how to reduce its radiation impact while using Industrial Wireless Router has become a concern for many users. As a senior R&D engineer in the Industrial Internet of Things, this article will explore the source and impact of radiation from Industrial Wireless Router as well as strategies to reduce it.

1. Source of radiation from Industrial Wireless Router
   During operation, the Industrial Wireless Router will generate certain electromagnetic radiation. This radiation mainly comes from the working state of its internal circuit, especially when the router is performing data transmission and signal emission operations. Although the radiation dose of Industrial Wireless Router is usually within the safety range stipulated by the state, long-term exposure to high-intensity radiation may still have potential effects on human health.

2. The impact of radiation from Industrial Wireless Router
   ①. Effects on the human body
   Long-term exposure to electromagnetic radiation may cause a series of discomfort symptoms in the human body, such as dizziness, fatigue and listlessness. Although there is currently no conclusive evidence that the radiation from Industrial Wireless Router will cause direct harm to human body, it is still necessary to remain vigilant and take appropriate measures to reduce exposure.
   ②. Impact on electronic devices
   The radiation of Industrial Wireless Router may also interfere with nearby electronic devices and affect their normal operation. This interference may be more pronounced, especially in high-density electronic equipment environments.

3. Strategies for reducing radiation from Industrial Wireless Router
   ①. Optimize router location
   Placing the Industrial Wireless Router away from human bodies and other sensitive devices can effectively reduce the impact of radiation on the human body. It is recommended to install the router at a certain height above the ground and in a well-ventilated place, avoiding placing it directly near the bed or human body.
   ②. Adjust the power of router
   Without affecting normal use, reducing the transmission power of Industrial Wireless Router appropriately can reduce its radiation. Users can adjust the power through the router's management interface, or choose a router product with automatic power adjustment function.
   ③. Use shielding materials
   Using shielding materials such as metal plates or electromagnetic shielding nets around the router can effectively block the transmission of electromagnetic radiation. However, it should be noted that this method may affect the signal coverage and transmission quality of the router, so a trade-off needs to be made based on actual conditions.
   ④. Turn off unnecessary wireless functions
   If the Industrial Wireless Router supports turning off wireless functions such as Wi-Fi and Bluetooth, you can turn them off to reduce radiation when a wireless connection is not required. In addition, it is also possible to consider using wired connections instead of wireless connections to further reduce radiation exposure.
   ⑤. Regular inspection and maintenance
   Regularly check and maintain the Industrial Wireless Router to ensure that its internal circuit and cooling system are in good condition. Aging circuits and poor cooling systems may lead to increased radiation from routers, so timely replacement of damaged components and cleaning of the cooling system are important for reducing radiation.
   ⑥. Choose compliant products
   When purchasing Industrial Wireless Router, you should choose a compliant product that meets national or industry standards. These products are usually subjected to strict radiation testing and quality certification, with a reasonable level of radiation that has little impact on human health.

4. Summary and outlook
   As an important part of the industrial Internet of Things, Industrial Wireless Router's radiation problem cannot be ignored. By optimizing the location of routers, adjusting power levels, using shielding materials, turning off unnecessary wireless functions, conducting regular inspections and maintenance, and selecting compliant products, we can effectively reduce the radiation impact of Industrial Wireless Routers. In the future, with the continuous progress of technology and improvement of standards, we believe that more innovative solutions will emerge to better protect human health and environmental safety. At the same time, we also call on users to be vigilant and rational when using Industrial Wireless Router, and respond scientifically to radiation issues.
