Wireless Network radiation is not terrible. Then we can talk about security.

Mobile phones have been proved to be quite radiant. Long-term use may endanger our health. Many people have noticed this problem. Wireless networks also have radiation, so how can we prevent it?

Radiation is harmful to the elderly, children, and pregnant women

During the use of wireless networks, wireless routers, Wireless AP and other devices emit electric waves all the time. High-dose electromagnetic radiation will affect and damage the original biological current and biological magnetic field of the human body, causes an exception to the original electromagnetic field in the human body. It is worth noting that different people or the same person have different capacities for electromagnetic radiation in different age groups. The elderly, children, and pregnant women are sensitive to electromagnetic radiation, weak resistance should be our key protection targets.

Wireless Network radiation is actually very weak.

The radiation size mainly depends on the transmit power. China Radio Management Board stipulates that the transmit power of Wireless LAN products cannot exceed 10 mW, while the standards in other countries are relatively loose, for example: the maximum transmit power of Wireless LAN products in Japan is 100 mW, and that of some countries in Europe and America is about 50 mW. Currently, products sold on the market generally comply with the standards of European and American countries. When the power of a mobile phone is high, it can reach more than. The transmit power of most wireless routers is also 50 mW ~ 100 mW, while the power of the wireless network adapter is generally less than 10 mW.

Replacing a high-gain antenna will not increase radiation

Currently, for wireless network products on the market, the antenna gains are generally 2dBi and 3dBi. To expand wireless signals, some users prefer to replace high-gain antennas. Because the antenna is a passive device and does not increase the power, no matter how large the gain is, the transmit power will not be higher than 50 MW. The transmit power mainly depends on the transmit hotspot, that is, wireless routers and wireless APs. as long as their power meets the security standards, you can replace high-gain antennas with confidence.

Mechanism of radiation hazards to human body

Thermal Effect: more than 70% of the human body is water, and water molecules are rubbed against each other after electromagnetic radiation, which causes the body to heat up and affects the normal operation of organs in the body.

Non-thermal effect: the organs and tissues of the human body have weak electromagnetic fields. They are stable and orderly. Once they are disturbed by external electromagnetic fields, the weak electromagnetic fields in the equilibrium state will be damaged, the human body is also damaged.

Cumulative effect: After the thermal effect and non-thermal effect are applied to the human body, the damage to the human body has not been repaired. What is previously referred to as the endurance of the human body-Internal Force Majeure), if the human body is subject to electromagnetic radiation again, the damage level will accumulate, and it will become permanent pathological and life-threatening for a long time. For groups that have long-term contact with electromagnetic radiation, even if the power is very small and the frequency is very low, unexpected lesions may also be induced and should be vigilant.

How to avoid the harm caused by wireless radiation

The radiation of the wireless network depends on the transmit power. The more the radiation from the wireless launch point, the more intense the radiation. Therefore, the wireless routing and Wireless AP should be placed farther away from people, it is also far away from the bedroom. Try to avoid the close distance between the elderly, children and pregnant women, and long-term access to wireless routers and other devices. The power should be turned off before going to bed at night. In addition, avoid wireless products from being too close to audio, television and other electronic devices to prevent interference from producing other radiation. As long as you keep a long distance to avoid the cumulative effect caused by long-time living in the wireless network environment and develop good habits, there should be no problem.
