How much radiation does the router have?
Yuan Yuming, director of Beijing Environmental Science Society, found that the maximum instantaneous radiation of wireless router is 0.2 W/m2 in working state and only 0.01w/m2 in standby state. Half a meter away, the radiation of the wireless router decays quickly, and the value at this time is similar to that of the daily use of 3G mobile phones.
Another experiment by Beijing Institute of Metrology and Testing tells us that even if the home wireless router is worn on the head, the radiation value will not exceed the standard. When the experimenter placed two routers only 1 cm away from the measuring equipment, the peak value of electromagnetic radiation was 4.7 to 4.2 volts per meter, while the national limit of electromagnetic radiation was 12 volts per meter, which was far below the safety standard. However, Yuan Yuming also reminded everyone that although two experiments have proved that wireless routers will not cause harm to human body, it does not mean that all such devices are safe. Some substandard equipment may also threaten human health, so there is nothing wrong with paying attention to safety when conditions permit.
Experts suggest that the wireless router should be placed half a meter away from the human body, and the power can be turned off when not in use; Try to avoid the radiation superposition effect caused by the simultaneous use of radiation equipment such as mobile phones and microwave ovens.
Is the wireless router a big radiation to people?
Common sense of wireless network: wireless radiation and comparison
With the progress of society, people pay more and more attention to the quality of life and living environment, and the problem of environmental pollution has attracted more and more attention. People have seen the free experience brought by wireless internet access. At the same time, some friends asked whether wireless radiation has radiation on human body. Whether the various symptoms of radiation will gradually appear in a few years can not help but make people feel a little worried when experiencing wireless Internet access. The author will talk to you about this problem today.
Distinguish between two concepts
First of all, we must distinguish between electromagnetic radiation and electromagnetic pollution. Electromagnetic radiation is everywhere, everywhere. Only when the energy reaches a certain value will electromagnetic radiation become electromagnetic pollution and cause harm to human body. A small amount of radiation can completely offset the influence of the human body's own adjustment ability. Appropriate electromagnetic radiation is not only harmless to people, but also beneficial to people.
Compared with the same kind, it is almost "one machine" now. Whether you are GSM, CDMA or PHS, there are electromagnetic radiation problems. If you dare to use them with confidence, then you can use wireless devices with more confidence, because the above-mentioned devices have far more radiation to the human body than wireless devices. Let the data speak for itself.
At present, the maximum transmission power of GSM mobile phone in 900MHz band is 2W, and the maximum transmission power in 1800MHz band is 1 W, which is higher than normal when the mobile phone is connected. Let's call it 700 MW CDMA, a so-called green mobile phone, is actually not environmentally friendly. We have a wrong understanding that CDMA mobile phones will not interfere with the surrounding telephones, speakers and screens when answering incoming calls, and come to the conclusion that their radiation is far lower than that of GSM. In fact, according to experts' rigorous tests, the radiation of the two mobile phones is equivalent to that of the human body. Compared with the first two, PHS can really be called a green elf, with a burst transmission power of about 80 milliwatts.
In contrast, the transmission power of WLAN wireless network card is even smaller, generally about 40 MW, and it is far away from the human body. Unlike the mobile phone attached to the body, it reaches the human body less than 1 MW.
A friend suggested that microwave ovens and 802. 1 1b wireless devices are in the same working frequency band, so I am worried that the radiation of wireless network cards is also large, but the power of a microwave oven can reach 700 watts, and there are only a few wireless network cards, so don't worry.
The radiation of another pair of people in a wireless network comes from the wireless AP or wireless router that transmits wireless signals, but the transmission power of the wireless LAN access point AP is generally less than 100 MW, which is only equivalent to 1/5 of the PHS base station. So the impact on people is much smaller.
Summary and some suggestions.
Seeing this, you should believe that wireless internet access will only bring you wireless bondage and free enjoyment, and will not affect the health of you and your family. So, you don't need to worry too much. If you are still worried, I have compiled some suggestions to minimize radiation for your reference.
1. Turn off wireless devices when not in use.
If the wireless router or AP is not used temporarily, the power will be turned off, which can reduce radiation on the one hand and save electricity on the other. In addition, most laptops now have built-in wireless network cards. If you don't use the wireless network, please disable it. The operation method is to right-click my computer, find the wireless network card in the device manager of the properties, and select Disable.
2. Don't use high-power wireless AP indoors.
In order to increase the transmission distance of wireless devices, many manufacturers provide high-power wireless AP, which is generally used outdoors. However, some friends blindly pursue the transmission range and penetration ability, and outdoor AP is used indoors, which undoubtedly increases the radiation of wireless devices to people, which is not desirable.
Don't get too close to your body when surfing the Internet wirelessly.
Some friends experience the fun of wireless internet access, sit casually with a notebook, put the notebook on their lap and start watching movies wirelessly. This way, the wireless network card of the notebook is closer to the body, and the radiation is slightly larger, and it is easy to break the notebook. Try to avoid it.
5. Strengthen physical exercise and enhance self-resistance.
Radiation of the same energy has different effects on different people. People with strong resistance offset much more radiation than people with weak resistance, so we should correctly understand the radiation problem of wireless devices and improve our resistance through physical exercise. ...
Is home wireless router harmful to human body?
There must be. Generally, routers do little harm to human body, so they do not pose a threat. At present, a large number of routers are in use. The radiation of my tp-link wireless router decreases according to the distance. If you route every meter, it will be much less, and the safe distance is 1 and 2 meters.
Compared with sitting in front of a computer and holding a mobile phone in your arms, the radiation emitted by the route is nothing to worry about.
So the landlord doesn't have to worry
Will the wireless router radiate to people when it is placed beside the bed?
Better not put it there. Although the radiation power of wireless routing is not as good as that of TV, it is less than that of mobile phone. But electromagnetic waves are definitely not good if they are too close to each other. Although it is not fatal, biologically speaking, electromagnetic radiation can interfere with cell division. If it is affected during division, it will produce cancer cells, but the probability is very, very small. But it's best not to put it on the bedside. If you sleep there for a few days and feel headache or discomfort, it is likely to happen.
Does the router installed at home radiate much? Is it good for your health after a long time?
If you don't install a router,
Is there no radiation at home?
You take a radio,
Can I receive the radio at home?
Wireless signals are everywhere,
These injuries to the human body,
Can be ignored.
What is the radiation intensity of the wireless router? Is it harmful to human body?

Don't get too close to your body when surfing the Internet wirelessly on your laptop. Some friends experience the fun of wireless internet access. Just sit anywhere with your laptop, put it on your lap and start surfing the Internet and watching movies wirelessly. In this way, the wireless network card of the notebook computer will be closer to your body, and the radiation will be slightly larger, which is easy to break the notebook computer and should be avoided as much as possible. 4. When answering the mobile phone, it is best to use independent headphones and microphones to answer the phone. The electromagnetic radiation released at the moment when the mobile phone is turned on is the largest. Using a separate earphone can avoid close contact with the head at this time and reduce the radiation of the mobile phone to the human body at this time. 5. Strengthen physical exercise and enhance your own resistance. ......
Does the WIFI sent by the computer router have great radiation to the human body? What effect does it have on the human body in the long run?
To be sure, wireless routers are radioactive. For computer products, most products have radiation, such as computers, mobile phones, microwave ovens, electronic products and other electrical appliances that we commonly use. Almost all electronic products can be said to have radiation, but the radiation intensity is higher than low, and too low radiation can be ignored.
When it comes to wireless routers, residents with multiple computers at home will be familiar with them. As long as they buy it and install it at home, all the computers in the family can access the Internet wirelessly at the same time. More and more mobile phones can use this function, such as wifi wireless Internet access, tablet computers, notebooks and other familiar wireless Internet access. The coverage of wireless network is generally effective within tens of meters, which means that a wireless router is installed at home, and the whole family is within the coverage of wireless network. Many family members have issued such questions: "The whole family has signals, and the radiation should be quite small. Will it affect the health of children or pregnant women? " The result of appraisal by authoritative department is: "The radiation of wireless router is very small, much smaller than that of mobile phone", which means that the radiation intensity is within the acceptable range of human body, so it can be said that the radiation of wireless router is not large and relatively safe.
Is the wireless router radiating heavily?
The test data of authoritative safety inspection department shows that the electromagnetic radiation generated by wireless router is stable within 4mG (milligauss), and occasionally high value may be interference, and the radiation is within 2mG after leaving the router 50cm. Under this working condition, the radiation connected to and disconnected from the computer increased slightly, but there was no statistical significance. Compared with the electromagnetic radiation of electromagnetic stoves, microwave ovens and mobile phones, the electromagnetic radiation of wireless routers is still relatively small. When the microwave oven works, the radiation reaches 130-360 mg, and it can only be reduced to 2mG when 1.5 meters away. When the mobile phone is on standby, the electromagnetic radiation is only 2mG, but when you call someone, the instantaneous radiation dialed by the mobile phone reaches 50- 100 mg, and it returns to normal after three or four seconds.
Wireless router radiation test data
After reading the above report about the radiation intensity of wireless routers, I believe many friends are relieved. We usually use wireless routers at a distance above 1 m, so users' understanding of "radiation" can be completely ignored, and we are still testing 802. 1 1n products, and the mainstream 54M products will be lower. Finally, to sum up, if you can accept the "radiation" of mobile phones, then WIFI products have little impact on your body and can be used with peace of mind. Finally, I need to remind you that some wireless network cards on the market radiate a lot, which exceeds the human safety tolerance standard. Internet access is also cheaper at present. I suggest you don't use any high-power network card to crack other people's wireless networks. Safety first!
Wireless routing is close to me. Is there any radiation hazard?
Although the wireless network has radiation, this radiation is very small, so don't worry. The radiation of wireless network is only nine Niu Yi hairs to your computer. If you don't care about the radiation of the computer, then there is no need to care about the radiation of wireless WIFI. However, if you use a high-power network card receiver or a high-power wireless WIFI transmitter, it means that the high-power radiation is still very large, and it is not harmful to the WIFI laptop of ordinary families.
