How to view wireless router radiation problems

With the development of wireless routing, users are also very concerned about the problem of wireless router radiation. As household electronic products become more and more abundant, wireless router radiation testing, many users are paying attention to the physical harm caused by the radiation of wireless routers. Among these products, wireless products pose the greatest pressure on users. Some users do not even dare to use wireless products.

In the book, don't be alarmist! In this article home computer radiation secrets, we have learned that home computer products have very low harm to human body, but are wireless products very big? As mentioned above, many users question it and how much harm it has to people's health? The purpose of this article is to solve this knot for users. Should we use wireless connection? Wireless products, gradually become the mainstream of the family is definitely a wireless router, so the test using the market share of the highest TP-LINK products, models for TL-WR841N, is a dual antenna 802.11n wireless routing, the test site is in the Electromagnetic Environment Laboratory of the Institute of Biological, energy and environmental measurement science and measurement technology, the Chinese Emy of metrology, which is responsible for formulating national environmental security standards for electronic products. We will test the three statuses of wireless router shutdown, standby, and working. Let's take a look at the test standards.

Many users think that the higher the power, the greater the radiation of the East-West Wireless Router, is actually not accurate. We are measuring the radiation intensity of a wireless router. The electric field measuring instrument is used. The measurement units are: Electric Field Intensity V/m ), this value shows the harm of electric waves to the human body. How powerful an electric field is harmful to the body? How strong is the magnetic field harmful to the body? Our country has no relevant standards in this regard. During the test, our engineers in the laboratory recommended that we refer to the European Union's reference level, which is applicable to the general public under the exposure of time-varying electric fields and magnetic fields.

For wireless routing products, we need to refer to the electric field strength E, the corresponding frequency is 2-300 Ghz, this red number 61 is the reference standard, if the number of tests exceeds 61, it indicates a high risk to human health. If you pay attention to it, you will find that we do not use the expression 'harmful to the human body if the value is greater than xx. The World Health Organization explained the standards promulgated by the European Union: "It is important to distinguish between health hazards and health risks. A hazard is an item or environment that may damage a person's health. Risk is the possibility or probability that a person will be affected )."

This is like the difference between riding a bike and taking a plane. If a bike falls down, it will not die. If the plane falls down, it will not be able to survive. The risk of taking a plane is much greater than riding a bicycle, and it does not mean that the plane will die. In addition, individual differences are also a factor that cannot be ignored. Some people get drunk when drinking half a bottle of beer, while others get sober when drinking one bottle of Erguotou. Therefore, it is unscientific to list a number directly to tell everyone that it is harmful, the above figures represent only risk values.

The first one is closely following the wireless router, and the other is simulating normal use at a location 1 meters away from the router, distance from the user to the vro ).

The following tests are based on these two points: When the router is shut down, the standby mode is used, and when the router is working at full capacity, we will compare the tests with the mobile phone products, let you know more about the radiation of a wireless router. The RMS value under the instrument is a valid value. When the router is off, the values of both test points are below 0.2 V/m. It can be said that this value is almost zero.

After the vro is enabled, the two laptops are connected both wired and wireless. There is no data transmission at this time, so the field strength is tested during the standby mode. The field strength value cannot be added. That is to say, the field strength at this time minus the field strength when the router is shut down. Compared with mobile phones, the wireless router products we tested are still quite secure, with only 5 V/m at full load, far below the EU standard 61 V/m.

The article is coming to an end. I believe many of my friends have put down their hearts and minds. How can we use wireless routers more than one meter at ordinary times, therefore, the "wireless router radiation" that users understand can be completely ignored, and we are still testing 802.11n products, the mainstream 54M products will be lower. In the last sentence, if you can accept the "wireless router radiation" of your mobile phone, the impact of WIFI products on your health will be insufficient, so you can use it with peace of mind.
