Excuse me, is there radiation living near the TV station?

Since the emergence of mobile communication, people have been talking about radiation. In this regard, the state has also done a lot of popular science propaganda. "The communication equipment used in the network strictly meets the national environmental protection standards. When building a base station, the operating company will also conduct an environmental assessment of the radiation around the base station. "

In fact, most people can treat base station construction rationally. According to media reports, in the "warm tips" on base station radiation posted by the above-mentioned residential properties, many owners who support the setting of signal equipment expressed their views with pens. "You don't need the Internet, we need to use it."

Some experts said in an interview with Zhongxin.com. Com, "what has no radiation? The radiation of mobile phones and computers is serious, and the radiation of base stations is within a certain range. As long as the communication service is used normally, the impact on health can be ignored. "

In fact, everyone can't do without the construction of base stations. Users' mobile phones can surf the Internet anytime and anywhere without a base station continuously invested by telecom companies, because if the base station is not nearby, the mobile phone will basically be useless. Adding base stations is also for better signal coverage.

Extended data

Many people can speak a little, but not all. It is this little knowledge that makes people contradict and misread electromagnetic waves. Just like air, electromagnetic waves exist around each of us. Only by understanding it and mastering it can we really live in harmony with electromagnetic waves, just as human beings gradually learn to live in harmony with nature.

Modern people live in an electromagnetic environment every day. Lightning strikes, sunspot activities, the atmosphere, the universe and so on will all produce electromagnetic waves, which are electromagnetic waves from nature.

The electromagnetic waves of human society come from radio transmitting equipment, industrial equipment and medical equipment, such as radio stations, hand-held mobile phones, AC high-voltage transmission lines, fluorescent lamps, microwave ovens, televisions, computers, base station antennas and so on.

In fact, anywhere on the earth, no matter day or night, there are various electromagnetic waves with different frequencies and intensities, which are invisible, intangible and inaudible.

With the science and technology of modern life, electromagnetic radiation is more and more around people, but its influence and harm to human body is not as terrible as people think. Taking the mobile communication base station as an example, people often question the influence of electromagnetic radiation of the base station on the environment because of its large target.

However, the design of any stage of the mobile communication engineering construction scheme has undergone strict environmental protection design and evaluation.

China's communication base station standards strictly meet the requirements of national standards, with electric field intensity far less than 12 V/m and power density far less than 40 MW/cm2. In the mobile communication frequency band (800MHz-2 100MHz), China's electromagnetic radiation standard is stricter than the recommended standard of international non-ionizing radiation standard 1 1.25-26.26.

The intensity of electromagnetic radiation is inversely proportional to the square of distance. Compared with the distance of 10 meter, the intensity of electromagnetic radiation is reduced by 100 times. In addition, if electromagnetic radiation passes through walls and other objects, the radiation intensity will also drop sharply. If the base station is built on the roof of a residential building, it will not have any impact on the residents in the building.

With the advent of 3G and 4G era, TD base stations use smart antennas, which have smaller transmission power and smaller actual radiation, far lower than computers, microwave ovens and televisions.

More importantly, many people don't realize that the more reasonable the base station density, the lower the radiation intensity of mobile phones to people. There is an intelligent control mechanism between the mobile phone and the base station to dynamically adjust the communication channel and electromagnetic radiation power between them.

A communication base station with a coverage radius of 500 to 700 meters, relative to the mobile phone within this range, the farther away from the base station, the stronger the peak transmission power of the corresponding channel and mobile phone. When the mobile phone is talking in a building about 700 meters away from the base station, the peak emission of the mobile phone is about 2 W. ..

When the mobile phone moves to a viewing distance of 200 meters from the base station 1, the corresponding channel transmission power between the base station and the mobile phone will be automatically adjusted to about 0. 1W, respectively. That is to say, when the density of base stations is high, the corresponding transmission power between each base station and the mobile phone will become low. If the number of base stations is not enough, the transmission power of mobile phones will increase, which will have a bad influence on human body.

Therefore, the more reasonable the density of mobile communication base stations is, the safer the mobile phone is for callers during use.

Because of the base station on the roof, people can communicate smoothly. Base station facilities are also one of the most basic facilities in modern society. Today, mobile communication is as common as water and electricity. It is the ordinary people themselves who benefit from the scientific understanding of electromagnetic radiation and mobile communication facilities, while enjoying the convenience brought by modern communication, protect these infrastructures to facilitate their lives.

People's Network-Is there radiation after adding a base station to the community? The Ministry of Industry and Information Technology has reached a conclusion.

People's Network-Tell you the truth about the electromagnetic radiation of the base station.
