Previously, the suggestion that 5G microwaves are harmful to health caused heated discussions on the Internet. According to the planning of the Ministry of Industry and Information Technology, China will start 2019G network construction in 5, and 2020G commercial services will be launched as soon as 5. So, will the communication base station in the 5G era radiate more?
1. 1. The more communication base stations, the greater the radiation?
In fact, the radiation of the communication base station is not as large as that of a room full of household appliances.In life, microwave ovens, computers, televisions, hair dryers, radios and other household appliances also produce electromagnetic radiation. Compared with these commonly used household appliances, the amount of radiation from cell base stations is minimal. Because the radiation coverage area of the communication base station antenna is wide, the radiation power is dispersed in an area of several square kilometers, and the distance from the human body is often more than 10 meters, and the impact on the human body is small.
2. Is the closer to the communication base station, the greater the radiation?
The radiation of the communication base station belongs to “black under the lamp”, and the distance is not necessarily large. Many citizens believe that the closer to the communication base station, the greater the radiation, so they oppose the construction of communication base stations in their own communities or on the roofs of buildings. In fact, the electromagnetic waves of the communication base station are mainly emitted in the horizontal direction, and the weakness is obvious in the vertical direction, so the power density is often the smallest directly below the base station. Just like an “oil lamp”, the darker it is under the lamp, the brighter it is outward.
3. 4G or 5G communication, which base station has more radiation?
Network acceleration has nothing to do with base station radiation value-added.4G and 5G networks are faster, not by increasing the signal transmission power of communication base stations, but by expanding transmission bandwidth, just like widening highways.
In the 4G era, the frequency bandwidth has been greatly improved, and users feel that the network speed is faster, but the radiation standard of the 4G communication base station has not changed, and it is still less than 40 microwatts / square centimeter. The same is true of future 5G communication base stations. Moreover, the denser the coverage of the communication base station, the better the mobile phone signal reception, and the smaller the electromagnetic radiation the user will receive. Therefore, with the continuous construction of 4G and 5G networks, there are more and more communication base stations, better signals, and smaller radiation.
