Will 5G base stations emit more radiation than 4G base stations? I finally figured it out

Despite repeated popularization of knowledge, many people still have misunderstandings about base stations, and many communities have experienced the farce of dismantling base stations and being unable to make or receive calls.

So how much radiation does a base station emit? Recently, at the 5G High-end Dialogue Forum of the Big Data Expo hosted by China Unicom, Wu Hequan, an academician of the Chinese Academy of Engineering, said, "Many people mistakenly believe that base stations are dangerous for electromagnetic radiation. The radiation standard for 4G base stations in the United States is 600 microwatts per square centimeter, while China's electromagnetic radiation standard is only 40 microwatts, which is 10 times stricter than that of the United States."

In fact, the radiation from a communication base station is not as strong as that from a room full of home appliances. At 10 meters from the base station, the radiation is only 1.5 microwatts, while the radiation from a microwave oven at home is 168 microwatts. At the same time, because the radiation coverage area of ​​the communication base station antenna is relatively wide, the radiation power is dispersed over an area of ​​several square kilometers, and the distance from the human body is often more than 10 meters, so the impact on the human body is relatively small.

At the same time, being close to a base station does not necessarily mean that the radiation is large. The electromagnetic waves of the base station are mainly emitted in the horizontal direction and are significantly weakened in the vertical direction, so the power density is often the smallest directly below the base station.

So will 5G base stations radiate more than 4G base stations? Wu Hequan also gave a negative answer: "The radius of 5G base stations is smaller than that of 4G, and the power is lower."

5G network is faster than 4G, not by increasing the signal transmission power of communication base stations, but by expanding the transmission bandwidth. 5G base stations are less than 40 microwatts per square centimeter, just like 4G base stations. Moreover, the denser the base station coverage, the better the mobile phone signal reception, and the less electromagnetic radiation users will be exposed to. Therefore, as more and more communication base stations are built, the signal will be better and the radiation will be smaller.
