5G network speed is so fast, the radiation must be very large

The issue of base station radiation has been widely discussed since the beginning of 3G construction. In the media and news, we often see community residents protesting together to prevent operators from installing signal base stations on rooftops or in communities.

In the 5G era, the network speed will reach 10Gb/s, which is several times that of 3G and 4G. Will it cause greater radiation to the human body?

How close is the base station?

If you want to know how much radiation base stations emit to the human body, you must first find out where these base stations are.

The setting distance of the base station is completely based on a formula in high school physics c = λν. The speed of light c is a fixed value. In order to increase the network speed, a higher frequency v must be used to transmit more data. A high frequency will cause the wavelength λ to become shorter, so the signal transmission distance will be shorter.

Therefore, the coverage distance of 2G base stations is about 10 kilometers, 3G is about 5 kilometers, 4G is only 3 kilometers, and 5G is only about 500 meters.

However, in actual operation, the terrain is complex and varied. Mountains, hills, ponds, reservoirs, high-rise buildings, bridges, etc. will affect the transmission of signals. In order to provide users with a good Internet experience, operators will carry out high-density laying.

As the world's first 5G city, Shenzhen has installed more than 46,000 5G base station towers on less than 2,000 square kilometers of land, an average of one for every 0.04 square kilometers. A more careful calculation means there is a 5G base station every 200 meters or so.

The district with the highest base station density in Shenzhen is Futian District, where 5,260 5G base stations have been installed in an area of ​​78.66 square kilometers, an average of one 5G base station per 0.01 square kilometers, or one 5G base station every 100 meters.

The 5G coverage construction across the country also maintains a base station density similar to that in Shenzhen. If you live in Shenzhen or in an area covered by 5G, you will definitely find the "square box" of the 5G base station if you observe carefully.

How much radiation does the base station radiate?

This "neighbor" with special skills is a "model worker" who works 24 hours a day. Does the radiation it produces have any effect on the human body?

In fact, not only mobile phone signals, but many objects in life will generate electromagnetic radiation, such as TV and computer screens, heating functions of microwave ovens and induction cookers, and sunlight is also a kind of radiation. The earth itself is a large magnetic field. We live in tens of thousands of different radiations at all times.

According to national standards, the electromagnetic radiation of communication base stations must be less than 40 microwatts/square centimeter. In actual implementation, operators will control each base station within 8 microwatts/square centimeter taking signal superposition into consideration.

The radiation from a hair dryer is about 100 microwatts per square centimeter, and that from a computer or television is about 70 microwatts per square centimeter. Compared to these, the radiation from a base station is very small and poses little harm to the human body.

Is 5G signal covered where you are? Have you seen 5G base stations?
