What is the relationship between cell phone signal and radiation?

The better the signal, the less radiation. Why? Let me explain it to you.

Suppose you and your friends are 1 m away, and you can talk to each other very quietly.

If you are ten meters away, you must speak loudly.

At a distance of 1 m from the antenna, the cell phone signal is very good, so the cell phone can transmit information with low power consumption.

However, at the distance of 100 meters, the mobile phone has to emit powerful power to transmit to the antenna.

In addition, the mobile phone antenna is omni-directional, that is, it has no direction, so it is different from talking and bigger than talking. So the power will be high when the signal is bad.

In addition, there is another situation where the power will be very high, that is, when the mobile phone searches for the base station, the mobile phone does not know the distance from the base station and can only send information in all directions with high power. So when you send and receive text messages and incoming calls, the nearby stereo will be disturbed, which is high power. After this high-power period, the mobile phone can reduce its power by knowing where the base station is, so the stereo will be fine after you answer the phone.
