The principle and harm of mobile phone radiation

Transmission and reception of electromagnetic waves

Mobile phones send text messages and make phone calls by sending electromagnetic waves directly to the base station. When a mobile phone makes a call, the voice of the other party is provided to the mobile phone by electromagnetic waves emitted by the base station, so the radiation of the mobile phone can definitely reach the base station.

Signal strength evaluation

The signal strength mark on the mobile phone is given by evaluating the signal strength received from the base station.

Communication between mobile phone and base station

There is a lot of communication between mobile phones and base stations. The transmitting power of mobile phone is not constant. The mobile phone sends signals to the base station, and the base station keeps sending signals to the mobile phone.

Harm of mobile phone radiation

Cell phone radiation can cause some harm to human body, such as headache, insomnia, memory loss and so on. Therefore, attention should be paid to reducing the influence of radiation on the body when using mobile phones.
