China's communication base station standards strictly meet the requirements of national standards, with electric field intensity far less than 12 V/m and power density far less than 40 MW/cm2. In the mobile communication frequency band (800MHz-2 100MHz), China's electromagnetic radiation standard is stricter than the recommended standard of international non-ionizing radiation standard 1 1.25-26. However, the three major domestic operators are all verified and implemented according to this standard, so there is no difference in the radiation control of signal base stations.
When using a mobile phone, the radiation mainly depends on the mobile phone. The higher the power of the mobile phone, the greater the radiation. Therefore, if you want to reduce the harm of radiation when using a mobile phone, or choose a professional brand mobile phone, don't choose to use a small workshop mobile phone like a cottage, because the signal power control of such mobile phones is still not as good as that of brand mobile phones.
