Does the Unicom base station built in the community have an impact on the health of residents?

Hello, the maximum signal transmission power of the base station is 20 watts, and the transmission frequency is 900 MHz (or 1800 MHz), which is generally in the order of milliwatts when reaching the human body; But they are all within the scope of national safety standards and will not have any adverse effects on the human body. The transmission towers of communication facilities are approved by the local environmental protection bureau and are basically harmless.
