In the application of the project, is the transmit power of wifi hotspot the bigger the better?

The bigger of the transmit power the easier to interference with other WiFi signals:

①Interference with the same frequency: will cause the bridge to search for multiple hotspots of the same channel, resulting in frequency distortion;

②Superimposed interference: the interference caused by the overlap of the hot signal will also cause frequency distortion;

③Intensity interference: the hot signal is too strong will also cause other signal transmission amplitude distortion, the principle of its interference as the big waves will cover the same small waves;

So the transmit power of wifi hotspot is not the bigger the better.
