Every year, doorbells are gradually being improved, and the times when a dull and sometimes frightening sound was heard with the press of a button in the apartment are a thing of the past. Now the ringtone can be the most diverse - from the twitter of birds to some hit melody. Moreover, the progress has reached such an extent that you can use this tool without pulling any wires.

Only now it is fed not through wires, but through radio waves.
Where do they apply?
