We have the right to use any frequency ?
Uh no but as I know , there is a range for uh for this uh f for for uh for this stuff , for designing this circuit. We can we can we can tune our uh transmitter to work in this range , and for this range we don't need to ask any permission.
Okay. And what happen with uh radio waves when two neighbours have the same  have our remote control , for example ? And so do they have the same frequency , or ?
Uh for this I'm not uh I I don't know the solution , but one solution can be something like putting uh p password or something inside the wave , so the only your T_V_ can understand it
