When do wifi jammers start to interfere?

Hello, I have experience with radio and bluetooth works with 2.4 Ghz. What does a jammer do to block the signal? WLAN and bluetooth also interfere with each other somehow, but how do you manage to completely block the signal, what's going on there? Is it enough to transmit with enough power?

Hello Paul,

You can imagine such a signal jammer as follows:

You and your interlocutor face each other at a distance that you can communicate with each other. But now someone with a megaphone is added to the bill, who is also within your reach and just keeps shouting into the megaphone. You can only communicate very poorly or no longer with your partner.

A jammer works the same way. By sending on the same frequency with a significantly stronger signal, communication between the network components is no longer possible or only possible with great difficulty.
