Question

Electronics

There is a question in passing the residence permit exam, in fact, the question arises, do they have devices that jam the connection and how to get around it? if I have a nano-capsule wireless earphone that picks up a signal from bluetooth, will the GSM jammer intercept its signal and block it? or GSM jammer blocks only cellular signals?

Answer 1

Silencers are different. The principle of operation for all is the same to create interference at a certain frequency range. Those. they do not pick up any signal. Of course, the wider the range and the further the range, the greater the power.
Theoretically, it is possible to bypass the jammer, practically impossible.

Answer 2

Pick up a hidden Wifi point not far from you.
