Block cell phone cameras - tin foil block cell phone signal at home
That’s quite a popular question) When we use a Wi-Fi connection we operate the 2.4 GHz frequency. You know, lots of devices operate at the same frequencies, Bluetooth, for example. And a lot of devices can emit signals on that frequency while working. To answer that question you need to know how a signal jammer works.
It simply creates the white noise on the specified frequencies on the certain area so the signal that carries information is simply blocked by that noise. Microwave oven is the device that can interfere with 2.4 GHz frequency, but I doubt that it can jam the signal totally. The other minuses are that that you cannot adjust the output signal power and to make a strong interference you’ll have to put an oven near the signal source. I do not recommend to experiment with the microwave to jam the Wi-Fi. The best way to block a Wi-Fi is to use the device that jams the Wi-Fi.
Thanks for your question and I hope that helped!
