Even if I don't have a hammer handy, I could probably find something in the middle of the night to smash the thing. A Faraday cage on the other hand...
Do I need to turn on the microwave with the phone inside it? This is an honest question because I don't know anything about microwave signals (I could google/research), but my instinct tells me I probably shouldn't turn on the microwave with the phone inside it, though I don't know for sure what will happen (explode?)
I wonder if it shouldn't be a thing we keep handy. Like a foldable Faraday cage (bag ?) big enough to fit a laptop that can be whiped out in case of emergency.
They definitely make Faraday cage bags that are about as thick as heavy mil trash bags. Depending on the issue (EMP?) you may need to double bag if primitive YouTube experiments are anything to go by (basically, does the phone ring/radio receive once it's enclosed).
They did quite well for 3G and even 4G which didn't have as many above 2.4GHz , but after 4GLTE, 5G has added a lot of mid-bands between 2.6-6GHz. Those tend to leak more since they have shorter wavelengths than microwaves are built around 2.4GHz. Some of them are only used in a few countries, but n2 & n77 are widely used by ATT.
Usually. You can check by putting your phone in and closing the door while looking at the signal strength meter. It should go without saying don’t turn the microwave oven on with your expensive electronics inside. If you get decent reception in the closed oven, you need a new one.
Definitely works to kill reception forever if you power up the microwave for a couple of minutes…
No, they used it as acoustic insulation for the microphones and optical insulation for the cameras. The signal blocking, if any, is just a bonus, but isn't to be relied upon.
