Yes, the aluminum foil to prevent mobile phone signal, stop the normal use of mobile phones, in our school, our teacher will give us such an experiment, the phone encase with aluminum foil and then make a phone call. Since then, we've known that aluminum foil is the equivalent of using a cellphone jammer to block the signal. If you don't want to get a phone call, you can wrap your cell phone in aluminum foil without being harassed by the phone.

Tin foil and aluminum foil can block/shield electromagnetic signals, which can be shielded, regardless of frequency, M, G, or higher. It is harmless to human body and can be used safely. Aluminum foil of course can, as long as it is metal, wireless electromagnetic signal cannot be through metal or metal mesh. In general, electrically conductive metals can reflect radio signals, shielding the target completely. The more practical material is aluminum foil, one layer can not pack several layers.

With iron box, but also need grounding, shielding principle of it is to put the electromagnetic waves received by tin box first, and then import the underground, but the effect is not particularly good, everyone can be found by train, or full of the signal, only through the tunnel, the signal completely interrupted. So, when you're not using a screening device, look for a room with no Windows or Windows, doors or iron, and if the walls are reinforced concrete, you can block it. Or is to find a box, lined with lead plate, need not grounding, absolute silence, this kind of box is lead layer thickness is used to the radioactive material, so its shielding effect as you can imagine.

The foil paper is not used to transmit signals in order to block the interference of the outside and the interference of the external to the transmission signal. There will be some shielding, but you can't completely block the phone signal.See related articles on the Internet before said the aluminum foil can block cell phone signals, I feel very magical, so I just want to try in person, I have purchased aluminum paper, mobile phone package firmly, and then I use another phone call by the phone, and then prompt voice is "you dialed temporarily unable to get through the number", that means that the aluminum foil can be shielded cell signal, this is what reason is caused? So I started to look for the reasons online.
