Raum Handyfrei abdichten?
Hallo!
Ich frage mich, ob es irgendeinen Weg gibt einen Raum so zu gestalten, dass die Benutzung eines Smartphones oder jeglicher anderer Bildschirme unmöglich wird.
In einem Bunker zB hat man ja keinen Empfang – auch hier würde mich interessieren, wie genau man einen Raum baut, der weder Empfang, noch WLAN Signal aus dem Nebenzimmer hindurchlässt.
Aber eben auch einen Schritt weiter: Sodass die Bildschirme beim Betreten nicht mehr funktionieren.
Wenn so etwas möglich ist – ist es gesundheitlich bedenklich, sich längere Zeit in einem solchen Raum aufzuhalten?
Freue mich auf eure Antworten, danke! 🙏🏻

This is quite feasible to shield a room like this, but this is not done with a metal grid or foil on the walls.
Try and put your phone in the microwave, which should be radiation-proof, and then call it. Spoiler: it rings!
In addition to welded metal plates on the walls, you still have to worry that no power cables or the like transfer the radio waves into the room.
And yes, a permanent shielding of any electric and magnetic fields is health-friendly.
In my thought experiment, I build a bedroom by prohibiting mobile phones – therefore, the interest in shielding signals and preferably screens to make mobile phone use as unattractive as possible.
Do you think this is safe for health? And if so, why?
Firstly, it would work only to a limited extent, because often enough waves come through the window pane and through slip holes such as sockets etc.
There was a study of apartments in reinforced concrete. This alone led to insensitivity disorders during a permanent stay, even if this is not enough to block the cell phone reception.
You can even buy disturbing transmitters with the indication that the use is prohibited throughout the EU.

If the bunker is correspondingly deep and massively built, there are no more signals.
In addition, signals can also be disturbed with interference devices, so-called jammers.
However, the operation of such devices is prohibited in Germany without the approval of the Federal Network Agency.
Could you build a room with windows in a condominium accordingly massively?
I listen to jammers for the serious time, thanks for the new knowledge!
It should be discussed with an architect. I’m no one myself.
Connecting metal nets to all walls, ceiling and floor, with one another and with water pipe
What role does the water supply play? Is this the construction of a Faraday cage from which the other comments speak?
The water line would be only a grounding, but it is not necessary for the cage
Exactly, and the metal cage must be earthed

I read myself, thank you.
Through a narrow-mesh color-day cage, you can shield the cell phone so that no more signal passes. However, you cannot disturb the basic function of the device without EMP and then it is also broken.
What is an EMP?
Electro Magnetic Impulses
The impulses destroy all unprotected circuits
An ElectroMagneticPulse, high-energy electrical radiation that can destroy circuits…
An EMP is an electromagnetic pulse, i.e. a type of wave that destroys any technical device in a specific circle during ignition.
And can such a cage be integrated into the walls?
yes, you can wall or plaster
Okay got it, thanks to all the answers!
You confuse EMP with an EMP bomb, with EMP itself nothing is ignited
you will not be able to paralyze the screens, but the radiation.
something similar to a Faraday cage could go.
because this is only a cage, this would be completely harmless to health.
You can block the signals, but screens (e.g. tablets) will continue to display.
Lots of concrete and a lot of steel.
Stick the entire room without gaps (also the windows) with aluminum foil.
