A Faraday cage against electrosmog?

Shielding sounds logical but has side effects. Why a dead zone makes your phone transmit more strongly.

By Mike Fuhrmann, VIVOBASE Switzerland

A Faraday cage is a closed enclosure made of conductive material that lets hardly any electromagnetic waves through. You know the principle from everyday life: you are protected in a car during a thunderstorm, and in a lift your phone reception often drops.

Can you shield yourself from electrosmog this way?

In principle, yes. There are shielding paints, curtains, bed canopies and phone cases. In everyday life, however, this has limits: shielding only works if it has no gaps, and it also blocks the signals you actually want to use.

The catch: your phone transmits more strongly

If your phone has poor reception, it increases its transmission power to keep the connection. A case that partially blocks the signal can therefore cause the device to transmit more strongly than before. The Federal Office of Public Health also points this out: good reception reduces radiation.

In shortShielding can make sense in individual cases, for example in the bedroom. On the go it is usually impractical, and if done badly even counterproductive.

The simpler levers

  1. Distance instead of shielding. Even one metre makes a big difference.
  2. Switch off what you don't need. Wi-Fi off at night, airplane mode in the bedroom.
  3. Good reception. Make calls where the network is strong.

And VIVOBASE?

VIVOBASE is deliberately not a shield. It does not block any signals; your phone and Wi-Fi work as usual. Many people use it as a simple addition to the habits above.

Quick answers

Does a shielding phone case protect against radiation?

Not necessarily. If the case partially blocks the signal, the phone transmits more strongly to keep the connection. Distance and good reception are more effective.

Is VIVOBASE a shield?

No. VIVOBASE does not block any signals. Phone, Wi-Fi and 5G work as usual.
