Thanks for your recommendations. I tried your simple foil approach, and it measurably helped reduce the signal in the room - maybe a 50% reduction. And that's only with maybe 60% window coverage. I did not ground the foil or use foil on the walls - the walls are cement, frames are metal, and my hope is that the entire building (its a lar…
Thanks for your recommendations. I tried your simple foil approach, and it measurably helped reduce the signal in the room - maybe a 50% reduction. And that's only with maybe 60% window coverage. I did not ground the foil or use foil on the walls - the walls are cement, frames are metal, and my hope is that the entire building (its a large building) is grounded. My conclusion: shielding is an approach worth trying.
Something cheap like Chicken-fence may work for windows. Looks ugly though, but you can test how it works. You can later replace it with a (more expensive) fine metal grid that looks like a mosquito net/fence.
Note that the wave-length of the 5G can be very small. Your grid must be 50% smaller than the wavelength. With a <5 GHz transmitter the wavelength is >6 cm. So your fence should be like 3cm. But for short-distance transmissions 5G stations may also use much higher frequencies of 24–71 GHz (4 and 12 mm). Which is smaller than chicken-fence.
If you know what the source of the microwaves is, what frequencies are used, you can match your protection to it. You can also quick-test the protection by putting the metal grid around the meter. Or around your 5G telephone.
