Actually, it goes way beyond this. Consider chemtrails. They are made up of, among other things, nano aluminum oxide and some form of nano barium. These and others have been sprayed throughout the air of America (the world?) in large quantities for the last 12 years, and they have been sprayed to some extent since the 1950s.
Where do these nano metals/minerals go after they have been sprayed into the air? Everywhere. Into our lungs through the air we breathe. Onto and into the ground as the rain washes them out of the skies. Into the food that grows in the ground, and later into our bodies when we eat this food. Much of it ultimately goes into our brains in nano form.
What does it do in our brains? Much of it simply sits there. Some of it causes all kinds of diseases of the brain (and body), especially in people who have compromised immune systems, and in others who are simply genetically weak in some specific area that these particles can attack.
But what is the real purpose why the elite might want it in our brains? And what does this have to do with 5G and smart meters? Here's what. Both aluminum and barium are materials that are easily affected by radio waves. Both of them aren't easily dissolved in the body and converted into other body chemicals - meaning that they just sit there, in the body, until the body can wash them out through natural cleansings.
This means that the 5G radio controllers can affect the way we think by focusing 5G radio waves, tuned by smart meters for particular localities, on our brain-filled, electronically-reactive metals/minerals. We can be controlled like unsuspecting zombies.
The simplest result will be many deaths... to help depopulate the world as the elite want. A second result will be to change the common-sense mentality of many Americans so that American freedom - particularly gun freedom - will be brought into slavery. But ultimately it will be used to bind the peoples of the world into a one-world government, by actually changing their socialistic fears and desires.
All of this will be used to put down the religious belief in God, and especially the belief in the Savior, Jesus. When there are only a few Jesus believers left in the world, and they are in danger of being lost, then Jesus will return to help them fight the elite enemy.
Some of the technology is already available to start this zombie control right now. Other of it is being developed... and it includes the AI that will be needed to do the actual complex coordinating of the controlling.
The simple Faraday cage is not capable of protecting from 5G and smart meters, especially with our chemtrail-compromised brains. For protection, we will need houses surrounded in metal sheathing. And they will have to be set up in ways so that we don't use any of our electronic devices within, or the waves from these devices will fry us.
Strategic thinking will have to go into the ways we make and protect our housing. Start to think by activating your smartphone, and then sticking it into an unplugged microwave oven. Look at the face of it through the window once you close the oven door. Watch how it loses network connectivity as the connectivity bars go down. This will give you ideas about how to protect yourself using metal screens.
Just think of it. After a while you will probably see a bunch of us enlightened jokers walking down the streets with microwave ovens around our heads.
