Trump was enthusiastic about implementing 5g because it works in the same/near the frequency range of WiFi(notice how similar 5G antennas are to WiFi antennas), which means that in an emergency all wi-fi can be used to bolster cellular networks with a firm/soft-ware upgrade.

5g isn't some magical super weapon, it is subject to the laws of physics just like everything else.

It's all a frequency VS wattage equation, as frequency goes up it is more readily stopped/absorbed by anything it passes through meaning it takes less power/wattage to cause a physical effect in the same way that a microwave cooks food, microwaves use much lower frequencies and need a correspondingly MUCH higher wattage to work the way they do.

(incidentally this also makes 5g much easier to shield from...)

The problem with 5g was and is that the wattage needed to cause physical effects is so much lower than with 4G, due to the higher frequencies the 5G hardware capable of putting out this wattage are a lot easier to hide than the equipment needed to put out the wattage needed for 4G to have a physical effect.

With 4G the parts would have been so much larger as to be very noticeable as wattage capability is very much reflected in the size of the components so physical harm sized components would have been impossible to hide from installers of the tech, and there are enough of them to make for a variable that was impossible to control/suppress, which is NOT the case with components sized for 5G frequencies.

That said, with wattages appropriate for communications usage in a cellular network 5G isn't any more problematic than 4G, put enough power through either and you will have harmful physical effects, the hardware needed to to do that with 5G is just a lot easier to hide....

The frequency range and physically shorter waves of 5G does however make it more usable for sending signals to micro or nano sized devices as the surface area of the receiving antenna can be a lot smaller...
