I’m kinda sold on it being detrimental if you’re there, but like I said, it’s diet coke for a 600 pounder. I wouldn’t be leaping to cram my house full of it, but aside from installing your surveillance internet router outside and running some cable indoors, there ain’t much the average person can do to mitigate their exposure unless they can operate like it’s 1990 and forego all these snazzy devices. 

It’s been a long time since I went to class and talked about this stuff, but from what I remember there are already higher powered signals in use.  TV signals have been bombarding us from embryonic development and those are like, twice as spicy as 5G. Hell, we just ad ADS-B broadcast from 2020 and beyond. Wonder how potent that is. I sure can pick it up a long ways out.
