If you check out the links, they'll go into teardowns of the lights and other electronics which have this 5G. I have a few things to say to "lighten" the concern. Note that the power supply of these transmitters isn't really so high, however the frequencies of these waves are in a similar range of microwaves which attenuate water molecules to 2-3 inches deep. Also note that these waves are not directed, but if they were they could be quite lethal. The symptoms they mention in the video are real but it varies from person to person. Also note that (and this is in Canada) I know someone who has a job of installing these transmitters and he told me they also have cameras inside each one for mass video surveillance. The cameras are small, like what you see in a webcam in size and they don't publicly document this. I'm really not sure about all this, but they haven't done any long term studies so it's strange who fast they're pushing it.
