Doesn't help that the article is written in a kind of exaggerated, fear mongering way. E.g.:
"
5G also employs new technologies (e.g., active antennas capable of beam-forming; phased arrays; massive inputs and outputs, known as MIMO)
"
MIMO is multiple inputs, multiple outputs, not massive. If the author is bending terminology to enhance his case, that makes the case look weaker...
Yeah. If an average person thinks MIMO stands for Massive Inputs and Outputs that's not a bad mistake. If someone purporting to speak with authority on the subject of RF radiation thinks that, it's grounds to suspect them of being a blithering fool.
