> Current cellphones represent a fourth generation, known as 4G, and 5G phones are expected to debut around 2020. They employ much higher frequencies, and these radio waves are far less successful at penetrating the bodies of humans and rats, scientists say. I'm confused by this statement. 4G uses even lower frequencies than 900 MHz, and this range up to 1900MHz will continue to be used for decades more, 5G or not. As for 5G itself, as I mentioned in another comment, there's also the issue of carriers needing to install many more towers, which I believe are cancer-causing for anyone living in the immediate area due to the power they radiate. I also imagine the 5G towers will use much more power than say 3G or 4G powers because if 5G wireless tech can't pass easily through objects, then you bet the carriers are going to "maximize" the distance. How? Through more power. So I doubt 5G will be much safer overall. In fact, I'm willing to bet it will be significantly less safe than previous wireless technologies. So to ensure companies like Qualcomm and U.S. carriers don't get away with causing millions to die "because we found out too late", like this NYT article seems to be implying about the previous tech, we should already start enforcing laws or starting lawsuits against them and make them pay out billions, if evidence is indeed found (whether through more studies, or through discovery of what the company employees knew about these issues) that their tech was harmful to humans.
