one of the major reasons that so called mm-wave is far safer than previous low/ mid-band (i.e. < 6GHz) technologies is the following.mm-wave frequencies (e.g. 28Ghz) allow the use of array antennas (i.e. Phased Array Antennas, PAA's).
The reason this is so much safer is because the PAA's produce "pencil width beams" that is, the beams are very narrow. Rather than blasting away in all directions like the sub-6Ghz bands, the beam is focused on the PAA antenna. Why is this safer?
because, if something, like, let's say a human, comes in between the transmitter and the receiver, the signal will be completely lost. Hence, at this point the PAA controller will stop transmitting or scanning in that direction. So there is no radiation in that direction.
So, if you are worried about it, just turn off mm-wave capability (e.g. turn off 5G UWB). But honestly, you don't have to worry, the beam (and energy) is very focused, if anything comes in the way, even a wet piece of paper, or a person, it stops. This means that mm-wave is far safer than previous 4G in the mid to low bands. 5G in the mid to low bands are basically the same as 4G but have a much more efficient use of the spectrum.
So overall, 5G is faster, lower latency and safer than 4G or 3G or anything that came before.
Of course there is a lot of misinformation from various propaganda sources that want to confuse the public.
- sschueller 7y agoWe cannot rely on devices always cutting communication when something goes in between. Do you trust all Chinese manufacturers to correctly implement such features? If 5g was a 5mW laser beam that would cut out on interference, would you trust it always working? Mm waves may not be harmful to humans but there are some studies that show retinal damage in mice at certain frequencies. Until at least some studies on humans have been done we should not all jump into this like nothing can go wrong and it's guaranteed safe because communication is cut automatically on interference.
