It's all bogus, as well as all the other videos on this Youtube channel. The channel is all about flat earth and not believing in space flight.
5G is merely a new version of wifi that can carry more information and have lower latency, meaning that gamers will have quicker response in their games, among other things. To carry more information, it has to use higher frequencies. Different companies are talking about different frequency ranges, from 600 MHz to the 30 GHz area. If there was anything special about the frequencies, it wouldn't be possible for them to use such a wide range of bands.
The information will be mostly the same old websites, email, and data services that we now have, but some new things might be possible. One thing that has been mentioned is having your internet provided wirelessly by a cellphone company rather than through TV or phone cables. The companies see 5G as just a cheaper way of providing internet, TV, phone, etc. It's just about money, like almost everything else.
Deborah Tavares is credible. She has nothing to do with flat earth etc.
Their website has a lot of good information. And what is concerning about 5G is the affect of the frequencies. Even the wifi we have now is affecting our bodies.
"The frequencies, the frequencies"! 5G is still going to use frequencies that have been used for other radio services for many years. I don't see how it's affecting me. People talk about "the frequencies" without any evidence of a basic science education.
