I actually read the article as I'm unsure this is about safe-for-human-body or safe-for-network-security. What about the cell-phone-radiation-for-brain-cancer concern? Haven't heard about it for a while. 5G will work better in populated cities and I don't think it is a good fit for most areas in USA. Likely we will have 5G for very dense areas while 4G for the rest. I will absolutely not live or work in close vicinity of any 5G towers.
