Note Dr. Davis wrote a book called Disconnect which disappeared quickly.
In an update interview with Tucker Carlson on Fox News (Apr 4, 2022), Dr. Davis also states this could be vastly ameliorated in software by putting the phone to sleep when next to the body and putting routers to sleep when not used which would also save energy. She further described possible effects of 5G which operates at a higher frequency (see my presentations on frequency and attenuation) requiring far more towers (800,000 in US), closer to the ground (30 ft) effecting residences. She also described current proposed legislation that will allow the cell phone companies to erect 5g cell towers wherever they would like regardless of local resident objections.
