1 year agoAt the radio level much is very similar comparing 4G and 5G. So the radiation exposure, etc is mostly the same. Lots of studies show that below 6GHz has no known health impacts.
Above 6Ghz the scientific status is: probably no problem, but there still is a lack of longer studies, so it is easier to attack and researchers are hesitant to call it safe.
5G differs from 4G in many little details that extend the flexibility of the system. A main paradigm change is the extension to machine communication. 5G no longer only focuses on human communication, but also provides services for industrial communication or large sensor networks.
If available for your plattform of choice the older “Army of two” titles were quite nice.
