>> However, we have considerable evidence about the harmful effects of 2G and 3G. Little is known the effects of exposure to 4G, a 10-year-old technology, because governments have been remiss in funding this research. What would be the difference between 2G/3G and 4G from a health perspective? Does 4g transmit on different frequencies or at a higher power level or something? My assumption was that they were pretty similar from a "radio" perspective, and the differences were mostly in the protocol.
