Citizens’ groups and a handful of scientists have expressed concern that the radio frequency (RF) energy transmitted by 5G base stations may pose health risks. The FCC has been working on rules to protect wireless users from harmful RF emissions since 2015. The two key areas of concern are: The use of thousands of small transmission cells and the potential lack of control over their installation; and, the use of signals in the millimetre waveband, which are much higher frequencies than those used by existing telecom technology.
Citizens’ groups and a handful of scientists have expressed concern that the radio frequency (RF) energy transmitted by 5G base stations may pose health risks. While health authorities have shown little concern, they're seeking more research, according to Kenneth Foster, Professor of Bioengineering at the University of Pennsylvania.
