New technologies frequently spark public concern, and smart meters are no exception. One of the questions raised is whether radio frequenc (RF) signals in the 900 MHz region of the electromagnetic spectrum pose a threat to public health. The answer is, no.
Smart meters communicate intermittently via RF signals over short distances, so the energy of their radio waves is weak. Radio-wave energies put out by other wireless technologies—including radios, televisions, cell phones, and even nursery monitors—emit stronger RF signals than do smart meters. No public health agency has labeled smart meters as dangerous to our health.
