"Pulsed RF created by the AC/DC conversion performed by smart and digital meters’ Switch Mode Power Supply (SMPS), generates frequencies between 2-50 KHz, which fall squarely in the range identified by the FCC as problematic.52 The FCC noted that “[a]dverse neural stimulation effects…include acute effects such as perception of tingling, shock, pain, or altered behavior due to excitation of tissue in the body’s peripheral nervous system.” 34 FCC Rcd at 11743-11744, ¶122 n.328. These are the same symptoms suffered by the “customers” and by others who report adverse health effects from smart meters. 34 FCC Rcd at 11742-11744, ¶¶119-122."
