MM-waves used for 5C also work via VGCC activation. 5C is designed to carry extraordinarily high amounts of information per second and is, therefore, extraordinarily highly pulsed. The electrical parts of these MM-waves do not penetrate well into buildings, such that millions of 5C antennae are planned in close proximity to our home, schools, churches, businesses, etc, such that it will be nearly impossible to avoid exposures. Given the high pulsation level for 5C radiation, even short exposures may well produce severe biological effects. In addition to this, the finding that 5C systems involve output power sometimes like 30 times higher output than did previous systems, we have an strong argument for disaster (Human exposure to RF fields in 5G downlinI Nasim, S Kim - arXiv preprintarXiv:1711.03683, 2017 - arxiv.org)
