Research on electromagnetic radiation from utility smart meters using RF communication.
Smart meters are digital utility devices that automatically transmit your energy usage data to power companies using radiofrequency (RF) electromagnetic fields in the 900 MHz to 2.4 GHz range. Unlike the old analog meters that required manual readings, these devices communicate wirelessly multiple times per day, creating a new source of EMF exposure directly on your home.
