FAQs: Wireless Communications and Advanced Meters 

    Our advanced meters (also known as smart meters) communicate using a low-power radio frequency (RF) signal. Radio frequency is another term for radio waves or wireless signals. This allows for the two-way wireless communication between Ameren and the meters through our next generation energy delivery system.
    Scientific research has been conducted on radio-frequency (RF) fields and health for several decades, and this body of research has been reviewed by many public health and regulatory agencies. None of these organizations have found that the RF signals from AMI meters cause or contribute to any adverse health effects. In addition, the Advanced Metering Infrastructure (AMI) meter transmits RF for only a few minutes each hour at an extremely low signal strength level comparable to other home devices such as cordless phones or wireless baby monitors.
    You probably have one or more commonly used household devices that transmit and receive data using radio frequency signals, including video game controllers, cell phones, televisions, computers, baby monitors, radios, security systems, garage door openers and Wi-Fi routers.
    The Food and Drug Administration (FDA), Federal Communications Commission (FCC), World Health Organization (WHO), American Cancer Society (ACS) and National Cancer Institute (NCI) consider AMI meters safe.
    The wireless signal from AMI meters is weaker than that of most common household wireless devices. If other wireless devices in your home do not interfere with your medical device, it is extremely unlikely that an AMI meter will interfere. However if you suspect interference, please let us know so we can investigate a solution. Also, the wireless signals from advanced meters comply with all Federal Communications Commission (FCC) regulations for commonly used consumer wireless devices.
