Wireless networks transmit voice and data using radiofrequency energy. RF is a portion of the electromagnetic spectrum (which is comprised of waves of electric and magnetic energy moving together through space) in the “radio wave” range.
Radio frequency transmissions are generated by and used in many modern applications, including light bulbs, baby monitors, healthcare devices, home and industrial appliances, radios, satellites, TVs, radios and cell phones.
The FCC relies on research and recommendations from leading public and private experts to develop its RF exposure limits. Specifically, the FCC’s RF exposure limits are based on recommendations from the U.S. Environmental Protection Agency (EPA), the Food and Drug Administration (FDA), the National Institute for Occupational Safety and Health (NIOSH), Occupational Safety and Health Administration (OSHA), the National Council on Radiation Protection and Measurements (NCRP), the American National Standards Institute (ANSI) and the Institute of Electrical and Electronics Engineers, Inc. (IEEE).
In December 2019, after 6+ years of public input and review, the FCC reaffirmed its RF exposure standards, finding that evidence “does not demonstrate that the science underpinning the current RF exposure limits is outdated or insufficient to protect human safety.”
In addition to FCC regulation, respected independent national and global organizations — including the American Cancer Society, the World Health Organization, and the National Cancer Institute— agree that there are no known adverse health effects from cell sites that comply with FCC rules. Supported by scientific consensus, every single one of these expert institutions has adopted positions that substantiate the FCC’s conclusion: wireless communications facilities meeting current FCC RF exposure standards have no harmful effect on human health.
And, as recently as February 2020, the FDA’s Center for Devices & Radiological Health completed a review of over 10 years’ worth of RF exposure data, finding “the available epidemiological and cancer incidence data continues to support the [FDA’s] determination that there are no quantifiable adverse health effects in humans caused by exposures at or under the current cell phone exposure limits.”
“No obvious adverse effect of exposure to low level radiofrequency fields has been discovered.”
- The World Health Organization (WHO)
“No consistent evidence for an association between any source of non-ionizing EMF and cancer has been found.”
- National Cancer Institute (NCI)
“The incidence of brain tumors in human beings has been flat for the last 40 years. That is the absolute most important scientific fact.”
- American Cancer Society (ACS)
“If these waves were dangerous, we would have died from AM/FM radios, TVs, GPS, and garage door openers a long time ago.”
- American Council on Science and Health
“There is no evidence to support adverse health effects in humans caused by exposures at, under, or even in some cases above, the current RF limits.”
- U.S. Food & Drug Administration (FDA)
“At this time we do not have the science to link health problems to cell phone use”
- Centers for Disease Control (CDC)
“The possibility that a member of the general public could be exposed to RF levels in excess of the FCC guidelines is extremely remote.”
- Federal Communications Commission (FCC)
That is not true. The FCC RF exposure limits apply to all spectrum up to 100 GHz. In the foreseeable future, AT&T small cell facilities will operate at frequencies below 40 GHz and RF exposure to the general public at those facilities is as low as 200 times below the FCC limits.
Wireless carriers must follow FCC RF exposure limits. The FCC, based on input from respected science, engineering and health organizations, has concluded that all antennas that meet its RF exposure limits have no harmful effect. AT&T’s wireless facilities — including small cell deployments — are designed and operated to comply with these FCC exposure limits.
RF is emitted from devices all around us — from light bulbs and televisions, to stereos and baby monitors. Small cell antennas, like radios, Wi-Fi hotspots, wireless routers and the like, emit low levels of RF.
Small cell facilities are different than traditional cell towers. They operate at power levels lower than traditional cell towers. Because small cells help optimize the network, use of small cells also reduces the power and radio transmissions — including RF energy — mobile phones use to make calls and send data.
The FCC limits the amount of RF exposure that is allowed from all cell sites, including small cells. AT&T’s small cell sites will create general public exposure as low as 200 times below the FCC limits.
No. RF exposure guidelines are exclusively within the FCC’s authority. A Federal statute preempts cities and states from enacting their own regulations that conflict with the FCC’s, science-based RF exposure requirements. In its December 2019 Order, the FCC reaffirmed this preemption, stating “state-level warning regimes risk contributing to an erroneous public perception or otherwise disrupt the federal regime.”
Consistent with FCC requirements, AT&T will post notices on poles and wireless equipment where a utility worker could get close enough to an antenna to be exposed to higher levels of RF energy. These notices are not directed to the general public, as exposure at ground level, at a home, or in a publicly accessible area would be far (up to 200 times) below the FCC limits for harmful effects.
