Federal Communications Commission Occupational Safety and Health
Administration National Telecommunications and Information Administration The
National Institutes of Health participates in some interagency working group
activities, as well. FDA shares regulatory responsibilities for wireless phones with
the Federal Communications Commission (FCC). All phones that are sold in the
United States must comply with FCC safety guidelines that limit RF exposure.
FCC relies on FDA and other health agencies for safety questions about wireless
phones. FCC also regulates the base stations that the wireless phone networks
rely upon. While these base stations operate at higher power than do the wireless
phones themselves, the RF exposures that people get from these base stations
are typically thousands of times lower than those they can get from wireless
phones. Base stations are thus not the subject of the safety questions discussed
in this document.
• What kinds of phones are the subject of this update? The term wireless phone
refers here to hand-held wireless phones with built-in antennas, often called cell
mobile or PCS phones. These types of wireless phones can expose the user to
measurable radiofrequency energy (RF) because of the short distance between
the phone and the user's head. These RF exposures are limited by Federal
Communications Commission safety guidelines that were developed with the
advice of FDA and other federal health and safety agencies. When the phone is
located at greater distances from the user, the exposure to RF is drastically lower
because a person's RF exposure decreases rapidly with increasing distance from
the source. The so-called cordless phones; which have a base unit connected to
the telephone wiring in a house, typically operate at far lower power levels, and
thus produce RF exposures far below the FCC safety limits.
