The FDA shares regulatory responsibilities for wireless
devices with the Federal Communications Commission
(FCC). All devices that are sold in the United States must
comply with FCC safety guidelines that limit RF exposure.
The FCC relies on the FDA and other health agencies for
safety questions about wireless devices.
The FCC also regulates the base stations that the wireless
device networks rely upon. While these base stations
operate at a higher power than wireless devices themselves,
the RF exposure on people from these base stations is
typically thousands of times lower than it is from wireless
devices. Base stations are thus not the subject of the safety
questions discussed in this document.
3. What kinds of devices are the subject of this update?
The term 'wireless device' refers here to handheld wireless
devices with built-in antennas, often called 'cell' , 'mobile' ,
or 'PCS' devices. These types of wireless devices can
expose the user to measurable radiofrequency energy (RF)
because of the short distance between the device and the
user's head. These RF exposures are limited by FCC safety
guidelines that were developed with the advice of the FDA
and other federal health and safety agencies. When the
device 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 devices, ' which have a
base unit connected to the device wiring in a house, typically
operate at far lower power levels, and thus produce RF
exposures far below the FCC safety limits.
4. What are the results of the research done already?
The research done thus far has produced conflicting
results, and many studies have suffered from flaws in
their research methods. Animal experiments investigating
the effects of radiofrequency energy (RF) from wireless
devices have yielded conflicting results that often cannot
be repeated in other laboratories. A few animal studies,
however, have suggested that low levels of RF could
accelerate the development of cancer in laboratory animals.
However, many of the studies that showed increased tumor
development used animals that had been genetically
