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 handheld wireless
phones with built-in antennas, often called “cell”, “mobile”, or
“PCS” phones. These types of wireless phones can expose the
user to measurable Radio Frequency (RF) energy because of the
short distance between the phone 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 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.

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 Radio
Frequency (RF) energy exposures characteristic of wireless
phones 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
