What is FDA’s role concerning the safety of wireless 
phones?
Under the law, FDA does not review the safety of radiation-emitting 
consumer products such as wireless phones before they can be sold, 
as it does with new drugs or medical devices. However, the agency 
has authority to take action if wireless phones are shown to emit 
radiofrequency energy (RF) at a level that is hazardous to the user. In 
such a case, FDA could require the manufacturers of wireless phones 
to notify users of the...

Safety
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...

brain cancer, glioma, meningioma, or acoustic neuroma, tumors of 
the brain or salivary gland, leukemia, or other cancers. None of the 
studies demonstrated the existence of any harmful health effects 
from wireless phone RF exposures. However, none of the studies 
can answer questions about long-term exposures, since the average 
period of phone use in these studies was around three years.
What research is needed to decide whether RF 
exposure from wireless phones poses a health 
risk?

FDA has been a leading participant in the World Health Organization 
International Electromagnetic Fields (EMF) Project since its 
inception in 1996. An influential result of this work has been the 
development of a detailed agenda of research needs that has driven 
the establishment of new research programs around the world. 
The Project has also helped develop a series of public information 
documents on EMF issues.
FDA and the Cellular Telecommunications & Internet Association 
(CTIA) have...

connected to a remote antenna. 
Again, the scientific data do not demonstrate that wireless phones 
are harmful. But if you are concerned about the RF exposure from 
these products, you can use measures like those described above to 
reduce your RF exposure from wireless phone use.
What about children using wireless phones?
The scientific evidence does not show a danger to users of wireless 
phones, including children and...

On the other hand, if the phone is mounted against the waist or other 
part of the body during use, then that part of the body will absorb 
more RF energy. Wireless phones marketed in the U.S. are required to 
meet safety requirements regardless of whether they are used against 
the head or against the body. Either configuration should result in 
compliance with the safety limit.
Do wireless phone accessories that claim to shield 
the head from RF radiation work?

This test method is now part of a standard sponsored by the 
Association for the Advancement of Medical Instrumentation (A AMI). 
The final draft, a joint effort by FDA, medical device manufacturers, 
and many other groups, was completed in late 2000. This standard 
will allow manufacturers to ensure that cardiac pacemakers and 
defibrillators are safe from wireless phone EMI.
FDA has tested hearing aids for interference from handheld wireless 
phones and helped develop a voluntary standard...

FCC Enhanced 911 (E911) Rules
Background
The Federal Communications Commission (FCC) requires wireless 
carriers to transmit specific latitude and longitude location (Automatic 
Location Identification = ALI) information as well as “911” calls to 
Public Safety Answering Points (PSAPs) to identify the location of 
the caller in case of emergency. Generally, the rules require that 
carriers...
