The National Institutes of Health participates in some 
interagency working group activities, as well. 
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. FCC relies on FDA and other health 
agencies for safety questions about wireless devices. 
FCC also regulates the base stations that the 
wireless device networks rely upon. While these base 
stations operate at higher power than do the wireless 
devices themselves, the RF exposures that people 
get from these base stations are typically thousands 
of times lower than those they can get from wireless 
devices. Base stations are thus not the primary 
subject of the safety questions discussed in this 
document.
