3. What kinds of devices are the subject of this update?
Theterm“wirelessdevice”refershereto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RadioFrequency(RF)energybecauseof
theshortdistance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theuser,theexposuretoRFisdrasticallylower
becauseaperson’sRFexposuredecreasesrapidlywithincreasingdistancefromthe
