The exposure standard for wireless mobile USB Modems employs a unit of measurement
known as the Specific Absorption Rate, or SAR. The SAR limit set by the FCC is 1.6W/kg.
*Tests for SAR are conducted using standard operating positions accepted by the FCC with
the USB Modem transmitting at its highest certified power level in all tested frequency bands.
Although the SAR is determined at the highest certified power level, the actual SAR level of
the USB Modem while operating can be well below the maximum value. This is because
the USB Modem is designed to operate at multiple power levels so as to use only the poser
required to reach the network. In general, the closer you are to a wireless base station
antenna, the lower the power output.
The highest SAR value for the model USB Modem as reported to the FCC is
1.02
W/kg
(Body-worn measurements differ among USB Modem models, depending upon available
enhancements and FCC requirements.)
While there may be differences between the SAR levels of various USB Modems and at
various positions, they all meet the government requirement.
