The exposure standard for mobile devices employs a unit of
measurement known as the Specific Absorption Rate, or SAR.
The SAR limit stated in the international guidelines is
2.0 watts/kilogram (W/kg) *. Tests for SAR are conducted using
standard operating positions with the device transmitting at its
highest certified well below the maximum value. This is because
the device is designed to operate at multiple power levels so as
to use only the power required to reach the network. In general,
the closer you are to a base station, the lower the power output
of the devicein all tested frequency bands.
Although the SAR is determined at the highest certified power
level, the actual SAR of the device while operating can be well
below the maximum value. This is because the device is
designed to operate at multiple power levels so as to use only
the power required to reach the network. In general, the closer
you are to a base station, the lower the power output of the
device.
SAR values may vary depending on national reporting and testing
requirements and the network band. Use of device accessories
and enhancements may result in different SAR values.
The SAR limit for mobile devices used by the public is 2.0 W/kg
averaged over 10 grams of body tissue. The guidelines
incorporate a substantial margin of safety to give additional
protection for the public and to account for any variations in
measurements. SAR values may vary depending on national
