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 device. power
level in 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
