What does Specific Absorption Rate (SAR) mean?
In 1996, the FCC, working with the FDA, the U.S.
Environmental Protection Agency (EPA) and other
agencies, established RF exposure safety guidelines for
wireless devices in the United States. Before a wireless
device model is available for sale to the public, it must
be tested by the manufacturer and certified to the FCC
that it does not exceed limits established by the FCC.
One of these limits is expressed as a Specific Absorption
Rate, or "SAR." SAR is a measure of the rate of absorption
of RF energy in the body. Tests for SAR are conducted
with the wireless device transmitting at its highest
power level in all tested frequency bands. Since
1996, the FCC has required that the SAR of handheld
wireless devices not exceed 1.6 watts per kilogram,
averaged over one gram of tissue. Although the SAR is
determined at the highest power level, the actual SAR
