and thorough evaluation of scientific studies. The standards include a
substantial safety margin designed to assure the safety of all persons,
regardless of age and health.
The exposure standard for wireless mobile phones employs a unit of
measurement known as the Specific Absorption Rate, or SAR. The SAR limit
set by the FCC is 1.6 W/kg. Tests for SAR are conducted using standard
operating positions specified by the FCC with the phone transmitting at its
highest certified power level in all tested frequency bands. Although SAR
is determined at the highest certified power level, the actual SAR level of
the phone while operating can be well below the maximum value. Because
the phone is designed to operate at multiple power levels to use only the
power required to reach the network, in general, the closer you are to a
wireless base station antenna, the lower the power output.
Before a phone model is available for sale to the public, it must be tested
and certified to the FCC that it does not exceed the limit established by
the government-adopted requirement for safe exposure. The tests are
performed in positions and locations (e.g., at the ear and worn on the body)
as required by the FCC for each model.
The highest SAR values are:
* Head: 1.13 W/kg
* Body (Body-worn/Hotspot): 1.26 W/kg
(Body measurements differ among phone models, depending upon available
accessories and FCC requirements).
