The highest adjusted whole-body average SAR value from these simulations is 0.019 W/kg. This value
is below the US FCC whole-body SAR limits for both controlled (occupational) and general public
exposure environments, 0.4 W/kg and 0.08 W/kg, respectively.

The maximum measured gain of the antenna is used in this assessment to produce the conservative
evaluation of exposure in the operating condition of the radio.

The compliance relative to the US FCC limits for the peak 1-g average SAR [11] is evaluated at p=40
cm from the antenna by estimating an upper bound for said quantity. Evaluation of the peak power
density at 40 cm distance is performed based on maxim radiated power P =10 W and maximum
antenna gain G

 = 4.1 dBi:

Making the further conservative assumption that, at the point of maximum exposure, the whole
impinging power over a cross-section equal to one face of a 1-g cube of tissue (an area equal to 1cm

2

assuming that the tissue density is 1g/cm

3

) is absorbed by the body inside that cube, the following

upper bound for the peak 1-g average SAR is derived.

This value is below the US FCC peak 1-g average SAR limits [11] for both controlled (occupational)
and uncontrolled (general public) environments, 8 W/kg and 1.6 W/kg, respectively.
