RF exposure evaluation
§2.1093 Radiofrequency radiation exposure evaluation: Portable Devices.
According to§15.247(i) and§1.1307b(1), systems operating under the provisions of this section
shall be operated in a manner that ensures that the public is not exposed to radio frequency
energy level in excess of the commission’s guidance.
The 1-g SAR test exclusion thresholds for 100 MHz to 6 GHz at test separation distances ≤ 50 mm are
determined by:
[(max. power of channel, including tune-up tolerance, mW) / (min. test separation distance,
mm)] · [√f(GHz)] ≤ 3.0 for 1-g SAR, where
•
f(GHz) is the RF channel transmit frequency in GHz
•
Power and distance are rounded to the nearest mW and mm before calculation
•
When the minimum test separation distance is < 5 mm, a distance of 5 mm according is applied
to determine SAR test exclusion.
•
The result is rounded to one decimal place for comparison
