SAR Evaluation
4.1 RF Exposure Compliance Requirement
4.1.1 Standard Requirement
According to KDB447498D01 General RF Exposure Guidance v06
4.3.1. Standalone SAR test exclusion considerations
Unless specifically required by the published RF exposure KDB procedures, standalone 1-g head
or body and 10-g extremity SAR evaluation for general population exposure conditions, by measurement
or numerical simulation, is not required when the corresponding SAR Exclusion Threshold condition,
listed below, is satisfied.
4.1.2 Limits
The 1-g and 10-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 and ≤ 7.5 for 10-g extremity SAR, where
 f(GHz) is the RF channel transmit frequency in GHz
 Power and distance are rounded to the nearest mW and mm before calculation17
 The result is rounded to one decimal place for comparison
The test exclusions are applicable only when the minimum test separation distance is ≤ 50 mm and
for transmission frequencies between 100 MHz and 6 GHz. When the minimum test separation
distance is < 5 mm, a distance of 5 mm is applied to determine SAR test exclusion

The Max Conducted Peak Output Power is -0.210dBm in lowest channel(2.402GHz);
The best case gain of the antenna is 0dBi.
EIRP= -0.210dBm + 0dBi = -0.210dBm
-0.210dBm logarithmic terms convert to numeric result is nearly 0.953mW
According to the formula. calculate the EIRP test result:
[(max. power of channel, including tune-up tolerance, mW)/(min. test separation distance, mm)] ·
[√f(GHz)]
General RF Exposure = (0.953mW / 5 mm ) x √2.402GHz = 0.295 ①
SAR requirement:
②;
S= 3.0
① < ②.
So the SAR report is not required.
Remark: The Max Conducted Peak Output Power data refer to report Report No.: CQASZ20180700073E-01
