5    SAR Evaluation
5.1 RF Exposure Compliance Requirement
5.1.1 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.
5.1.2 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

                                                                                             17
                                         unded to the nearest mW and mm before calculation

     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
5.1.3 EUT RF Exposure
                                 2
     eirp = pt x gt = (E x d) /30
     where:
     pt = transmitter output power in watts,
     gt = numeric gain of the transmitting antenna (unitless),
                                                  ((dBμV/m)/20)   6
     E = electric field strength in V/m, ---10                /10 ,
     d = measurement distance in meters (m)---3m,
                      2
     So pt = (E x d) /30 / gt


     The worst case (refer to report CQASZ20180500094E-01) is below:


     For 2.4G wireless:
     Field strength = 88.98dBμV/m @3m
     Ant. gain 1.3dBi; so Ant numeric gain=1.35
                (88.98/20)   6       2
     So pt={[10           /10 x3] /30 /1.35}x1000mW =0.176mW
     So (0.176mW/5mm)x √2.477GHz = 0.055,


     0.055<3.0 for 1-g SAR


     So the SAR report is not required.
