                                      RF Exposure evaluation



According to 447498 D01 General RF Exposure Guidance v05

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 calculation

 The result is rounded to one decimal place for comparison



Worse case is as below: [2441 MHz -1.448dBm(0.7165mW)output power]



(0.7165 mW /5mm) ·[√2.441(GHz)]= 0.225 <3.0 for 1-g SAR



Then SAR evaluation is not required
