RF Exposure evaluation According to 447498 D04 Interim General RF Exposure Guidance v01 eirp = pt x gt = (EXd) 2 /30 where: pt = transmitter output power in watts, gt = numeric gain of the transmitting antenna (unitless), E = electric field strength in V/m, --- 10 ((dBuV/m)/20) /10 6 d = measurement distance in meters (m)---3m Sopt = (EXd) 2 /30 x gt Ant gain = -0.3 dBi [-2.45dBd(0.57) ] Field strength = 85.39 dBμV/m @3m @5847MHz So Pt={ [10 (85.39 /20) /10 6 x3] 2 /（30x0.93）}x1000 mW =0.1116mW<2.781mW So ERP=0.1116x0.57=0.064<2.781mW Then SAR evaluation is not required
