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 So pt = (EXd) 2 /30 x gt Ant gain =2.1dBi so Ant numeric gain= 1.62 Field strength =86.35dBμV/m @3m@2402MHz So Pt={ [10 (8 6.35/20) /10 6 x3] 2 /(30)}x1000 mW = 0.13 mW <2.79 mW Then SAR evaluation is not required
