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 dBi so Ant numeric gain= 1 Field strength = 57.64dBμV/m @3m @27.145MHz So Pt={ [10 (57.64/ 20) /10 6 x3] 2 /30}x1000 mW = 0.0005mW < 39 mW Then SAR evaluation is not required
