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 = 5 dBi Max Output power =-2.188dBm @ 2402MHz ERP = -2.188dBm+5dBi-2.15=0.662dBm So ERP is worse case 10^0.0662=1.165 mW < 3 mW Then SAR evaluation is not required
