RF Exposure evaluation For FCC ID: 2BVHX-CD-0328A 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 =0dBi so Ant numeric gain= 1 Field strength =76.81dBμV/m @3m@315MHz So Pt={ [10 (76.81/20) /10 6 x3] 2 /(30x1)}x1000 mW = 0.0144mW <36.3185mW Then SAR evaluation is not required
