RF Exposure evaluation According to 447498 D04 Interim General RF Exposure Guidance v01 2.1.2 1-mW Test Exemption Per §1.1307(b)(3)(i)(A), a single RF source is exempt RF device (from the requirement to show data demonstrating compliance to RF exposure limits, as previously mentioned) if the available maximum time- averaged power is no more than 1 mW, regardless of separation distance. 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 Field strength = 73.75dBμV/m @3m Antenna gain=0dBi So EIRP=73.75-95.2=-21.45dBm 10^-21.45=0.0072 mW<1 mW Then SAR evaluation is not required
