Standalone SAR test exclusion considerations Unless specifically required by the published RF exposure KDB procedures, standalone 1-g head or body and 10-g extremity SAR evaluation for general population exposure conditions, by measurement or numerical simulation, is not required when the corresponding SAR Exclusion Threshold condition, listed below, is satisfied. 2.1.2 Limits The 1-g and 10-g SAR test exclusion thresholds for 100 MHz to 6 GHz at test separation distances ≤ 50 mm are determined by: [(max. power of channel, including tune-up tolerance, mW)/(min. test separation distance, mm)] · [√f(GHz)] ≤ 3.0 for 1-g SAR and ≤ 7.5 for 10-g extremity SAR, where f(GHz) is the RF channel transmit frequency in GHz Power and distance are rounded to the nearest mW and mm before calculation 17 The result is rounded to one decimal place for comparison The test exclusions are applicable only when the minimum test separation distance is ≤ 50 mm and for transmission frequencies between 100 MHz and 6 GHz. When the minimum test separation distance is < 5 mm, a distance of 5 mm is applied to determine SAR test exclusion Report No.: MTEB23070051-H Page 5 of 5 2.1.3 EUT RF Exposure EIRP =PT*GT= (E x D)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 (dBμV/m)/20) /10 6 , D = measurement distance in meters (m)---3m, So PT = (E x D)²/30 / GT The worst case (refer to report MTEB23070051) is below: Antenna polarization: Horizontal Frequency (MHz) Level (dBuV/m) Polarization 433.72 73.69 Peak 433.72 65..93 Average Antenna polarization: Vertical Frequency (MHz) Level (dBuV/m) Polarization 433.72 74.96 Peak 433.72 67.20 Average For 433.72MHz wireless: Field strength=74.96 dBuV/m Ant gain-1.77dBi;so Ant numeric gain=0.66 EIRP = PT*GT = (E x D)²/30=(10 (dBμV/m)/20) /10 6 *3) 2 /30=0.00094 So PT= EIRP/GT=0.0000108W=0.00142mW So(0.00142mW/5mm)* √0.43392GHz=0.0019 exclusion=0.0019<3.0 for 1-g SAR So the SAR report is not required.
