FCC 47CFR §2.1093 REQUIREMENT 2.1 TEST STANDARDS The limit for Maximum Permissible Exposure (MPE) specified in KDB 447498 D01 General RF Exposure Guidance v06 is followed. The gain of the antennas used in the product is extracted from the Antenna data sheets provided and also the maximum total power input to the antenna is measured. Through the Friis transmission formula and the maximum gain of the antenna, we can calculate the distance, away from the product, where the limit of MPE is reached. Although the Friis Transmission formula is far field assumption, the calculated result of that is an over-prediction for near field power density. It is taken as worst case to specify the safety range. 2.2 LIMIT Approximate SAR Test Exclusion Power Thresholds at Selected Frequencies and Test Separation Distances are illustrated in the following Table. Page 7 of 8 Report No.: STS2601273H01 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 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. Page 8 of 8 Report No.: STS2601273H01 2.3 TEST RESULT Maximum measured transmitter power. Worst Case According to the calculation formula of power: EIRP = P*G = (E*d) 2 /30 Where: P = transmitter output power in watts, G = numeric gain of the antenna in the direction of interest relative to an isotropic radiator (unitless), E = electric field strength in V/m, --- 10 ((dBuV/m)/20) /10 6 , d = measurement distance in meters (m)---3m, So, P = (E*d) 2 /(30 *G) Evaluation Result Mode Frequency Antenna Distance RF output power including tune up (dBm) SAR Test Exclusion Threshold SAR Test Exclusion Estimated SAR GHz mm dBm mw 433.92(FSK) 0.43392 5 -4.8 0.33 0.04 Yes / Note: 1. Remark: The worst case gain of the antenna is -12.88dBi. 2.
