GENERAL INFORMATION 1.1 GENERAL DESCRIPTION OF THE EUT Product Name Smart Key Brand Name N/A Model Name RT-TYBDP Series Model(s) N/A Model Difference N/A Product Description The EUT is Smart Key Operation Frequency: 315MHz Modulation Type: FSK Antenna gain: -12.88 dBi Antenna Designation: PCB Antenna Power Rating DC 3V Adapter N/A Battery DC 3.0V (CR2032 battery) Hardware Version N/A Software Version N/A 1.2 TEST FACTORY SHENZHEN STS TEST SERVICES CO., LTD Add. : 101, Building B, Zhuoke Science Park, No.190 Chongqing Road, ZhanChengShequ, Fuhai Sub-District, Bao’an District, Shenzhen, Guang Dong, China FCC test Firm Registration Number: 625569 FCC test Firm Designation Number: CN1203 IC test Firm Registration Number: 12108A A2LA Certificate No.: 4338.01 Page 6 of 8 Report No.: STS2601270H01 2. 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.: STS2601270H01 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.: STS2601270H01 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 315(FSK) 0.315 5 -6.9 0.203 0.02 Yes / Note: 1. Remark: The worst case gain of the antenna is -12.88 dBi. 2. Threshold at which no SAR required is 0.02 ≤ 7.5 for 10-g SAR, Separation distance ≤ 5mm. ※※※※※END OF THE REPORT※※※※※ Frequency (MHz) Maximum field strength@3m ( dBuV/m) Maximum field strength@3m (V/m) Antenna Gain (dBi) Antenna Gain (numeric) Distance (m) Output power ( dBm ) 315 75.43 0.0059 -12.88 0.052 3 -6.9
