RF Exposure This calculation is based on the highest EIRP possible from the EUT considering maximum power and antenna gain. The highest output power of the EUT is 0.927 W and the gain of the antenna is 3 dBi. The max duty cycle is one transmission (100 mS) every 6 minutes. So the maximum percentage is 0.1/360 which is 0.0277 % The output power is 0.927 Watts. 0.927 W * 0.000277 = 0.257 mW. Accounting for the antenna, 3 dBi is equivalent to a multiplier of 2.0, so the average power = 0.514 mW 1 MINIMUM SEPARATION DISTANCE PER OET 65 The following information provides the minimum separation distance for the EUT, as calculated from FCC OET 65 Appendix A, Table B “Guidelines for General Population/Uncontrolled Exposure” MPE Max (S) GP Ratio Transmitt Power Max Ant Duty Limit MSD from 20 er MHz dBm Gain dBi Cycle % EIRP W mW/cm^2 Meters cm Notes 450-470 450 29.7 3 0.0277 0.00051 0.300 0.0037 0.018 Total MPE Ratio 0.018 Notes on the above table: a. S is the power density General Population Limit from OET 65 table B b. EIRP Power is the Max Power corrected for Antenna Gain and Duty Cycle factor c. MSD (Minimum Separation Distance) = ((EIRP*30)/3770*S)^0.5 d. For mobile or fixed location transmitters, minimum separation distance is 20 cm, even if calculations indicate MPE distance is less. 2 RF EVAULATION FOR RSS-102E Since the average e.i.r.p. is 0.00051 Watts and separation distance between the user and the radiating element of the device is always greater than 20 cm, it is exempt from routine SAR and RF exposure evaluations. 2.1 SAR Evaluation Exemption for RSS-102 Since the separation distance between personnel and the antenna is greater than or equal to 20 cm, it is exempt from routine SAR evaluations in accordance to Section 2.5.1 of RSS-102 issue 5, table 1. 2.2 RF Evaluation Exemption for RSS-102 Since the separation distance between personnel and the antenna of the device is greater than or equal to 20 cm AND the power is less than 0.852 watts, it is exempt from RF evaluation as per RSS-102 section 2.5.2. Average Limit for Exemption Transmitter EIRP RSS-102 Transmitter MHz W Max EIRP mW Result Business 450 0.00051 0.852 Exempt from SAR and RF exposure Authorized Agent: Radiometrics Midwest Corporation (815) 293-0772
