Intertek Testing Services ETL SEMKO FCC ID. : M4Y-0XG950 Report No.: EME-030876 Page 4 of 6 1. Introduction The EUT operates in the 2.4GHz ISM band. Due to the EUT (include antenna) at its normal operation distance is at least 20 cm from the human body, the EUT was defined as a Mobile Device. The reason to do the MPE Evaluation is to avoid the RF hazard to human body. The maximum output power and gain of the antenna were used to calculate the limited Power density (S) at 20cm distance away from the product. The limit for Maximum Permissible Exposure (MPE) specified in FCC 1.1310 is followed. 2. RF Exposure Limit According to FCC 1.1310: The criteria listed in the following table shall be used to evaluate the environmental impact of human exposure to radio-frequency (RF) radiation as specified in 1.1307(b). Limits for Maximum Permissible Exposure (MPE) Frequency Electric Field Magnetic Field Power Density Average Time Range Strength Strength (mW/cm2) (minutes) (MHz) (V/m) (A/m) (A) Limits for Occupational / Control Exposures 30-300 61.4 0.163 1.0 6 300-1500 - - F/300 6 1500-100,000 - - 5 6 (B) Limits for General Population / Uncontrolled Exposure 30-300 27.5 0.073 0.2 30 300-1500 - - F/1500 30 1500-100,000 - - 1.0 30 F= Frequency in MHz

RF Exposure calculations From §FCC 1.1310 table 1, the maximum permissible RF exposure for an uncontrolled environment is 1mW/(cm?) Power density (S8) is calculated by the following formula: S = (P * G)/4RR where, S = Power density (mW/cm?) P = Output power to antenna (mW) R = Distance between radiating structure and observation point (¢cm) G = Gain of antenna in numeric T = 3.1416 Example: Assume a mobile device operates at 2412MHz and its maximum output power is 5OmW, and the maximum gain of antenna is 1 (numeric) /0dBi. then the power density (S) = (50 * 1)/4*z*20 = 0.00995 (mW/cm?) 4.
