CERPASS TECHNOLOGY CORP. Report No.: 1907135 FCC RF EXPOSURE REPORT EUT WiFi/BT Module FCC ID 2AFG6-WF-R22C-USA1 Portable (<20cm separation) Device category Mobile (>20cm separation) Occupational/Controlled exposure (S = 5mW/cm2) Exposure classification General Population/Uncontrolled exposure (S=1mW/cm2) Single antenna Multiple antennas Antenna diversity Tx diversity Rx diversity Tx/Rx diversity MPE Evaluation* Evaluation applied SAR Evaluation N/A TEST RESULTS No non-compliance noted. Calculation 30  P  G E2 Given E & S d 3770 Where E = Field strength in Volts / meter P = Power in Watts G = Numeric antenna gain d = Distance in meters S = Power density in milliwatts / square centimeter Combining equations and re-arranging the terms to express the distance as a function of the remaining variables yields: 30  P  G S 3770d 2 Changing to units of mW and cm, using: P (mW) = P (W) / 1000 and d (cm) = d(m) /100 Yields 30  P / 1000  G PG S  0.0796  2 Equation 1 3770  d / 100 2 d Where d = Distance in cm P = Power in mW G = Numeric antenna gain S = Power density in mW / cm2 Cerpass Technology (Suzhou) Co., Ltd.
