FCC ID: U8D-FB900AS MPE Calculations The EUT will only be used with a separation of 20 centimeters or greater between the antenna and the body of the user. The MPE calculation for this exposure is shown below. The peak radiated output power (EIRP) is calculated as follows: EIRP = P + G EIRP = 14.74 dBm + 4.0 dBi EIRP = 18.74 dBm Where, P = Power input to the antenna (mW) G = Power gain of the antenna (dBi) Power density at the specific separation: S = PG/(4R 2 π) S = (29.78 * 2.51) / (4 * 20 2 * π) S = 0.0149 mW/cm 2 Where, S = Maximum power density (mW/cm 2 ) P = Power input to the antenna (mW) G = Numeric power gain of the antenna R = Distance to the center of the radiation of the antenna (20cm) Conclusion: The Maximum permissible exposure (MPE) of the general Population/Uncontrolled for this device is 1.0 mW/cm 2 . The power density at 20cm does not exceed the 1.0 mW/cm 2 . Therefore, the exposure condition of the EUT is compliant with FCC rules. Estimated safe separation: R = √(PG / 4π) R = √(30.55 * 2.50 / 4π) R = 2.44 cm Where, P = Power input to the antenna (mW) G = Numeric power gain of the antenna R = Distance to the center of the radiation of the antenna (20cm = limit for MPE) The numeric gain(G) of the antenna with a gain specified in dB is determined by: G = Log -1 (dB antenna gain / 10) G = Log -1 (4.0 / 10) G = 2.51
