FCC ID: AZXHDK-2000 ATTACHMENT ** MPE Calculations (2.4GHz)** The MPE calculation for this exposure is shown below. The peak radiated output power (EIRP) is calculated as follows: EIRP = P + G EIRP = 11.49dBm + 3.29dBi EIRP = 14.78 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 ) S = (14.09 *2.13) / (4 * 20 2 * S = 0.006 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 = limit for MPE) The Maximum permissible exposure (MPE) for the general population is 1 mW/cm 2 . The power density does not exceed the 1 mW/cm 2 limit. Therefore, the exposure condition is compliant with FCC rules. Estimated safe separation: R = (PG / 4) R = (14.09* 2.13 / 4) R = 1.55Cm 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 (3.29 / 10) G = 2.13
