ATTACHMENT FCC ID: RQKWUBR-506N ** MPE Calculations ** **2.4GHz Bands Worst Case of 802.11n(40MHz) 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 = 19.11dBm + (2.5)dBi EIRP = 21.61dBm 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 = (81.47* 1.78) / (4 * 20 2 * π) S = 0.0288mW/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 at 20cm does not exceed the 1 mW/cm 2 limit. Therefore, the exposure condition is compliant with FCC rules. Estimated safe separation: R = √(PG / 4π) R = √(81.47* 1.78/ 4π) R = 3.4Cm 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 ((2.5) / 10) G = 1.78 ATTACHMENT FCC ID: RQKWUBR-506N ** MPE Calculations ** **5.0GHz Bands Worst Case of 802.11an(20MHz) 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 = 15.98 dBm + (5.0)dBi EIRP = 20.98dBm 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 = (39.63 * 3.16) / (4 * 20 2 * π) S = 0.0249 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 at 20cm does not exceed the 1 mW/cm 2 limit. Therefore, the exposure condition is compliant with FCC rules. Estimated safe separation: R = √(PG / 4π) R = √(39.63 * 3.16/ 4π) R = 3.16Cm 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 ((5.0) / 10) G = 3.16
