$Dongguan Nore Testing Center Co., Ltd. Report No.: NTC1805215F-1 FCC ID: 2AQY5-IPVDW01 Friis transmission formula: Pd=(Pout*G)\(4*pi*R2) Where Pd= Power density in mW/cm2 Pout=output power to antenna in Mw G= gain of antenna in linear scale Pi=3.1416 R= distance between observation point and center of the radiator in cm Pd the limit of MPE, 1mW/cm2. If we know the maximum gain of the antenna and total power input to the antenna, through the calculation, we will know the distance where the MPE limit is reached.
