Report No.: NTC2101263F-1 FCC ID: 2AYP9-KMHSB003 Friis transmission formula: Pd=(Pout*G)\(4*pi*R 2 ) Where Pd= Power density in mW/cm 2 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.
