The distance from the EUT's transmitting antenna where the exposure level reaches the maximum permitted level is calculated using the general equation: S = P*G / 4πR² Smax = 1mW/cm², P = 1,86 mW, linear power gain relative to the isotropic radiator = 4 dBi = 2,51 (numeric gain), R = distance in cm Solving for R, the 1mW/cm² limit is reached in a distance of 0,61 cm to the transmitting antenna. Please contact us if you have any additional questions.
