G=power gain of the antenna in the direction of interest relative to an isotropic radiator R=distance to the center of radiation of the antenna in cm Conducted power see the test report DLE-260128001R, antenna gain=0.53dBi. When the minimum test separation distance is >20 cm, a distance of 20 cm is applied to determine RF Exposure test exclusion. The test exclusion threshold is 0.00028mW/cm 2 which is< 1.0 mW/cm 2 , RF Exposure testing is not required. -------The End-------
