Equation for predicting RF field was used to determine the maximum antenna gain that can be used with the EUT and still comply with the requirements:  = 4  Where: S=the power flux P=input power of the antenna G=antenna gain relative to an isotropic antenna r=distance from the antenna to the point of investigation From this formula, for LTE Band 12, using 0.230329 mW/cm2 as S (worst case than FCC limit), 20 cm as r then the antenna gain G is calculated. This is the maximum antenna gain in dBi that can be used with the EUT while still in compliance with the power density requirements. 4   =  4 20  0.230329 /   = 316.0  1157.76 = 316.0   = 3.664 Therefore: G = 3.66 dBi for Band 12, G = 6.75 dBi for Band 4 G = 3.94 dBi for Band 13 G = 4.41 dBi for Band 5 G = 7.0 dBi for Band 2 Sincerely, Ferdie S.
