Note 3: The limit value 1.0mW/cm2 is available for this EUT. MPE CALCULATION METHOD 2 S =PG/(4πR ) where: S = power density (in appropriate units, e.g. mW/ cm2) P = power input to the antenna (in appropriate units, e.g., mW) 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 (appropriate units, e.g., cm) Page 5 of 6 UL Verification Services (Guangzhou) Co., Ltd, Song Shan Lake Branch This report shall not be reproduced except in full, without the written approval of UL Verification Services (Guangzhou) Co., Ltd, Song Shan Lake Branch. .
