MPE Calculations Page 1 of 1 For RF Exposure Requirements Radio Bluetooth Unicellular Model: BT261159P MAXIMUM PERMISSIBLE EXPOSURE FOR SUBPART C 2.4 GHz BAND Calculations Power density at the specific separation: S = PG/(4R2π) S = (0.4943* 1.995) / (4 * 12 * π) S = 0.0784736126 mW/cm2 (at 1 cm) Limit = 1 mW/cm2 where S = Maximum power density (mW/cm2) P = Power input to the antenna (mW) = -3.06 dBm G = Numeric power gain of the antenna R = distance to the center of the radiation of the antenna (1 cm = limit for MPE) The maximum permissible exposure (MPE) for the general population is 1 mW/cm2. The power density at 1 cm does not exceed the 1 mW/cm2. Therefore, the exposure condition is compliant with FCC rules. The numeric gain (G) of the antenna with a gain specified in dB is determined by: G = Log-1 (dB antenna gain/10) G = Log-1 (3 dBi/10) G = 1.995
