Limits The criteria listed in the following table shall be used to evaluate the environment impact of human exposure to radio frequency (RF) radiation as specified in 1.1307(b) Limits for Maximum Permissible Exposure (MPE) F = frequency in MHz Formula: Pd = (Pout*G)/(4**r2) Where : Pd = power density in mW/cm2, Pout = output power to antenna in mW; G = gain of antenna in linear scale, = 3.14; R = distance between observation point and center of the radiator in cm Pd id the limit of MPE, 1 mW/cm2. If we know the maximum gain of the antenna and the total power input to the antenna, through the calculation, we will know the distance r where the MPE limit is reached. 2. Test Procedure Software provided by client enabled the EUT to transmit and receive data at lowest, middle and Flux Compliance Service Laboratory Room 105 Floor Bao hao Technology Building 1 NO.15 Gong ye West Road Hi-Tech Industrial, Song shan lake Dongguan Tel: 769-27280901 Fax:769-27280901 http://www.FCS-lab.com Page 2 of 2 Report No.: FCS202307132W01 highest channel individually. 3.
