Shenzhen Huaxia Testing Technology Co., Ltd Report No.: CQASZ20190500017EX-02 5 RF Exposure Evaluation 5.1 RF Exposure Compliance Requirement 5.1.1 Limits According to FCC Part1.1310: 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 part1.1307(b) F= Frequency in MHz Friis Formula 2 Friis transmission formula: Pd = (Pout*G)/(4* Pi * R ) Where Pd = power density in mW/cm2 Pout = output power to antenna in mW G = gain of antenna in linear scale Pi = 3.1416 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. 5.1.2 Test Procedure Software provided by client enabled the EUT to transmit and receive data at lowest, middle and highest channel individually.
