RF Exposure FCC ID: XMF-CVD1662 Report No.: LP23080282C01-35-1 Page 1/3 SAR EVALUATION F= Frequency in MHz Friis Formula Friis transmission formula: Pd = (Pout*G)/(4* Pi * R 2) 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. Test Procedure: Software provided by client enabled the EUT to transmit and receive data at lowest, middle and highest channel individually.
