RF Exposure Evaluation FCC KDB447498 D01 General RF Exposure Guidance v06: Mobile and Portable Device, RF Exposure, Equipment Authorization Procedures. FCC CFR 47 part1 1.1310: Radiofrequency radiation exposure limits. FCC CFR 47 part2 2.1091: Radiofrequency radiation exposure evaluation: mobile devices. 2.1 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 Friis transmission formula: Pd = (Pout*G)/(4* Pi * R 2) Where Page 1 of 1 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 . 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. 2.2 EUT RF EXPOSURE EVALUATION BT ANT1: 2.34dBi; Test channel (MHz) Conducted Power (dBm) Tune-up (dbm) Maximum tune-up Power (dbm) Maximum tune-up Power (mW) Calculated value (mW/cm 2 ) Limit (mW/cm 2 ) 2402 5.54 6±1.0 7.0 5.012 0.00171 1.0 2440 5.37 6±1.0 7.0 5.012 0.00171 1.0 2480 5.64 6±1.0 7.0 5.012 0.00171 1.0 Remark: 1.Pd = (Pout*G)/(4* Pi * R 2 )=( 5.012*1.714)/(4*3.1416*20*20)= 0.00171, G=10 gain/10 =1.714 2. EUT BT module is more than 20cm away from the human body. 2.3 Conclusion Calculated value is less than the limit value of 1.0mW/cm 2 , so there is no sar requirement.
