Global United Technology Services Co., Ltd. FCC ID: 2AJOF-ATOM600KG-TX RF Exposure Evaluation 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) Frequency range (MHz) Electric field strength (V/m) Magnetic field strength (A/m) Power density (mW/cm 2 ) Averaging time (minutes) (A) Limits for Occupational/Controlled Exposures 0.3–3.0 614 1.63 *(100) 6 3.0–30 1842/f 4.89/f *(900/f 2 ) 6 30–300 61.4 0.163 1.0 6 300–1500 f/300 6 1500–100,000 5 6 (B) Limits for General Population/Uncontrolled Exposure 0.3–1.34 614 1.63 *(100) 30 1.34–30 824/f 2.19/f *(180/f 2 ) 30 30–300 27.5 0.073 0.2 30 300–1500 f/1500 30 1500–100,000 1.0 30 f = frequency in MHz Friis transmission formula: Pd = (Pout*G)/(4*pi*r 2 ) Where Pd = power density in mW/cm 2 , 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/cm 2 . 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, and highest channel individually. Global United Technology Services Co., Ltd. Test Result of RF Exposure Evaluation Channel Output power to antenna (mW) Power Density at R=20cm (mW/cm 2 ) Limit (mW/cm 2 ) Result ANT 1 ANT 2 ANT 1 ANT 2 SUN 5180MHz 32.734 29.512 0.012 0.012 0.024 1.0 PASS 5240MHz 29.785 29.107 0.012 0.011 0.023 1.0 PASS 5745MHz 17.824 17.824 0.007 0.007 0.014 1.0 PASS 5825MHz 18.030 18.030 0.007 0.007 0.014 1.0 PASS Remark: antenna gain=2.96dBi The max power density is less than SAR exempt limit, so SAR evaluation is not required.
