RF Exposure Info

FCC ID:2BV7Z-G07 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 0.3–3.06141.63*(100)6 3.0–301842/f4.89/f*(900/f 2 )6 30–30061.40.1631.06 300–1500f/3006 1500–100,00056 (B) Limits for General Population/Uncontrolled Exposure 0.3–1.346141.63*(100)30 1.34–30824/f2.19/f*(180/f 2 )30 30–30027.50.0730.230 300–1500f/150030 1500–100,0001.030 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, middle and highest channel individually. Test Result of RF Exposure Evaluation Modulation Frequency (MHz) Output power to antenna (dBm) Output power to antenna (mW) Power Density at R=20cm (mW/cm 2 ) Limit (mW/cm 2 ) Result 802.11b 241215.9939.7191550.0141821.0PASS 243717.5456.7544610.0202641.0PASS 246217.2953.5796660.0191311.0PASS 802.11g 241215.4835.3183170.0126101.0PASS 243717.2352.8445250.0188681.0PASS 246217.0851.0505000.0182281.0PASS 802.11n20 241215.1832.9609710.0117691.0PASS 243717.4155.0807700.0196671.0PASS 246217.2252.7229860.0188251.0PASS 802.11n40 242214.2726.7300640.0095441.0PASS 243716.3242.8548520.0153011.0PASS 245216.0540.2717030.0143791.0PASS Remark：WIFI Antenna gain is 2.54 dBi So a SAR test is not required
