RF EXPOSURE EVALUATION According to FCC 1.1310: 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 §1.1307(b) FCC ID: OXGAL96 EUT Specification EUT Show Home App Light Ball Frequency band WLAN: 2.412GHz ~ 2.462GHz (Operating) WLAN: 5.18GHz ~ 5.32GHz / 5.50GHz ~ 5.70GHz WLAN: 5.745GHz ~ 5825GHz Others Device category Portable (<20cm separation) Mobile (>20cm separation) Others ___ Exposure classification Occupational/Controlled exposure (S = 5mW/cm2) General Population/Uncontrolled exposure (S=1mW/cm2) Antenna diversity Single antenna Multiple antennas Tx diversity Rx diversity Tx/Rx diversity Antenna gain (Max) 0.5 dBi Evaluation applied MPE Evaluation SAR Evaluation Limits for Maximum Permissible Exposure(MPE) Frequency Electric Field Magnetic Field Power Average Range(MHz) Strength(V/m) Strength(A/m) Density(mW/cm2) Time (A) Limits for Occupational/Control Exposures 300-1500 -- -- F/300 6 1500-100000 -- -- 5 6 (B) Limits for General Population/Uncontrol Exposures 300-1500 -- -- F/1500 6 1500-100000 -- -- 1 30

Friis transmission formula: Pd=(Pout*G)\(4*pi*R2) 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 the limit of MPE, 1mW/cm2. If we know the maximum gain of the antenna and total power input to the antenna, through the calculation, we will know the distance where the MPE limit is reached.
