FCC ID: 2BDZQ-DGSH-SP003 RF Exposure Evaluation According to KDB 447498 D01 General RF Exposure Guidance v06 and part 2.1091，Unless specifically required by the published RF exposure KDB procedures, standalone 1-g head or body and 10-g extremity SAR evaluation for general population exposure conditions, by measurement or numerical simulation, is not required when the corresponding SAR Test Exclusion Threshold condition(s), listed below, is (are) satisfied. Limits The criteria listed in the following table shall be usedto 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.
