RF Exposure / MPE Calculation Dear Reviewer, As specified in Table 1B of 47 CFR 1.1310 – Limits for Maximum Permissible Exposure(MPE), Limits for General Population/Uncontrolled Exposure: The RF Exposure level is calculated using the general equation: S = P/ 4πR2 The maximum measured radiated power output is CDMA 800MHz: 23.95 dBm (~ 0.24831 W) CDMA1900MHz: 24.04 dBm (~ 0.25293 W) With an antenna gain of 800MHz ： 0.8 dBi 1900MHz ：3.0 dBi R = 20 cm π = 3.1416 Solving for S, the power density at 20 cm is CDMA800: 0.0494 mW/cm2 CDMA1900: 0.0504 mW/cm2 The power density limit is: For 800MHz: f/1500 = 824.7/1500 = 0.5498 mW/cm2 For 1900MHz: 1.0 mW/cm2 So, the power density limit is well kept with this antenna gain. Please contact us if you have any additional questions. Best Regards Morlab ZhangWenjie
