FCC ID: 2APUZ-WP3 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) Limits for Maximum Permissible Exposure (MPE) MPE Calculation Method E (V/m) ＝ d GP**30 Power Density: Pd (W/m²) ＝ 377 2 E E ＝ Electric field (V/m) P ＝ Average RF output power (W) G ＝ EUT Antenna numeric gain (numeric) d ＝ Separation distance between radiator and human body (m) The formula can be changed to Pd ＝ 2 *377 **30 D GP From the EUT RF output power, the minimum mobile separation distance, d=0.2m, as well as the gain of the used antenna, the RF power density can be obtained. Measurement Result Operation Frequency: WIFI: 2412-2462MHz Power density limited: 1mW/ cm 2 Antenna Type: PCB Antenna Antenna gain: 1.5dBi, R=20cm conducted power Evaluation result Power density Limits (dBm)(mW)(dBi)Numeric 2412 9.66 9±110 10.0001.501.410.00281 2437 9.71 9±110 10.0001.501.410.00281 2462 9.51 9±110 10.0001.501.410.00281 2412 6.49 7±18 6.3101.501.410.00181 2437 6.01 7±18 6.3101.501.410.00181 2462 6.61 7±18 6.3101.501.410.00181 2412 6.22 7±18 6.3101.501.410.00181 2437 6.31 7±18 6.3101.501.410.00181 2462 6.31 7±18 6.3101.501.410.00181 Channel Freq.
