FCC ID: 2ATPOESP-12L 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 30 * P * G E2 E (V/m) ＝ Power Density: Pd (W/m²) ＝ d 377 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 30 * P * G Pd ＝ 377 * D 2 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: 2412-2462MHz for 802.11b/g/11n(HT20); Power density limited: 1mW/ cm2 Antenna Type: PCB Antenna Antenna gain: 2 dBi R=20cm WIFI: Power conducted Evaluation Max Antenna density Channel power Tune-up result modulation Limits Freq.
