FCC ID: 2AYOQ-LC-RGBV2 Maximum Permissible Exposure (MPE) 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 G P * * 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 G P 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. BLE: Measurement Result Operation Frequency: 2402MHz~2478MHz Antenna gain: 0dBi; R=20cm conducted power Evaluation result Power density Limits (dBm) (mW) (dBi) Numeric 2402 -4.18 -4±1 -3 0.501 0.00 1.00 0.0001 1 2440 -4.88 -4±1 -3 0.501 0.00 1.00 0.0001 1 2478 -4.51 -4±1 -3 0.501 0.00 1.00 0.0001 1 tune-up power Gain Channel Freq.
