R = distance to the center of radiation of the antenna (in appropriate units, e.g., cm)

1.4 MPE Calculation Result Maximum Tune-Up output power: 17 (dBm) Maximum peak output power at antenna input terminal: 50.12 (mW) Prediction distance: >20(cm) Prediction frequency: 2412 (MHz) Antenna gain: 1.2 (dBi) Directional gain (numeric gain): 1.32 The worst case is power density at prediction frequency at 20cm: 0.013(mw/cm2) MPE limit for general population exposure at prediction frequency: 1 (mw/cm2) Result: Pass
