Maximum Permissible Exposure(Mpe) Calculation - JRC NTG-420 Installation Manual

Maximum Permissible Exposure(MPE) Calculation

The MPE was calculated with the antenna used as the highest antenna gain which may be used.
Radiofrequency radiation exposure limits.(Frequency: 10MHz to 300GHz)
Limits for Occupational/Controlled Exposure(mW/cm
Limits for General Population/Uncontrolled Exposure(mW/cm
