MPE calculation

S = EIRP / (4πR2)
Where          S : Power density
               EIRP : P x G
               P : Maximum transmitter power
               G : Antenna gain
               R : distance to the centre of radiation of the antenna

EUT RF Exposure

                P : 5.64 dBm (3.664 mW)
                G : 2.97 (x 1.982)
                R : 20 cm

                S = 0.0014453 mW/cm2


Conclusion
This confirms compliance to the required Radio frequency radiation exposure limit.
