   5745-5825              931.576        7.13                    29     0.45521                1

NOTE:
2.4GHz: Directional gain = 6.49dBi
5GHz: Directional gain = 7.13dBi


Conclusion:
The formula of calculated the MPE is:
CPD1 / LPD1 + CPD2 / LPD2 + ……etc. < 1
CPD = Calculation power density
LPD = Limit of power density


WLAN 2.4GHz + WLAN 5GHz = 0.39734 / 1 + 0.45521 / 1 = 0.85255
Therefore the maximum calculations of above situations are less than the “1” limit.
