F = Frequency in MHz


2.2     MPE Calculation Formula
Pd = (Pout*G) / (4*pi*r2)
where
Pd = power density in mW/cm2
Pout = output power to antenna in mW
G = gain of antenna in linear scale
Pi = 3.1416
R = distance between observation point and center of the radiator in cm


2.3     Classification
The antenna of this product, under normal use condition, is at least 20cm away from the body of the user. So,
this device is classified as Mobile Device.

Note:
Radio 1: 2.4GHz Band: Directional gain = 10 log[(10G1 /20 + 10G2 /20 + ... + 10GN /20)2/2]= 6.97dBi
Radio 2: 5GHz Band: Directional gain = 10 log[(10G1 /20 + 10G2 /20 + ... + 10GN /20)2/2]= 8.54 dBi

Conclusion:
Both of the WLAN 2.4G & WLAN 5G & BT LE can transmit simultaneously, the formula of calculated the MPE
is:
CPD1 / LPD1 + CPD2 / LPD2 + ……etc. < 1
CPD = Calculation power density
LPD = Limit of power density
Radio 1 + Radio 2 + Radio 3 (2.4G) + Radio 3 (5G) + Radio 4
= 0.183+0.676+0.092+0.039+0.003=0.993
Therefore, the maximum calculation of this situation is 0.993, which is less than the “1” limit.

Note: All radio technologies cantransmit simultaneously, but Radio 1 & Radio 2 & Radio 3 & Radio 4 will not
     simultaneously in the same sub-band.
