Page 9 of 11 Report No.: 180907019RFC-3 3.3 MPE CALCULATION METHOD S = PG/4πR^2= EIRP/4πR^2 S = power density (in appropriate units, e.g., mw/cm2) P = power input to the antenna (in appropriate units, e.g., mw) G = power gain of the antenna in the direction of interest relative to an isotropic radiator, the power gain factor is normally numeric gain. R = distance to the center of radiation of the antenna (in appropriate units, e.g., cm) 3.4 MPE CALCULATION RESULTS Note: For the test results, the EUT had been tested with all conditions.

Both Chain 0 and Chain 1 used at the same time and antenna ports have uniform output powers. The Chain 0 and Chain 1 antenna ports can be used alone. The transmit signals are correlated with each other. For 2.4 GHz WIFI & 5 GHz WIFI Directional gain = 10 log[(10^G1 /20 + 10^G2 /20 + … + 10^GN /20)^2 /NANT] dBi [Note the “20”s in the denominator of each exponent and the square of the sum of terms; the object is to combine the signal levels coherently.] For SISO mode (1Tx/1Rx), there are two transmission antennas. Both Chain 0 and Chain 1 used at the same time and antenna ports have uniform output powers. The Chain 0 and Chain 1 antenna ports cannot be used alone For 2.4 GHz WIFI & 5 GHz WIFI The antenna gain = Chain 0 or Chain 1 Shenzhen UnionTrust Quality and Technology Co., Ltd.
