2. MPE CALCULATION METHOD Calculation Method of RF Safety Distance: where: S = power density P = power input to the antenna G = power gain of the antenna in the direction of interest relative to an isotropic radiator R = distance to the center of radiation of the antenna Ant. Brand Model Name Antenna Type Connector Gain (dBi) 1 N/A N/A Dipole N/A 4 2 N/A N/A Dipole N/A 4 Note: The EUT incorporates a MIMO function. Physically, the EUT provides two completed transmitters and receivers (2T2R), all transmit signals are completely correlated, then, Direction gain = GANT+10log(N)dBi=4+10log(2), that is Directional gain=7.01. So, the out power limit is 30-7.01+6=28.99, the power density limit is 8-7.01+6=6.99. 3. TEST RESULTS Antenna Power Limit of Power Antenna Gain AVG Output AVG Output Test Gain Density (S) Density (S) (numeric) Power (dBm) Power (mW) Result (dBi) (mW/cm2) (mW/cm2) 7.01 5.0234 23.01 199.9862 0.19996 1 Complies Note: the calculated distance is 20 cm.
