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 Table for Filed Antenna 2.4G Ant. Brand Model Name Antenna Type Connector Gain(dBi) 1 N/A N/A PCB N/A 4.5 2 N/A N/A PCB N/A 4.5 Note: The EUT incorporates a MIMO function. Physically, the EUT provides two completed transmitters and receivers (2T2R), all transmit signals are completely correlated, then, for Non-beamforming function, Direction gain = GANT+10log(N)dBi=4.5+10log(2), that is Directional gain=7.51. So, the out power limit is 30-7.51+6=28.49, the power density limit is 8-7.51+6=6.49, for beamforming function, Beamforming Gain=3 dBi, Direction gain = 7.51, So, the out power limit is 30-7.51-3+6=25.4 the power density limit is 8-7.51-3+6=3.49

Manufacturer Model Name Antenna Type Connector Gain(dBi) Note 1 N/A N/A PCB N/A 4 UNII-1 1 N/A N/A PCB N/A 4.5 UNII-3 2 N/A N/A PCB N/A 4 UNII-1 2 N/A N/A PCB N/A 4.5 UNII-3 Note: The EUT incorporates a MIMO function. Physically, the EUT provides two completed transmitters and receivers (2T2R), all transmit signals are completely correlated, then, For Non-beamforming function, Direction gain = 10 log[(10G1/20 + 10G2/20)2/N], that are UNII-1 Directional gain=10 log[(104/20 + 10 4/20)2/2] = 7.01dBi UNII-3 Directional gain=10 log[(104.5/20 + 10 4.5/20)2/2] =7.51dBi The UNII-1 Output Power limit is 30-7.01+6=28.99dBm The UNII-3 Output Power limit is 30-7.51+6=28.49dBm The UNII-1 PSD limit is 17-7.01+6=15.99dBm/MHz The UNII-3 PSD limit is 30-7.51+6=28.49dBm/500kHz. For beamforming function, Beamforming Gain=3 dBi, UNII-1 Directional gain = 7.01dBi UNII-3 Directional gain =7.51dBi The UNII-1 Output Power limit is 30-7.01-3+6=25.99dBm The UNII-3 Output Power limit is 30- 7.51-3+6=25.49dBm, The UNII-1 PSD limit is 17-7.01-3+6=12.99dBm/MHz, The UNII-3 PSD limit is 30-7.51-3+6=25.49dBm/500kHz.
