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 Table for Filed Antenna: For 2.4GHz: Ant. Brand Model Name Antenna Type Connector Gain (dBi) 1 N/A Dipole N/A 1.8 2 N/A Dipole N/A 1.8 3 N/A Dipole N/A 1.8 Note: This EUT supports CDD, and all antennas have the same gain, Directional gain = GANT+Array Gain, where Array Gain is as follows: (1) Non-Beamforming function, For power spectral density measurements, NANT = 3, NSS = 1. So Directional gain = GANT + Array Gain =10 log (NANT/ NSS) dB =1.8+10log(3/1)dBi=6.57. Then, the power density limit is 8-(6.57-6)=7.43. For power measurements, Array Gain = 0 dB (NANT ≤ 4), so the Directional gain=1.8. (2) Beamforming function, Beamforming Gain: 4.77 dB. So Directional gain = 4.77+1.8=6.57. Then, the average output power limit is 30-(6.57-6)=29.43. The power density limit is 8-(6.57-6)=7.43. For 5GHz: Ant. Brand Model Name Antenna Type Connector Gain (dBi) Note 1 N/A Dipole N/A 1.8 UNII-1 2 N/A Dipole N/A 1.8 UNII-1 3 N/A Dipole N/A 1.8 UNII-1 4 N/A Dipole N/A 1.8 UNII-3 5 N/A Dipole N/A 1.8 UNII-3 6 N/A Dipole N/A 1.8 UNII-3 Note: This EUT supports CDD, and all antennas have the same gain, Directional gain = GANT+Array Gain, where Array Gain is as follows: (1) Non-Beamforming function, For power spectral density measurements, NANT = 3, NSS = 1. So Directional gain = GANT + Array Gain =10 log (NANT/ NSS) dB =1.8+10log(3/1)dBi=6.57. Then, the UNII-1 power spectral density limit is 17-6.57+6=16.43, the UNII-3 power density limit is 30-6.57+6=29.43. For power measurements, Array Gain = 0 dB (NANT ≤ 4), so the Directional gain=1.8. (2) For Beamforming function, Beamforming Gain: 4.77 dB. So Directional gain = 4.77+1.8=6.57. Then, the UNII-1 and UNII-3 output power limit is 30-6.57+6=29.43; the UNII-1 power density limit is 17-6.57+6=16.43, the UNII-3 power density limit is 30-6.57+6=29.43.
