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 2.4G: Antenna Gain Ant. Brand Model Name Connector Type (dBi) Dongguan City 1 Xinsheng 8000000008581341 Dipole N/A 5 Electronics Co., Ltd Dongguan City 2 Xinsheng 8000000008581341 Dipole N/A 5 Electronics Co., Ltd Note: The EUT incorporates a MIMO function. Physically, the EUT provides two completed transmitters and receivers (2T2R), all transmit signals are completely uncorrelated, then, Direction gain = GANT, that is Directional gain=5. Operating Mode 1TX 2TX TX Mode 802.11b V (ANT 1) - 802.11g V (ANT 1) - 802.11n(20MHz) - V (ANT 1+ANT 2) 802.11n(40MHz) - V (ANT 1+ANT 2) ANT 1 for 1TX was found to be the worst case and recorded.
