Limits The criterialistedin the followingtableshallbe usedto evaluatethe environmentimpactof humanexposureto radiofrequency(RF)radiationas specifiedin 1.1307(b) Limitsfor MaximumPermissibleExposure(MPE) f = frequencyin MHz Friistransmissionformula:Pd = (Pout*G)/(4*pi*r 2 ) Where Pd= powerdensityin mW/cm 2 ,Pout= outputpowerto antennain mW; G= gain of antennain linearscale,Pi= 3.1416; R= distancebetweenobservationpointand centerof the radiatorin cm Pd id the limit of MPE,1 mW/cm 2 . If we knowthe maximumgainof the antennaand the total powerinputto the antenna,throughthe calculation,we will knowthe distancer wherethe MPE limit is reached. FCCID: R48-TT025 1.2.
