The power density according to far-field model is: 2 ),( 4R GP S      Where: P = input power of the antenna. G = antenna gain relative to an isotropic antenna. , = elevation and azimuth angles. R = distance from the antenna to the point of investigation. 2. For single or multiple RF sources, the calculated power density should comply with following: 1 ,   i iLimit i S S Where: i S = the power density when the f is i . iLimit S , = the reference level requirement for power density when f is i . f = operating frequency. 3. The calculation of the power density or safe distance is: NOTE 1: The RF exposure evaluation is base on the far-field and the radiation exposure is over-estimated. NOTE 2: The maximum output power level is taken into account as a worst case for the purpose of the calculation of power density or safe distance. NOTE 3: The minimum antenna feed cable loss (assumed no cable loss) is taken into account as a worst case for the purpose of the calculation of power density or safe distance. NOTE 4: The maximum antenna radiation exposure orientation and maximum antenna gain is taken into account as a worst case for the purpose of the calculation of power density or safe distance.
