Abstract

Compliance to EMF Standards (Electromagnetic Fields) is usually ascertained using prediction models for power density of Radio Frequency (RF) Waves. In case these give a result as higher than the permitted value, field measurements of power density are then carried out. An analysis of prediction models being used has been presented for different accessibility criteria. Estimation for near field regions has been done for Cellular Frequencies. The most critical area where compliance needs to be ensured is the near field region of the antenna as beyond which the decay of RF Waves with distance from emitting source is large enough to ensure that Power Density is much below the Standards. The existing models being used lead to large scale but safe side overestimation of Power Density in this region. It is shown that a new method based on the Free Space Path Loss Model can be effectively used to estimate the Power Density in near field regions along with field measurement results. The RF energy decays rapidly with distance near the Cell Site and reaches minuscule values by the time it reaches areas of Public access and the same has been compared with Sun Light as a tangible reference.
