Computational Analysis of EMF Standards for Cellular Networks

Compliance to EMF Norms (Electromagnetic Field) is very critical for Cellular Networks. There is a need to compare the EMF standards and RF Energy with tangible references of electromagnetic waves including Sun Light to put things in right perspective. Computational Analysis for EMF Standards for Macro cells with emphasis on Small Cells (FEMTO Cells) has been presented for two different models and comparative analysis is included. It is shown that the Free Space Path Loss Model can be effectively used to estimate the Power Density in near field regions wherein compliance to EMF Standard needs to be computed as critical requirement as beyond which compliance would then be achieved in any case. Comparison of energy absorbed from RF Waves in a finite time with Sunlight in line of sight scenario as a worst case analysis with actual measurement results for the model used has been done to show that the RF energy we are exposed to is minuscule. Safety is achieved in three ways - by the inherently lower energy of the photon itself leading to its non ionizing nature, the decay of RF Waves with distance and by the limit on total power by the EMF standards. All analysis must be based on RF Energy in actual areas of public access wherein the decay of RF waves with distance is an important factor and further ensures compliance of safety norms by many multiple times.
