Evaluation of Techniques for the Reduction of Electromagnetic Power Density around Future Base Stations

Abstract

Electromagnetic (EM) emission poses danger to the health of both man and animals. The future generations of cellular networks poses’ higher threats of EM emissions. Evaluation of various techniques for the reduction of EM radiations around base station has become a front burner issue. With the risen awareness in wireless communication technology capabilities, the need to increase speed and bandwidth became necessary in order to accommodate the ever increasing connectivity.  Hence, the inherent EM emissions that come along with the technologies have necessitated the search for better techniques to reduce the electromagnetic interference (EMI). Considering the current EMI concerns, the base station is the hub of the interference. This research examined different techniques of reducing the EM power density around the base station such as the grounding, the filtering and the shielding. The result indicated that among these three techniques examined, the filtering techniques gives the least  reduction of EM power density of 3.552Wm^-2 as compared with the shielding which gives 3.755 Wm^-2 and grounding with 3.783 Wm^-2  all at a distance of 10m each.
