Abstract: Power flux density is the measure of the strength of the high-frequency radiation in the far field, which characterizes the energy flowing through an area vertical to the distribution direction of the radiation. High- frequency radiations are distributed Base Transceiver Station (BTS) and antennae which can be absorbed by biological systems. This paper presents the Comparative Analysis of Power flux density of three major GSM carriers in Nigeria along 91km route of various attenuation rates. Given that the high frequency radiations emitted by BTS and antennae are distributed energy and information over a great distance which can be absorbed by biological systems, it is essential to monitor power radiation levels from time to time ensuring that they are within safety threshold. This measurement was achieved using the developed digital field meter to calculate values of some electromagnetic parameters such as power flux density, electric field intensity and magnetic field intensity. To understand the behavioral pattern of non-ionizing radiation associated with the power flux density due to electric and magnetic field intensity of GSM signal, the developed field instrument (i.e., GSM field meter) was used to calculate power flux density of three GSM carriers along 91km road network. The study provided a standard to monitoring the GSM carriers radiated signals in terms of safety to human being. The study confirmed that the signal strength of MTN mobile network is stronger than the Airtel and Glo mobile networks along the route covered during measurement. The maximum values, even at resonant frequency, are still far less than the International Commission on Non-Ionizing Radiation Protection (ICNIRP) values of 4.5 W/m2 and 9.0 W/m2 for GSM 900 and GSM 1800, respectively.
