Prediction of path loss in a wireless system is important to determine its quality of service. Fluctuations and variations of signal strength at higher frequency range in Near Field zone, is a common difficulty to achieve higher data rate. Continuous variation in signal causes decay of strength by the interference of the atmospheric obstructions and hence electric field intensity gradually decreases with the distance. In this paper the behaviour of field strength is explored through AWAS Electromagnetic Code which predicts the rapid variations in electric field intensity irrespective of environment as compare to statistical models which do not capture the variations as per Environment. An adequate and optimum values of these parameters is essential for efficient transmission. The results show that the numerical analysis predicts much lower field strengths which could significantly affect the channel quality. . This investigation is essential to reduce the rapid fluctuations in field strength of the WiMAX.
