This document analyzes the near field distribution variation of WiMAX signals using the AWAS electromagnetic code. It finds that the electric field intensity in the near field zone (within a few hundred meters of the transmitter) fluctuates rapidly due to atmospheric interference and obstructions. The AWAS code is able to predict these fundamental variations based on environmental parameters, unlike statistical models. Experimental data from WiMAX base stations in India's urban areas was used to analyze the effects of transmitter height on electric field distribution - higher heights resulted in larger near field distances but greater fluctuations, while lower heights reduced variations. The analysis provides guidelines for cell planning to optimize signal coverage and efficiency.
