Performance of Path Loss Model in 4G Wimax Wireless Communication System in 2390 MHz

In 4G WiMAX wireless communication system, the signals like all RF wave, are susceptible to path loss. Path loss represents the attenuation suffered by an RF signal as it propagates from the transmitter to the receiver through various terrains and is considered an important element in designing a radio link. This paper outlines how an optimised model for the prediction of path loss for WiIMAX signals up to 2390MHz band is developed based on measured field strengths in Cyberjaya, Malaysia. The data is collected at 50m radial increments within 1km from the base station using a directional CPE.
