Propagation Modelling of Path Loss Models for Wireless Communication in Urban and Rural Environments at 1800 GSM Frequency Band

摘要

In this research various channel propagation models of wireless communication systems were analysed. There are many types of propagation models that can minutely calculate the path loss in all types of terrain. Performance estimation of different propagation models was analysed using simulations. In the simulations the selected propagation models have been proposed at the operating frequency of 1800 MHz for different receiver antenna heights in urban and rural environments. Simulations were performed using MATLAB R2013b. The propagation models depend on location, frequency range and clutter type such as urban, suburban and countryside. It was noticed from the results of the path loss calculation for 2 m, 7 m and 14 m receiver antenna heights in urban environment that COST 231 (W-I) model showed the lowest path loss results (138 dB) as compared with the other models in urban environment. On the contrary, SUI model showed the highest path loss result (166 dB in 2 m receiver antenna height) as compared with the other models in the same environment.
