Abstract
This project concerns about the radio propagation models used for the upcoming 4th Generation (4G) of cellular networks known as Long Term Evolution (LTE). The radio wave propagation model or path loss model plays a very significant role in planning of any wireless communication systems. In this paper, a comparison is made between different proposed radio propagation models that would be used for LTE, Okumura-Hata model, Hata COST 231 model, COST Walfisch-Ikegami & IMT-2000 model. The comparison is made using different terrains e.g. urban, suburban and rural area. The model shows the lowest path lost in all the terrains while COST 231 Hata model illustrates highest path loss in urban area and COST Walfisch-Ikegami model has highest path loss for suburban and rural environments.
Fading channel concept considered before study a propagation model which examined the applicability of Okumura-Hata model, Hata COST 231 model, COST Walfisch-Ikegami & IMT-2000 model in GSM frequency band. And accomplish the investigation in variation in path loss between Urban, Suburban, and Ural area. Through MATLAB graph was plotted between path loss verses distance.
