  This paper 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, like Stanford University Interim (SUI) model, Okumura
model, Hata COST 231 model, COST Walfisch-Ikegami & Ericsson 9999 model. The
comparison is made using different terrains e.g. urban, suburban and rural
area.SUI 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.
