| description | In addition to its rule in achieving acceptable system performance, accurate path-loss estimation leads to realize a simple
and precise estimation of cellular networks financial feasibility. In other words, in cellular networks, while accurate
path-loss estimation helps to achieve a reasonable cost, inaccurate path-loss estimation could either lead to reduce the
cost but degrade the performance, or improve the performance but increase the cost. Thus accurate path loss estimation
becomes a very crucial and desirable goal. To this end, different models were introduced in the literature for achieving
the aforementioned goal; however, each model sought to be a valid choice in a specific environment. Therefore, our main
objective in this paper was to provide an insight to the cellular network designers to simplify the decision-making process. A
number of widely used path-loss estimation models that work in different environments, such as Free-space model, Two-ray
model, Okumura/Hata model, COST 231 model, and Indoor model were reviewed and analyzed. This significantly would
assist any cellular network designer to select an appropriate model according to its working environment, and thus realize
the desirable accurate path-loss estimation. Matlab was used to perform this analysis. The analysis drove us to enter into
implicit comparisons between the aforementioned models. Going through these comparisons, it is concluded that although
an increase in the level of complexity is encountered when using models with large number of correction factors, more
accurate path-loss estimation can be achieved. |
