To engage any nation in wealth creation, human
capacity development and improved standard of living, the need
arises to install trendy technological innovations and efficient
infrastructures such as reliable and efficient telecommunication
systems. This paper therefore, investigates large scale
propagation models used to predict the mean signal strength for
an arbitrary transmitter-receiver separation distance with the
aim of improving the telecommunication system infrastructure
which will engender sustainable infrastructure and technology.
The study has been conducted in an urban settlement in the
Ikorodu – Epe region to develop and optimize a suitable
propagation model based on the existing propagation models.
The proposed propagation models are the Free Space Path Loss
Propagation Model, Okumura – Hata Model, COST 231 Model,
SUI Model and Ericsson Model. The optimized COST 231 model
showed better performance and is proposed for propagation
prediction involving such terrain. Root Mean Square Error
(RMSE) statistical tool was used to achieve the optimizatio
