Abstract
Wireless communication networks heavily rely on accurate radiowave
propagation models for optimal system design and performance evaluation. In
this research paper, a comparative study of COST 231-Hata, Log-normal and 2-ray
radiowave propagation models suitable for wireless communication networks were
carried out. The objective is to assess the strengths, limitations, and
applicability of these models across different scenarios, aiding network
planners and researchers in selecting the most suitable model for their
specific requirements. The theory of each of the three models were studied and
simulated. Simulation results were analyzed in excel and results showed that
2-ray model is quite different from COST 231-Hata and Log-normal. An
experimental measurement of the received signal power for MTN 4G network
serving polo park area was also carried out. The experimental result reveals a
percentage decrease in received power of 18.09, 35.23, 362.00 and 4.66dBm for
Cost 231-Hata, Log-normal, 2-ray and experimental measurement respectively for
a distance of 200m from the base station. This result confirmed 2-ray model as
an outlier and not suitable for wireless network propagation prediction. The
result also show that Cost 231-Hata is the most suitable radiowave propagation
model for wireless when compared with Log-normal and 2-ray. For more accurate
and robust prediction algorithm, it is recommended that more empirical models
be involved and used to develop a system that selects the best model for radiowave
propagation prediction.
