This paper presents path loss analysis and computer simulation in
selected environments in Akwa Ibom State. The research work was
carried out in four environments namely; dense-urban, urban, sub-
urban, and non-urban environments. Measurements of path loss
were carried out through drive test using TEMS Software. COST231
Hata model was chosen as a reference model because of its
peculiarity which makes it useful for predicting signal strength in all
environments. It operates with a frequency range that extended to
2100 MHz with a signal strength prediction of up to 10km from the
transmitter to the receiver. The system acquired antenna height
requirement of 30m to 200m for the transmitter and antenna height
of 1m to 10m for the receiver. COST231 Hata model was modified
to form a new optimized model. The result obtained shows that the
optimized model was found to predict a better path loss with RMSE
values of 2.70dB, 1.60dB, 3.12dB, 5.62dB for 2G-900MHz, 2.66dB,
2.70dB, 4.83dB, 5.08dB for 2G-1800MHz and 4.04dB, 2.43dB,
4.48dB, 6.25dB for 3G-2100MHz respectively. In conclusion, it was
observed that the RMSE values obtained from the optimized model
was lower than those obtained from the predicting model and at the
same time, it meets the 6dB standard of the prediction model.
