Abstract
This research studies the propagation prediction variations of
three models over a Nigerian urban environment and the development
of a suitable propagation prediction model for the environment. The
measurements of the received signal strength at various distances for
nine base stations were conducted at Celtel,Kano. The measurement
equipment used consists of a Test Mobile System (TEMS) connected to
GPS and radio antennas. The TEMS was mounted inside a car that
was driven along an open route for each of the sectors selected from
the nine base stations. Three macro cell propagation models: COST-
231 Hata, Lee and COST-231 Walfisch-Ikegami models were examined
with respect to nine base stations of Celtel, Kano. The results gave
mean prediction error values of –0.7dB,-4.2dB and 8.9dB for COST-
231 Hata, Lee and COST-231Walfisch-Ikegami models respectively.
The analysis show that the COST-231 Hata and Lee models
underestimate the path loss for this environment, while the COST-231
Walfisch-Ikegami model over predict the environment. The new
propagation prediction model was developed from the three modified
propagation models.
