ABSTRACT
Path loss is the gradual reduction in the quality of signal service of the Global System for Mobile Telecommunication (GSM) during transmission between a Mobile Station (MS) and a Base Transceiver Station (BTS). Many researchers have studied different Path Loss models; however, the applicability of these models cannot be generalized to all Urban or Suburban areas. The Path Loss prediction model for the Suburban area of the MTN service network at Adamawa State University, Mubi, Nigeria, was undertaken using five different propagation models at different intervals of distance. To determine the best suitable model for the area, RMSE between the Path Loss measured and that of the models’ output was determined as 1.98, 1.40, 0.78,0.88, and 1.84dB for Hata, Cost 231, ECC-33, Ericson, and SUI models, respectively. A comparative study shows that the ECC-33 model was found to be the best model and was adopted, modified, and optimized for quality signal propagation. The path loss of the area was also reduced by 1.9dB which represents a meaningful enhancement in reduced call drop, improved voiced call quality and enhanced data throughput. The optimized model can be deployed by network engineers. It can also be used in designing the network architecture of the study area for good signal propagation.
