Optimization of AIRTEL GSM signal quality for Adamawa State University, Mubi

Abstract

Path Loss is a gradual attenuation of the Global System for Mobile Telecommunication (GSM) signal when transmitted between the Base Transceiver Station (BTS) and Mobile Unit (MU). Network engineers use Path Loss in the designing and planning of their network signal. Path Loss models also help network engineers in optimizing their network signal for deployment. This research work considers the applicability of the Hata model in the suburban area of Adamawa State University in the Mubi North Local Government Area. The average root mean square error (RMSE) between the predicted and measured was obtained as 1.65 dB, which falls within the 6 dB for good signal propagation. The model of the area was optimized and can be used by the AIRTEL network for deployment in the study area in order to provide quality of service (QoS). The relationships between Path Loss and Temperature, Humidity, and Wind Speed were obtained as 0.044, 0.058, and 0.257, respectively. The results show a linear relationship between Path Loss and the weather parameters; hence, it does not exert any effect.
