Measurement and Modeling of Path Loss for GSM Signal in a Sub Urban Environment over Irregular Terrain-Review

This work presents measurement and modeling of path loss propagation for three GSM operators in Mubi town. We adopted COST 231-Hata model as a reference model and modified the model based on the experimental data measured in the study area. Autoregressive neural network (ARNN) predicted that the average path loss for each GSM operator is 16.96dB, 16.077dB and 24.5dB with their corresponding mean square error (MSE) as 1.76329dB, 1.2958dB and 2.37112 for AIRTEL, MTN and GLO respectively. GLO operator experienced more path loss followed by the AIRTEL and MTN is the least.
