The basic task in the designing of future generation wireless mobile communication systems is to forecast the coverage of the area using the available forecasting path loss models before the actual implementation of the design. Forecasting path loss models are mathematical equations which are used to predict the coverage and the performance of the system. The forecasting models are designed for specific terrain conditions and can give varying results when applied to a different terrain type. To analyze the behaviour of the radio frequency channel, experimental data collection was performed in the 1800 MHz band for five GSM cell sites in the densely populated areas of Ghaziabad city with high rise buildings. In this paper the experimental results are compared with the four forecasting models namely, Cost 231 Hata, Cost 231 Walfisch Ikegami (WI), ECC, SUI. Their Average errors and Standard Deviations are compared which reveals that Cost 231 Hata model has the least values and is selected as the best model.
