摘要：In wireless communication systems, path loss models are used to find out the path loss between transmitter and receiver. In this paper, Okumura, Cost-231, Hata, ECC 33 and SUI propagation models are discussed. Path losses are estimated using these models in urban, suburban and rural areas. The signal strength are then estimated in all the three environments and also compared with practical data. Comparison is done to find the best model which shows the closest value to the measured practical data.
