By using propagation path models to estimate the received signal level as a function of distance, it becomes possible to predict the SNR for a mobile communication system. Both theoretical andmeasurement-based propagation models indicate that average received signal power decreases logarithmically with distance. For comparative analysis we use Okumura’s model, Hata model, COST231 Extension to Hata model,ECEC-33 model,SUI model along with the practical data. Most of these models are based on a systematic interpretation of theoretical data service area like urban(Built-up city or largetown crowded with large buildings), suburban (having some obstacles near the mobile radio car, but still not very congested) and rural (No obstacles like tall trees or buildings like farm-land, rice field, open fields) in INDIA at 900MHz & 1800MHz frequency . |
