The practical were obtained during one test-drive made at Porto downtown (CBD), named Baixa. Practical results are compared with application of theoretical models. The urban parametrs was assumed to be position-independent. These results will be of importance for mobile cellular communication systems in macro and microcells scenarios at urban dense areas. Two models to downtown are presented: Regression Line Fit (RLF) and Okumura Baseline Fit (OBF). Generated results confirm the good agreement to the zone under study, due lowest absolute mean errors and standard deviations generated.engconference paper10.1109/CRMICO.2002.1137216
