RESUMO
This work presents a detailed study of planning tecniques for third generation WCDMA cellular systems. At first a theoretical study of the WCDMA system is presented, including the structure of the air interface and the various channel types in the downlink and uplink. Following, network planning techniques are presented, with a detailed analysis of the link budget calculations and the system coverage planning issues. Based on this study, the system behaviour was simulated using the open software NPSW for different configurations of service, operation condition and system load. The simulations allowed the characterization of the effect of several parameters on the system performance. Finally, a case study of coverage planning for downtown Rio de Janeiro is presented.
