The goal of this contribution is to discuss the benefits of beam steering antennas on downlink dedicated channels (DCHs) of the WCDMA-FDD system, regarding coverage and capacity aspects. Our studies are based on a software tool (WIDEsim- WCDMA downlink dynamic system level simulator), which performs slot-based dynamic simulations of the WCDMA radio access network on the forward link direction. The multicell environment and user mobility are taken into account, aiming at a combined evaluation of radio resource management (RRM) and smart antenna strategies. The RRM algorithms implemented in the simulator are: power-based call admission control, power allocation, power control (open loop and inner loop) and soft(er) handover.
