ABSTRACT

Planning and dimensioning process of a multi-service network WCDMA should consider the whole parameters characterising the radio cell. Among these, we are interested in the required total BTS power and maximum capacity supported by the cell in the downlink direction. This direction requires more radio resources, thus it is more delicate to optimize. In this context, we express these two parameters as a function of the quality of service (QoS) received at the level of a mobile station activating a certain service (voice, video, etc) and as a function of various radio interface problems such as: multipath, neighbouring cells effect, pathloss, thermal noise due to equipment, etc.
