This contribution presents some simulation results obtained by a WCDMA base station equipped with an adaptive antenna system. The results show that the performance gain obtained by an advanced antenna system could be substantial compared to an ordinary sector covering system. Migrating some existing sites/sectors to adaptive antenna systems can be seen as one attractive solution that increases capacity in a coverage area without condensing the system by building additional cell sites. To find out where this grow-on-site migration strategy is most beneficiary, it is important to evaluate the systems by taking typical user scenarios into account. The user scenarios includes spatially distribution of users as well as the expected user behavior related to the actual application (or user data rate). It has been shown that the gains using adaptive antennas for the investigated scenarios of non-uniformly distributed mixed service users are substantial
