Tiivistelmä

The target of this paper is to evaluate the impact of geographical traffic load distribution of a cell on the optimum downtilt angle of macrocellular WCDMA network. Moreover, the target is to solve possible capacity gain from CAEDT concepts, and to provide ideas for parameter selection for CAEDT algorithm. Initial results reveal how optimum downtilt angle changes from 6° to 10° depending on whether traffic is concentrated closer to cell edge or closer to base station. Under different traffic load distributions, the network capacity changes with aforementioned tilt angles, which indicates of a possible capacity gain from a fast rate CAEDT.
