The paper presents a simulator built to evaluate the uplink and downlink capacity of a WCDMA network in the presence of hot-spots traffic. As the traffic is no longer distributed uniformly, some typical assumptions and approximations used in conventional network simulators become invalid. A new iterative approach to address the problem is proposed and explained. Uplink capacity simulations are performed and the results of the new uplink approach and the conventional one are also compared. This has shown that when performing uplink simulations of WCDMA networks with hot-spots traffic, extra care has to be taken for obtaining accurate results.
