Abstract
Accurate knowledge of the system capacity is neces- sary for planning of packet-switched wireless networks. Although packet services like FTP download or web browsing are not as critical with respect to delay as circuit-switched services, the user expects Quality of Service guarantees to be fulfilled. The assumed traffic model and the guaranteed Quality of Service as well as strategies for scheduling the users have impact on the system capacity. Estimates of the system capacity can be obtained by system level simulations. In this paper, it is shown that the system capacity for FTP traffic with a low subscribed data rate and a high number of users is comparable to the case when each user has always data to transmit and no QoS is considered. This is no longer valid if the number of users is decreased due to a higher subscribed data rate, or if the traffic model has a more bursty characteristic such as web browsing. This leads to a decreased average sector throughput which has to be considered in the network planning process.
