This paper presents a simulation-aided approach for the dimensioning of the ATM-based iub interface in UMTS/HSDPA networks. Besides considering different user applications, as well as the peculiarities of the radio protocols above and within the backhaul transport infrastructure to estimate Iub utilization, this paper also provides insights in to the HSDPA air interface capacity given different data traffic and voice traffic scenarios for different UE categories (e.g. UE Cat 12, 6, 8). Since R99 PS (Packet Switched) services are less spectral efficient and there is a clear trend to replace such services with HS (High Speed) services in most WCDMA networks, this study focus on the analysis of HSDPA PS data services and only considers R99 radio bearers for AMR voice calls.
