Abstract [en]

Multi-access networks and hierarchical cell structures are two common capacity expansion strategies for mobilenetwork operators. In both cases costs can be minimized fora set of available radio access technologies, given heterogeneous requirements on area coverage, capacity and quality of service. In this paper we quantify the infrastructure cost for a multi-accessnetwork composed of macro cellular HSDPA base stations and IEEE 802.11g WLAN access points. The network is dimensioned for an urban environment using a stochastic model for heterogeneous traffic density.With the used assumptions and modelling it is shown that a combination of HSDPA base stations deployed with 400mcell radius together with WLAN in hot spots are suffcient foraver age traffic densities up to around 50Mbps/km2 (50 timesthe traffic of typical private voice users today). In order to evaluate the sensitivity to different design features, we introducethe elasticity of infrastructure cost and can thereby show that it is more important to improve capacity in HSDPA than coverageper 802.11g access point. However, with a sparse deployment of HSDPA macro cells (800m radius) infrastructure cost ismore elastic to 802.11g coverage. The paper also indicatessome possibilities to differentiate future radio access technologies towards current systems.
