A variety of access networks will coexist in the future, with the aim to meet the optimum cost and performance for its purpose and target market in its own business case. There are already a number of standards available or currently under development for providing data services in wireless access networks, these standards can be roughly grouped into two camps, the 3G standards and the IEEE standards.
In this thesis, a techno-economic analysis was carried out to explore to what extent the IEEE standards (802.11x, 802.16x) constitute a substitute to 3G. Case studies are adopted as the primary methodology of investigating the possibility of providing broadband wireless service with high area coverage to the residential markets. Different deployment strategies are suggested for a mobile network operator (MNO) and a broadband provider (BP), respectively.
The results indicate that the IEEE standards are not likely to constitute a substitute to 3G under the case study assumptions and from both an operator perspective and a service perspective. HSDPA will be the primary choice of technology for the MNO, while two alternative choices exist for the BP, namely a ‘Greenfield Operator’ case and an integrated WiMAX and WLAN case. Only peak data rates that correspond to normal ‘3G’ service are cost efficient to be offered by the operators if high indoor coverage requirement is targeted. Broadband wireless services can only be profitable with limited indoor coverage. Besides, the results suggest a more profitable outcome for the MNO in providing the same type of services under the same assumptions. Furthermore, the sensitivity analysis on two different traffic demand growth scenarios suggest that the MNO has more to gain by offering broadband data services to special market segments at a higher price, in particular, with a shorter investment horizon. Thus, further study should still focus on solving the optimization problem of adapting the technical performance to the suitable market segments in the practical network deployments.
