Abstract [en]

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.
