Deployment of advanced broadband access networks is a prerequisite for the continuous development and success of broadband. This thesis investigates available deployment strategies for broadband access networks required to support the near-future transmission requirements of converged voice, video, and data services. The approach of telecoms using Digital Subscriber Line technology is compared to entry strategies based on Fibre-to-the-Home to evaluate the financial feasibility of residential broadband deployment in different geographical areas. A fundamental assumption in residential broadband deployment is that the required investments are based on financially feasible premises. Investment appraisal of deployment scenarios is therefore of interest to operators and regulators alike, but is not trivial and relies on knowledge of the technological, economic, and regulatory parameters that affect the foreseen cost and revenue of networks and services. In contrast to existing static methods of evaluating financial feasibility this thesis argues that properties of the networks and services need to be related to competitive interactions between infrastructures when evaluating financial feasibility. To accomplish this, this thesis is divided into three main parts, where the first part analyses properties of packet-based multimedia services and performs quantitative forecasting of near-future transmission requirements.
