Covering telecommunications access networks this text puts the emphasis on broadband services, technologies and strategies for developing the existing telecommunications access network towards a full services access network. Techno-economic analyses of case studies on the broad band roll-out expected to take place in the near future are presented. The volume provides a support for establishing guidelines for strategic decisions regarding the development of the access network alternatives of different network operators, including incumbent telecommunication and cable operators and second operators starting from a green field situation. The book is divided into three main sections. The first supplies a general introduction to the evolution of the access network before presenting a comprehensive Delphi survey on emerging services and applications performed by the TITAN project. A description of both the methodology and forecast results are included. The second section concentrates on the methodology and tools developed in the TITAN project in order to assess future introduction scenarios for broadband services and networks.These include the general modelling framework, geometric models for the calculation of the overall cable length of the network, evolution of component costs, sensitivity analysis, risk assessment and the general structure of the TITAN tool. The final section deals with results from applications of the methodology and the tool. Results from ten studies are presented and comparisons made.

The access network is expected to be one of the major battlegrounds of telecommunications network operators, since upgrades of the existing narrowband access network will be the critical factor in supplying multimedia broadband services in a competitive market. The future broadband access network architecture needs to be flexible enough to efficiently support the provision of a full set of broadband and narrowband services with a wide range of capacity demands. A wide range of broadband access technologies are available. Furthermore, the key issues in the upgrading of the very cost sensitive access network are financial as well as technological, both for incumbent and new entrant operators. Thus, in order to identify minimum-risk introductory strategies the economic viability of access network broadband upgrades needs to be carefully assessed. However, despite the definite need for techno-economic evaluations, very few books have been published in this field. One of the reasons might be that broadband access network upgrading only very recently gained wide recognition as a key challenge for broadband delivery. Secondly, this kind of strategic work and these studies tend to be considered rather sensitive by operators, and thus both results and methodologies are not usually readily available. Thirdly, the work reported in this book in many respects was a major pioneering effort, which quite ambitiously aimed at modelling the whole life-cycle costs and revenue streams of access network upgrades, as opposed to several other efforts, which often are limited to pure investment cost comparisons.
