Planning the evolution to broadband access networks: A multicriteria approach

Abstract

The interplay between continuing technical innovations, development of multifaceted modes of communication and market structure, among other factors, have raised new and complex problems concerning the strategic modernisation planning of telecommunications networks, namely regarding the evolution paths towards a wide range of new service oerings to be delivered to homes by using broadband technologies. However, decisions must be made by telecommunications operating companies or administrations in a turbulent environment, full of uncertainties with respect to reliable demand forecasts (for new services for which no past data is available), production costs and time to reach the market of some equipment based on brand new technologies, development of new services, etc. Moreover, strategic decisions to be made generally involve distinct, incommensurate and con¯icting aspects; that is, problems are multicriteria in nature in the sense that economical, technological, market and social aspects are at stake. Therefore, in order to make well founded decisions, models should explicitly address those dierent objectives, so that decision makers and planning bodies may grasp the con¯icting nature of the objectives and the trade-os to be made in order to select satisfactory evolution plans. This paper presents a multicriteria model, which extends previous work by the authors, aimed at studying the evolution scenarios to deploy new supporting technologies in the access network to deliver broadband services to individuals and small enterprises.

A Cost Effective Topology Migration Path Towards Fibre

“…Ref. [8] presents a multi-criteria model aimed at studying the evolution scenarios to deploy new supporting technologies in the access network to deliver broadband services to individuals and small enterprises. This model is based on a state transition diagram, whose nodes characterise a subscriber line in terms of service offerings and supporting technologies.…”

Contribución al estudio de la viabilidad de operadores de telecomunicaciones de acceso inalámbrico fijo mediante el desarrollo de escenarios tecno-económicos

“…Por eso sus condicionantes, aproximaciones y potenciales ha sido ampliamente estudiados (por ejemplo, Wack, 1985aWack, , 1985bSchoemaker, 1995;Schwartz, 1996;Godet, 2000). Junto a ello, muchos son los modelos tecnoeconómicos que se han propuesto para aplicación en los más diversos escenarios, desde las redes cableadas de banda ancha (Olsen et al1996;Ims et al 1996;Antunes et al 1998) a las de móviles, posiblemente uno de los entornos más variados dado el auge de las tecnologías que lleva asociadas (Katsianis, 2001;Bjorkdahl and Bohlin, 2002;Varoutas et al 2003;Park and Chang, 2004).…”
