Περίληψη:
The paper presents the main results obtained within the Research in Advanced Communications in Europe (RACE) project: 2087 TITAN (Tool for Introduction Scenarios and Techno-Economic Evaluation of The Access Network) regarding minimum-risk introductory routes for new narrowband and broadband services in the residential and small business market. The project developed a methodology and a tool for technoeconomic evaluation of advanced narrowband and broadband telecommunications networks and services. Results from four extensive access network studies are presented. For the narrowband services, optical access and radio in the local loop have been assessed and compared to conventional copper layout in a greenfield environment. Access network upgrade strategies for emerging new broadband services have been evaluated in three studies, with technological options ranging from enhanced copper to hybrid-fiber-coax (HFC) and broadband passive optical networks. An extensive study on different broadband access network upgrade alternatives for public network operators (PNO's) were carried out, taking into account the diversity of conditions met today by European countries. In another study, the effect of competition in the access network was modeled assuming two main operators sharing the market. Broadband upgrade alternatives were evaluated for a new cable operator, competing with the dominant public network operator. In addition, video-on-demand (VoD) and Internet access upgrades have been analyzed. The paper demonstrates the viability of techno-economic studies for the access network, including in-depth analysis of the time-dependence of component cost, tariffs, service-penetrations and market shares. This work intends to support establishing guidelines for strategic decisions regarding the development of the access network alternatives of different operators.
