Comparative Study and Techno-Economic Analysis of Broadband Backbone Upgrading: a Case Study

In this paper we compare and evaluate suitable methods for delivering broadband services at the metro and backbone level. In particular, the paper presents a techno-economic analysis of two key broadband technologies for metropolitan and backbone networks: The studies are based on a modelling methodology for network value analysis that involves CAPEX and OPEX calculations, while the overall technology deployment financial assessment is based on techno-economic evaluation measures such as net present value (NPV) and internal rate of return (IRR). The studied case is the Telekom Slovenia network which is the incumbent operator in Slovenia. The study is based on the operator data and plans. It deals with the upgrading the current network backbone and takes in account future development and trends of broadband services in the country.
