Abstract

Following the increasing need for higher broadband speeds, the European Commission (EC) has set specific goals to all member states regarding the development of new generation networks. Due to the high deployment cost, many countries have adopted only a partial transition to a purely optical fiber network. Fiber-to-the-Cabinet (FttC) architecture combined with very-high-bit-rate digital subscriber line 2 (VDSL2) and vectoring noise cancellation techniques may provide a more viable short-term solution. Technoeconomic analysis is vital at the initial development stages of a telecom network, which usually require large investments in infrastructure. This analysis addresses the viability of the project from a financial perspective. In this paper, we present a technoeconomic framework for the analysis of VDSL2 vectoring technology with its subsequent G.fast upgrade and illustrate its applicability in a particular suburb of the city of Athens, Greece. A number of different scenarios is evaluated predicting profits even from the first quarters. The analysis includes an estimation of the degree of market penetration, analytical cost calculations for the implementation and operation of the network leading to the evaluation of financial indicators regarding the prospects of the investment in vectoring services. The overall framework can be applied in similar evaluations, regarding the deployment of telecommunication access networks.
