In this paper we consider and evaluate NGA architectures which meet the foreseeable future bandwidth demand and allow for highest bandwidth and quality for end-users and which no longer rely on copper cable elements. These are FTTH architectures only. From all available FTTH architectures we...

VDSL Vectoring is a transmission technology over copper access line pairs enabling the transmission of higher bandwidth to the end customers, but harms the infrastructure based competition using physical unbundled copper lines. Thus regulators have to decide between infrastructure based...

VDSL and G.fast Vectoring are transmission technologies over copper access line pairs enabling the transmission of higher bandwidth to the end customers, but harm the infrastructure based competition using physical unbundled copper lines. Thus regulators have to decide between infrastructure...

It is common knowledge that Next Generation Access (NGA) networks require significant investments and that for many regions, especially in more rural areas, there is no viable business case. In this paper a bottom-up cost modelling approach is applied to determine the investment and cost of...

Our market modelling approach aims at practically determining wholesale pricing policies for the switch from copper to fibre access networks. It asks which market equilibria for incumbents and entrants result from different combinations of copper and fibre wholesale access charges. We first...

There is an ongoing discussion in the market which Next Generation Access (NGA) architecture best suits future needs and which investment and cost differences exist. The discussion can be subsumed as P2P vs. GPON, which is somewhat misleading as this article reveals. The discussion is driven by...

Using a novel approach to the evaluation of new network technologies that combines an engineering cost model with a differentiated multi-player oligopoly model with wholesale access regulation this article evaluates the choice among different Fibre-to-the-Home (FTTH) architectures. The cost...
