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...

In many countries worldwide access networks are in the transition from copper to fiber access. During the transition phase copper and fiber networks are operated in parallel. All regulators facing this situation of technological change have to decide how to price unbundled access to the copper...

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...

"Im folgenden wird der Versuch gemacht - auf der Basis der Angaben von 1969 Betrieben des verarbeitenden Gewerbes aus dem Jahre 1976 - Arbeitsplätze nach Qualifikationsanforderungen und nach Attraktivität der Arbeitsbedingungen zu strukturieren und zu ermitteln, wo ausländische Arbeitnehmer...

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...

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...
