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...

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...

This article examines three major changes which have been occuring in the telecommunications market: liberalization, leading to increased competition in services and equipment, the internationalization of the equipment market, and a rapidly changing industrial structure. The interrelationship...
