The significant increase of internet traffic is to a large extent caused by more high-data-rate applications like file-sharing etc. Although network operators constantly increase router and line capacities, overload occurs from time to time, causing delays, jitter and packet-losses at the data...

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...

This paper means to add to empirical research on the impact of local loop unbundling (LLU) on broadband networks. In particular, it focuses on broadband investment made by entrants. Starting from late Nineties telecommunications incumbents of several European Union countries have been required...

The introduction of mobile broadband technology, smartphones and dongles has resulted in a tremendous increase of mobile data traffic. Future demand for more capacity can be met by allocation of more bandwidth and new spectrum bands to mobile communication. But spectrum is a scarce resource and...
