Abstract
The current trend within the development of the telecommunication networks indicates that the user will constantly be connected to the network independent on the locations and the covering network. In the following, this is defined as “Always on – everywhere”. Being always on everywhere requires more heterogeneous access networks, more intelligent services and a significant increase in the available capacity in the transmission- and the core network as well as a technology convergence.
In the following, we will cover some of the ongoing trends towards a common high capacity infrastructure and what it requires to get there.
An overall view will be presented on how the services, their availability, the bit rates and the infrastructure may develop. Most of the examples are seen from a cellular operator's perspective due to the background of the authors. The content of the paper reflects only the view of the authors and not necessarily the one of the TeliaSonera group.

He has written and co-authored some 9 conference and journal papers on propagation.
Furthermore, Christian Kloch is appointed as External Examiner for Master's level students as well as Ph.D. students within the area of wireless network design.
Peter Karlsson received both his M.Sc. and Ph.D. from the Lund Institute of Technology in 1988 and 1995 respectively. In 1995 he joined the Radio System Group at Telia Research AB (Malmö, Sweden), working on design, analysis and trials with high capacity mobile and fixed broadband radio communications systems. He has been contributing to the standardisation of WLANs in ETSI BRAN and IEEE 802.11 and chaired the HiperLAN2 Global Forum (H2GF) regulatory group 1999 to 2001 aiming at global allocation for WLAN spectrum in the 5 GHz band. During year 2000 he was a research fellow at University of Bristol in combination with a half time position at Telia Research working with adaptive antennas both for cellular and WLAN systems. He has written and co-authored some 50 conference and journal papers on antennas and propagation, mobile and wireless systems and economical studies of related infrastructure. Peter Karlsson was area manager of the Mobile System Innovation projects at Telia Research AB in 2001. He was then appointed expert in radio communications and holding the expert position at TeliaSonera Sweden, Mobile Network R&D until 2004. Peter is now director of EU programs at TeliaSonera Corporate R&D functions.
