Abstract: Very long-term (20+ years) forecasting of broadband traffic in next generation networks requires extrapolations going beyond processing of the past traffic data. Such forecasting is further challenged by the fact that, in 20 years, the current network technologies and architectures will likely be obsolete. The traffic upper-bounds can be obtained by evaluating the limits of human sighting, and then assuming that these limits will be achieved by future services. Alternatively, the contents to be transferred by bandwidth demanding applications can be considered such as those using embedded interactive 3D video streaming. The obtained traffic upper-bounds are a good indication of the peak values, and thus, of the future network capacity demands. In addition, the main drivers of traffic growth will be identified assuming multimedia as well as non-multimedia applications. New disruptive applications and services will be explored that can make good use of large bandwidth provided by next generation networks. These results can be used to identify monetization opportunities of future services, and to map potential revenues for the network operators.

Brief Biography of the Speaker: Pavel Loskot obtained the B.Sc. and M.Sc. degrees in Biomedical Engineering and Radioelectronics from the Czech Technical University, Czech Republic in 1996 and 1998, respectively, and the Ph.D. degree in Wireless Communications from the University of Alberta, Canada in 2008. He has held a number of research positions and visits to Slovenia, Finland, Canada and China, and participated in numerous industrial collaborative research projects since 1996. Currently, he is a Senior Lecturer in Systems and Process Engineering Centre, College of Engineering, Swansea University, United Kingdom. In 2009-2012, he was a co-investigator in the EPSRC/MVCE Green Radio project investigating energy efficiency of the radio access networks. In 2011-2012, he was the principal investigator in the Welsh Government and the British Telecom funded project within the Digital Wales Research Hub investigating traffic and socio-economic modelling of the next generation broadband networks. His main research expertise is in digital and statistical signal processing, and communication and network theory.
