abstract:
globally, research activities have started on 5g communication networks. these research activities are triggered by the ongoing growth of mobile and wireless broadband communications traffic, the huge number of applications and new paradigms like sensor-, iot- or m2m-based systems with a huge number of connected devices. communication networks are also increasingly be used for vertical sectors to manage utility services like energy, gas and water systems and are critical infrastructures for our societies and economies.

the current traffic growth and the huge number of connected devices results in challenging requirements on the energy efficiency of future systems in order to keep the energy- and co2-footprint of future systems as low as possible. the availability of sufficient frequency spectrum is a major concern to support the necessary system capacity. additional challenges are significantly reduced latency for improved user experience, heterogeneous systems, self-organizing networks to cope with the system complexity, a more flexible use of the frequency spectrum and cloud-based architectures. cognitive networks are complementing future systems in order to improve reliability, quality and to reduce operational and energy cost. this is creating huge challenges for research, design and deployment of future communication networks. the network architecture will have to undergo significant changes to meet requirements also to support economic service provision. it will become more flat, virtualization of network resources and cloud concepts reduce capital (capex) investment and operational expenditures (opex) and will allow faster and easier introduction of new services and thereby innovation in service offering. such software-defined networking (sdn) concepts in combination with cognitive systems will support self-organized systems in order to manage the overall network complexity.

future communication networks require a holistic approach in research, standardization, regulations and system development. in europe a 5g infrastructure public-private-partnership is launched as part of the new research framework program horizon 2020, which is providing a framework for cooperating research projects. the cooperation of different research initiatives in the different regions will support future standardization in order to develop globally accepted interoperable systems.

this panel addressed the forthcoming developments and research activities and discussed how global cooperation can be achieved.
