Mobile and wireless communications are the major means for communication between people and increasingly also between devices, sensors and are the key enabler for the Internet of Things (IoT). Currently, mobile broadband communication systems (LTE) are being deployed globally, which will become the major communication means for many Internet and video applications. Data traffic is expected to grow exponentially in the coming years, which will require significantly higher system capacity per area unit in the order of a factor of 1000 between 2010 and 2020. In addition, the number of subscribers for mobile and wireless communication as well as the Internet is continuing to grow globally.

Communication networks today have a share in global energy consumption in the order to 2 %. Therefore, the expected traffic growth is a huge challenge on future communication systems, which have to be much more energy efficient compared to today to avoid a major increase in energy consumption.

These trends are creating huge challenges for research, design and deployment of future communication networks. Additional challenges are significantly reduced latency for improved user experience, self-organizing networks to cope with the increased system complexity, cloud-based architectures and increased flexibility in the allocation of data rates to users by keeping the protocol overhead low. With respect to the growing capacity requirements the identification of additional frequency spectrum including the millimeter wave frequency range for mobile and wireless communications has to be supported as well as research on a more flexible spectrum usage, increased system performance by improved interference management, advanced antenna concepts, cooperative base stations as well as further developments in particular on the system level has to be performed. Heterogeneous networks with cooperating radio systems and a unified radio resource management by using different available frequency bands and the deployment of the most appropriate radio systems in given environments will play a major role. Cognitive networks are complementing future systems in order to improve reliability, quality and to reduce operational and energy cost.

In different regions research activities started on future systems to investigate future developments towards 2020 in order to understand, which technologies and system concepts will solve the challenges. However, there is still a different understanding on the capabilities, usage scenarios and major building blocks of 5G systems. This panel will discuss potential concepts for 5G and major technologies, which will be used and where major research activities will be needed.
