The 5G Vision

The 5th Generation (5G) of mobile networks aims to define a new radio access and core network as well as new kind of devices and applications. It represents the complete (virtualized) ecosystem: convergence of wireless, fixed and satellite access networks (including the convergence of 4G legacy wireless networks), core networks, backhaul, management, and the efficient end-to-end application delivery.

Current understanding converges to a 5G system view covering a wide set of application requirements and scenarios crystallizing in generic buzzwords like Ultra High Capacity, Very Dense Crowds of Users, Ultra Mobility, Energy and Cost Efficiency and Very Low Latency and system key performance indicators of 10 Gbps peak rates, 1000x capacity per area at hotspot locations, support of a 100 times higher number of devices per cell, a 10x longer lifetime for battery powered devices and latencies below 1ms for Tactile Internet applications.


5G Berlin puts an explicit focus on key issues like e.g. massive wireless device connectivity, utilization of high frequency spectrum for backhaul and access, better exploitation of the spatial channel dimensions using massive MIMO antenna technologies which are of extreme relevance for machine type communication and high capacity densified networks. Furthermore, 5G Berlin provides a unique combination of an outdoor wireless test facilities and a photonics technology research lab enabling researchers to conduct full end-to-end networks tests including a whole set of new core network functionalities required for multi-connectivity of devices and network elements. An important aspect is in this context also the flexible design of 5G core networks in accord to specific application needs with full support of standard compliant Software-defined Networking (SDN) and Network Function Virtualization (NFV) allowing the instant and scalable deployment of different network and service control platforms, with particular emphasis on Machine-2-Machine and Internet of Things enablement.

Ultra-High Capacity

The predicted increase of internet traffic volume exceeds a factor of 1.000 in average. 5G access and core networks have to provide solutions allowing 1.000 to 10.000 fold capacity proliferation at locations of high demand.

Mobility

Ubiquitous wireless connectivity requires ubiquitous mobility support everywhere – starting from portability of wirelessly interconnected devices to support of high speed backhaul from trains, busses and air-planes.

Low Latency

Cyber-Physical Systems like robots, remote operation of machines w and w/o humans in the loop require significant faster control loops over the air in order to enable the Tactile Internet of the future.

Energy Efficiency

Billions of devices and nodes connected in the Internet of Things require low power transmission and communication protocols for longer standby times of devices.  In order to cope with a 1.000-fold increase in wireless capacity a significant reduction of energy per transmitted / transported bit from source to destination will be crucial for a sustainable backbone of the information society.

Reliability

Many new applications will depend on the reliable information exchange far beyond the SOTA best effort connectivity in wireless networks. The reliability feature will enable e.g. introduction of wireless bus systems in automation, machine control and many other application areas nowadays limited to cable based systems.
