Portable 5G Node Use Cases

5G+ Nomadic Node

To extend a network capacity to a specific location, one of the most attractive use cases is to make the network portable or mobile, enabling private local communication as well as efficient backhauling to a central location or to edge nodes.

  • A portable network can be installed and configured at the specific use case location in a matter of minutes and remain in use for a specific duration of time of the use case (such as for fairs or for construction sites).
  • A mobile network has to be installed in a mobile vehicle and can follow the specific mobile communication needs at their location (such as public parades, public health or emergency networks);

The nomadic 5G edge network is designed to test the feasibility of such a solution for 5G networks:

  • Spectrum usage around the nomadic edge node (licensed and unlicensed)
  • Connectivity of the devices to the local network – connecting the devices to the locally deployed network, including automatic configuration
  • Power management – especially the mobile edge network has to function with the spare power from the vehicle
  • Local offloading of the communication – providing support for private local communication
  • Backhaul selection between satellite and available terrestrial operators – enabling efficient communication with the central locations and the Internet for data, for control plane as well as for the management of the edge network
  • Communication over unreliable wireless backhaul – especially for the mobile network, the backhaul connectivity quality is varying while mobile.

The Nomadic 5G Edge Network was specifically designed to be able to showcase the different use cases at the use case location when needed and according to the use case requirements.

Success Stories

ALADIN: Forest Firefighting in Brandenburg with 5G

The ALADIN project aims to ensure safer forest firefighting in the future utilizing demand-oriented 5G networking of emergency forces and response resources. As a first step, a nomadic, i.e. local and temporary, network is being set up at the Schönhagen airfield in Brandenburg. The network will then be used to enable emergency forces to communicate with each other, unmanned firefighting vehicles to be remotely controlled, and current situation images of the scene to be transmitted by a reconnaissance drone. In this way, it will also be possible to monitor and secure areas where it was previously impossible to enter or drive through due to contaminated sites (in particular unexploded bombs and shells as well as ammunition parts).

Temporary network at the Festival of Lights 2019

Fraunhofer FOKUS conducted a field trial as part of the EU project 5Genesis with partners from the Leibniz Institute Innovations for High Performance Microeletronics (IHP), Humboldt-Universität zu Berlin, Karlstads Universitet, NetApp and Simula Festival of Lights in Berlin on October 2019. The field test took place in front of the main building of Humboldt-Universität zu Berlin, one of the festival's main squares. A 180 degree camera recorded the surrounding light installations on both evenings. Instead of sending the data to a central cloud, the videos were transmitted via a 60 Ghz antenna to an “Edge Cloud”, which was located in a van on site.
