The goal of the main project 5G-OPERA is to build a Franco-German ecosystem for private 5G networks under the joint leadership of TU Dresden and EURECOM (Sophia Antipolis). The project focuses on the idea of open hardware, software and interfaces so that multiple providers can participate in the technical equipment of private 5G networks and user needs can be flexibly realized. The overall goal of the project is to ensure that the hardware and software of all project partners can work together technically, independently of the respective manufacturer. In addition to setting up reference test environments and demonstrators in Industry 4.0 environments of both countries, 5G-OPERA is supporting the trials in the three demonstration projects.


  • Establish a Franco-German provider ecosystem for private, virtualized 5G networks based on Open RAN technology
  • Promoting the digital sovereignty of France and Germany as a guiding principle for the European Union
  • Coordinate the mutual Franco-German transfer of campus network concepts, architectures, and solutions
  • Develop open campus network solutions considering operator models in France, Germany, and other European countries

Expected Impact

  • Open RAN market will outgrow traditional RAN market by 2030
  • Open RAN solutions will bring down the cost of deploying and operating private 5G campus networks
  • The developed innovations will be enablers for vertical industries
  • The project will enable partners to provide competitive products on the O-RAN market
  • Testbeds will demonstrate interoperability of the developed components
  • Reinforce digital sovereignty
