Immediate Coverage Information for Private 5G Pop-Up Networks for Large-Scale Indoor and Outdoor Events


5G pop-up networks, e.g. for major incidents, require information on radio spectrum occupancy during setup and operation. The collection of measurement data by end devices participating in the network eliminates the need for additional measuring devices. The information obtained can be used to locate and organize the operation. The measurement data must be organized with high performance and assigned directly to their measurement position. For indoor areas, the signal information of the 5G pop-up network itself is used by a 5G positioning process.

Goals and Objectives

The focus of the developments in the UVINET project is on the acquisition of terminal-specific 5G measurement data with local reference in 5G pop-up networks. With the information from the E2E app and the associated backend, operators of private 5G campus networks and pop-up networks can monitor the quality of network coverage directly during operation and also locate 5G end devices inside buildings. “Automatic frequency selection” supports the immediate deployment of the 5G pop-up network, as interference can be detected and avoided. This enables efficient radio spectrum allocation, which must be carried out in coordination with the regulator (BNetzA) or the mobile network operators. Based on the ORAN architecture, the technical basis is provided for the direct use of indoor positioning, which is also of great benefit in conventional 5G networks. The demonstrator shows the technical feasibility of dynamic provision of 5G networks and effective frequency utilization.
