Test and analysis of local 5G networks and local spectrum as part of digitization of systems for industrial production

Important results from the project

** Denna text är maskinöversatt ** The project has aimed to deepen the understanding of and examine the conditions and obstacles for the industry to build and operate local non-public 5G networks with local spectrum permits in the 3.5 GHz frequency band. verify orders of magnitude on performance and problem. The results have been summarized in 2 reports: - "Guidelines for the planning, construction and operation of local 5G networks for industrial use" - "Background for guidelines for managing frequencies, coexistence and interference"

Expected long term effects

** Denna text är maskinöversatt ** It is easy to implement a local private 5G network. There are several actors who sell solutions. The range of 5G connected tools is very limited, why it is still unusual with 5G. The challenges do not lie in the technology but in using the opportunities offered and integrating these into production and the organization. An important results is the extended coverage that can be achieved with the higher power that the local 5G permits allow. Problems lie in integrating the 5G connected devices with production systems (OT) and administrative systems (IT).

Approach and implementation

** Denna text är maskinöversatt ** A private 5G network for operation in local spectrum has been purchased by Ericsson, installed in Scania´s test factory and operated by Tele2. Åkerströms has developed a system for controlling equipment and industrial processes over 5G. The results show that there are several different actors that sell solutions for 5G networks. However, the range of 5G connected equipment, is limited. The network has not achieved the response times promised and the variations have been too large to be used in process control. However, the system we used is a demo system.
