For small and medium-sized companies, affordability is crucial for the adoption and deployment of these solutions. Open-source projects that implement components of the 5 G system are likely to play a key role in reducing the entry barrier for private 5G network solutions. This research paper presents the world’s first voice-over-5G prototype using only open-source projects, successfully implemented at Technische Universität Berlin, along with initial performance measurements.enOver-the-top media servicesPerformance evaluation5G mobile communicationPrototypesPacket lossVoNRconference paper
