Five different proof-of-concept (PoC) demonstrations were presented live to the participants:

  • StaBAK – cityscape-compatible Berlin assembly variant small cell.
  • Network Management and Network Slicing – network management based on ONAP, trouble ticketing & site documentation
  • Digital twins with Instant Neural Radiance Field (NeRF) – Neural rendering of 3D scenes based on image and video material
  • LiFi for indoor applications – Optical wireless data transmission in an office environment
  • Outdoor and indoor 5G RAN – 5G data connectivity with macro cell and O-RAN small cell

A high-profile panel discussion on campus networks, Open RAN and their use in urban environments with Professor Stanczak (Fraunhofer HHI), Dr. Alexander Keller (NVIDIA), Alfons Mittermaier (highstreet technologies GmbH) and Dr. Frank Schramm (Senate Department for Economics, Energy and Operations) concluded the event.
