Flexible Communication Networks Lab (FlexComNetsLab)
The FlexComNetsLab is manifested in an end-to-end 5G/6G testbed purely based on open-source sofware and own developed software solutions.
Currently the following features are implemented:
- End-to-End Connection over 4G or 5G Stand Alone (SA) with SDR or commercial devices
- Deterministic controller (Chameleon) over backbone for flow guarantees
- Dynamic RAN Slicing (possible to demonstrate multiple UEs over same/different slices)
- Edge computing for prediction of wireless channel state information
- LiFi / WiFi / 5G handover
- Flexible Core Network Function placement
Performance parameters (stable version with OpenAirInterface (OAI):
- FDD: 5/10/20/40 MHz Bandwidth,
- ~ 30 Mbps UL,
- ~ 90 Mbps DL,
- ~ 6 ms RTT UE - Core
Laboratory setup of the experimental end-to-end 5G/6G communication network
The FlexComNetsLab is based on the 5G Research Hub Munich testbed (https://www.5g-munich.de/), which was a joint project with the chair of media technology (LMT) Prof. Steinbach funded by the Bavarian government. It has been further extended and is still being used and enhanced in the 6G Future Lab Bavaria and in the 6G Research Hub 6G-life, funded by the Bavarian government and the German federal government, respectively.
